If you want to add a new XML page source, click the Add Source toolbar button. This brings up the first screen of the Add Page Source dialog (screenshot below). You now have two options:
•To create the structure manually yourself, select New, empty XML, HTML or JSON.
•To import the structure from a file, select New XML, HTML or JSON structure imported from file. If the XPath-based file name option is selected, then the Edit XPath/XQuery Expression dialog appears and you can build an XPath expression to generate the file URL you need. Otherwise, a dialog box appears in which you can select the file that provides the structure of the page source. You can browse for the file, or use a file URL or global resource.
Click Next to go to the second screen of the dialog. Here, you (i) specify that the data type of the page source must be XML and (ii) define the other properties of the new page source. If you are not sure about how to define these properties, then use the default settings. You can always change the settings later by right-clicking the root node of the page source.
When you click Finish, a root node named $XML is created for the new page source (see screenshot below). You can change the name of the root node if you like by double-clicking in it to edit. If you specified that the structure of the page source must be imported from a file, then, on clicking Finish, you will be prompted to select an XML file. The page source $XML will, in this case, be created with the structure of the selected file.
You can now (i) create or modify the structure of the page source via the toolbar commands, and (ii) add data to nodes of the page source. How to do this is described in the section, Tree Data.
Note: You can change the data type of the page source (to HTML or JSON) via the root node's context menu command Data Type.
Working with serialized XML
When dealing with data transfers, you might need to work with serialize XML. MobileTogether's Load/Save String action provides serialization functionality geared to use in its page sources. Serialization of JSON data is discussed in JSON Sources.
