I am trying to develop a simple multipage editor that has 2 pages. The
first page is an eclipse form with a couple input fields, and the second
page is the source xml file. I am able to create both pages, but I am
missing a fundamental concept - how do I link the form page to the source
xml file? In other words, how can I have the input on the form page
automatically update the related field in the xml file when it is edited?
Does anyone have a simple example of how this works?
I have searched through the newsgroup and read through the help, but this
has not been clear to me. I have tried to trace through the code for the
Plugin Manifest Editor but have been unable to follow it.
My assumption is that I need some sort of listener on the input field,
probably a ModifyListener, which will open the xml file, parse it for the
correct field, update the field, and then refresh the source page. Is
this the correct approach?

hi, tim, you can analyze the source code of WST XML editor , which is a
two-page editor.
1 Record the line nubmer of every xml element when resolving XML file.
2 Every UI widget you constructed need contain a property whose value is
line number for according xml element.
you can do it like this :
widget.setData("StartLineNumber",elementLineMap.get(element));
