The structure of the XML file is shown below. Just for illustration purpose, I name all the text-boxes the same as the XML nodes. It will look weird if you allow user to select the text.

This box will hold the name of the node. Below is the code that loads the XML object. You can add this code to the Frame 1 of the FLA main timeline. We are using the URLLoader class to load the file. Note that the file can be on a different folder or a different server if the file is on a different server, the other server must have a cross-domain policy that permits you to load the file. Read more about cross-domain policy on the Macromedia site. It is worth noting that when you load external file like this, you should not assume that the file is loaded immediately.

Because Flash does not know how large the file is, it runs the process in the background while the movie continues to run. However, Flash is thoughtful enough to notify us when the file has completely loaded by sending an event. Now we can start accessing the data on the XML. You should be seeing the xml content printed on the textbox. We already know from the XML file that the node should have 3 child nodes header, content, and info.

The output is The order is always the same as in the XML file. Continue to Part 2. Javascript is disabled in your web browser. Please enable it see how. You can use regular text file to pass external data — see here. Yet another way to pass external date is to embed the data using the query string or using FlashVars.

Some general Flash Action Scripting knowledge and syntax. Some basic XML knowledge hierarchical structure, formatting. A node can only have one parent, but a parent can have multiple children. Typically the space available for a directory or file is the same as the space available on the volume containing the directory or file.

However, space available can take into account quotas and per-directory limits. Adding a file or directory to a volume generally requires more space than the actual size of the file or the size of the contents of the directory. For example, the operating system may require more space to store index information. Or the disk sectors required may use additional space.

Also, available space changes dynamically. So, you cannot expect to allocate all of the reported space for file storage. The default encoding used by the host operating system. Possible values include "windows" "shift-jis" , "cn-gb" , "iso" , and others. For a complete list, see Supported Character Sets. The URL for this file path.

If this is a reference to a path in the application storage directory, the URL scheme is "app-storage" ; if it is a reference to a path in the application directory, the URL scheme is "app" ; otherwise the scheme is "file". The user's directory.

The userDirectory property provides a way to reference the user directory that works across platforms. If you set the nativePath or url property of a File object directly, it will only work on the platform for which that path is valid. If an operating system does not support a user directory, a suitable directory in the file system is used instead. The constructor function for the File class. If you pass a path argument, the File object points to the specified path, and the nativePath property and and url property are set to reflect that path.

Although you can pass a path argument to specify a file path, consider whether doing so may result in platform-specific code. You can then use the resolvePath method to get a path relative to these directories.

For example, the following code sets up a File object to point to the settings. A URL uses the file:, app:, or app-storage: scheme prefixes.

However, if the valid URL prefixes are omitted, the path string is treated like a native path and no decoding takes place. You must take this behavior into consideration when validating paths derived from potentially untrusted sources. If you simply validate the input string, URL decoding may allow an attacker to bypass your validation checks. Always validate the final path of the instantiated File object:. The following are valid values for the path parameter using URL notation:.

The app and app-storage URL schemes are useful because they can point to a valid file on all file systems. However, in the other two examples, which use the file URL scheme to point to the user's desktop directory, it would be better to pass no path argument to the File constructor and then assign File.

If you specify a native path, on Windows you can use either the backslash character or the forward slash character as the path separator in this argument; on Mac OS and Linux, use the forward slash.

The following are valid values for the path parameter using native path notation:. However, for these two examples, you should pass no path argument to the File constructor and then assign File. Displays a directory chooser dialog box, in which the user can select a directory. When the user selects the directory, the select event is dispatched.

The target property of the select event is the File object pointing to the selected directory. The directory chooser dialog is not always displayed in front of windows that are "owned" by another window windows that have a non-null owner property.

To avoid window ordering issues, hide owned windows before calling this method. Note: On Android devices, browseForDirectory is not supported. The File object dispatches a cancel event immediately. Parameters title : String — The string that is displayed in the title bar of the dialog box. Displays the Open File dialog box, in which the user can select a file to open.

When the user selects the file, the select event is dispatched. The target property of the select event is the File object pointing to the selected file. The Open File dialog is not always displayed in front of windows that are "owned" by another window windows that have a non-null owner property. Note: On Android devices, the file dialog title cannot be set. The title parameter is ignored.

If you omit this parameter, all files are displayed. For more information, see the FileFilter class. Displays the Open File dialog box, in which the user can select one or more files to open. When the user selects the files, the selectMultiple event is dispatched. The target property of the select event is this File object. Unlike browseForOpen , with the browseForOpenMultiple method, this File object is not updated to reference any of the chosen files.

Instead, the resulting selectMultiple event contains an array of the chosen files. Displays the Save File dialog box, in which the user can select a file destination. The target property of the select event is the File object pointing to the selected Save destination. The Save File dialog is not always displayed in front of windows that are "owned" by another window windows that have a non-null owner property. Canonicalizes the File path. If the File object represents an existing file or directory, canonicalization adjusts the path so that it matches the case of the actual file or directory name.

