Use WTP XML model for programatically modifying a file [message #213487]

Hello!

In the IAM project proposal [1], we provide actions that modify an XML
file in behalf of the user. This file can also be edited through the XML
editor or a Forms-based editor.

I was wondering if we could use a single model (I think the easiest will
be the XML editor model) for manipulating the file.

Is that possible? Can we use the WTP model even when the file is not
open? Would additions through this model keep the original formatting of
the document? How tolerant is it to syntax errors?

If it is not possible, any recommendations regarding how to synchronize
changes through the multiple models?

Yes, you can use the WTP's StructuredDocument programmaticly to create
and edit the documents. It supports both it's own API as well as an
enhanced but compatible DOM Level 1 and partial Level 2 API interface.

I would recommend checking out the SourceEditing Unit Tests for seeing
how to create a StructuredDocument without loading a file.

I'm not familiar with WTP project structure (yet). Could you point me to
the specific project so I can checkout and review it.

Another question... is this also available in WTP 2.x or only in the
upcoming 3.x versions?

Thanks!

2.x and 3.x have the ability to get the DOM from the StructuredDocument.
Actually all versions of WTP have this ability.

The source for the unit tests can be found in the Web Tools CVS
repository under

/cvsroot/webtools/sourceediting/tests

For there you can check out the

org.eclipse.wst.xml.ui.tests
org.eclipse.wst.xml.core.tests
org.eclipse.wst.sse.core.tests
org.eclipse.wst.sse.ui.tests

These should give you enough to get you going.
