Note The XML Document task pane also disappears if you switch to the Mail Merge task pane, because the data view is applied if you start a mail merge.
I tried inserting XML from another file into my document, but it didn't work.
Microsoft Word does not validate the syntax of the XPath expression that you type. If the XPath expression is incorrect, Word cannot insert the XML.
Word doesn't open my XML file properly.
The file must use proper XML syntax (it must be well formed)
If the XML file is not well formed, Word displays a message. In the message dialog box, click Details to read the XML error message. Then, open the file in a text editor to correct the problem, and try to reopen the file in Word.
If you're editing a file in Word and intend to save only the XML data (discard the Word XML schema), avoid saving the document when it is not well formed. For example, in the XML Structure task pane, check to make sure that you have just one root element defined for the document.
Note The XML Structure task pane displays errors where the XML structure does not follow the rules of the attached XML schema (validation errors), but the pane does not report syntax errors where the document is not well formed. To find XML syntax errors, open the file with a program that reads XML and reports errors, such as Microsoft Internet Explorer 5 or later.
There must be XML tags in the document if you are saving data only
Word must be able to apply an XSL Transformation
When I saved my XML file, I lost some data.
If you apply an Extensible Stylesheet Language Transformation (XSLT) when you save your XML file, Word saves the result of the transformation, not the original XML file. If your original XML file contains data that the transformation does not use, then that data is discarded. To solve this problem, keep a separate copy of the XML file with no transformation applied, and when you apply a transformation, use Save As to create a new file.
The list of elements is hard to read.