If the File object is a symbolic link, canonicalization adjusts the path so that it matches the file or directory that the link points to, regardless of whether the file or directory that is pointed to exists. On case sensitive file systems such as Linux , when multiple files exist with names differing only in case, the canonicalize method adjusts the path to match the first file found in an order determined by the file system.

Returns a copy of this File object. Event registrations are not copied. Note: This method does not copy the file itself. It simply makes a copy of the instance of the ActionScript File object. To copy a file, use the copyTo method.

Copies the file or directory at the location specified by this File object to the location specified by the newLocation parameter. The copy process creates any required parent directories if possible. When overwriting files using copyTo , the file attributes are also overwritten. Parameters newLocation : FileReference — The target location of the new file. Note that this File object specifies the resulting copied file or directory, not the path to the containing directory.

If true , the operation overwrites existing file or directory of the same name. Begins copying the file or directory at the location specified by this File object to the location specified by the destination parameter. Upon completion, either a complete event successful or an ioError event unsuccessful is dispatched. If true , the operation overwrites any existing file or directory of the same name. Creates the specified directory and any necessary parent directories.

If the directory already exists, no action is taken. Returns a reference to a new temporary directory. This is a new directory in the system's temporary directory path. This method lets you identify a new, unique directory, without having to query the system to see that the directory is new and unique. You may want to delete the temporary directory before closing the application, since on some devices it is not deleted automatically.

Returns a reference to a new temporary file. This is a new file in the system's temporary directory path. This method lets you identify a new, unique file, without having to query the system to see that the file is new and unique. You may want to delete the temporary file before closing the application, since it is not deleted automatically.

Deletes the directory. If this File is actually a symbolic link to a directory, then the link, and not the directory, is removed. When false , if the directory contains files or directories, a call to this method throws an exception. Deletes the directory asynchronously. When false , if the directory contains files or directories, the File object dispatches an ioError event. Deletes the file. If this File is actually a symbolic link, then the link, not the target file, is removed. Deletes the file asynchronously.

Returns an array of File objects corresponding to files and directories in the directory represented by this File object. This method does not explore the contents of subdirectories. Asynchronously retrieves an array of File objects corresponding to the contents of the directory represented by this File object.

Finds the relative path between two File paths. The relative path is the list of components that can be appended to resolved against this reference in order to locate the second parameter reference.

Optionally, relative paths may include ".. Parameters ref : FileReference — A File object against which the path is given. Returns an array of File objects, listing the file system root directories.

For example, on Windows this is a list of volumes such as the C: drive and the D: drive. An empty drive, such as a CD or DVD drive in which no disc is inserted, is not included in this array.

On file systems for which the root is not readable, such as the Android file system, the properties of the returned File object do not always reflect the true value. For example, on Android, the spaceAvailable property reports 0.

Moves the file or directory at the location specified by this File object to the location specified by the destination parameter. To rename a file, set the destination parameter to point to a path that is in the file's directory, but with a different filename. Parameters newLocation : FileReference — The target location for the move. This object specifies the path to the resulting moved file or directory, not the path to the containing directory. Begins moving the file or directory at the location specified by this File object to the location specified by the newLocation parameter.

Moves a file or directory to the trash. Note: On operating systems that do not support the concept of a recoverable trash folder, the files are removed immediately. Asynchronously moves a file or directory to the trash. Opens the file in the application registered by the operating system to open this file type. AIR prevents you from using the File. On Windows, AIR prevents you from opening files that have certain file types files with specific extensions, listed below.

Attempting to open one of these files using the openWithDefaultApplication method results in an exception. However, AIR applications installed with a native installer extended desktop profile applications are not restricted by these limitations; they can open files of any type.

The tables below list file extensions that are prohibited on Windows, as well as the prevented applications on Mac OS and Linux:. Creates a new File object with a path relative to this File object's path, based on the path parameter a string. You can use a relative path or absolute path as the path parameter. If you specify a relative path, the given path is "appended" to the path of the File object. However, use of ".. The resulting reference need not refer to an actual file system location.

If you specify an absolute file reference, the method returns the File object pointing to that path. Using the backslash character can lead to applications that do not work on other platforms. Parameters path : String — The path to append to this File object's path if the path parameter is a relative path ; or the path to return if the path parameter is an absolute path.

Dispatched when a directory list is available as a result of a call to the getDirectoryListingAsync method. Dispatched when the application requests permission to access filesystem. Check the value of status property to determine whether the permission was granted or denied. Dispatched when the user selects a file or directory from a file- or directory-browsing dialog box. Dispatched when the user selects files from the dialog box opened by a call to the browseForOpenMultiple method.
