Hello,

I would like to manipulate XML files the same way Java source files can be
manipulated via JDT (using the Abstract Syntax Tree - AST). I understood
that there is an XML API in WST that cand be used for this purpose.

Do you know where I could find some documentation on how to use the XML
manipulation API that is included in WST (IStructuredModel, IDOMDocument,
IDOMElement).

Many thanks in advance.
Cristi.

For most functions, you can use the the standard DOM interferaces to
manipulate the code. Take at the org.eclise.wst.xml.core.tests plugin
and source for examples on how to use the IStructuredModel to get a
model of the document, and then retrieve the DOM document or
(IDOMDocument etc).

From there you can use either the standard DOM interfaces or the
extended IDOMDocument, IDOMNode, IDOMElement, etc interfaces to
manipulate the tree.

You can also use XPath to query and retrieve nodelists which may be
quicker in many cases than walking the tree yourself.

Hello Dave,

And thank you for the hint.
I see that all the classes from
org.eclipse.wst.sse.core.internal.provisional package are marked with a
discouraged access. Is there another recommended way of iterating the
nodes (without making use of the classes in the above package)?

You have mentioned XPath. Is there an example on how to use XPath with
wst.xml infrastructure?

Best regards,
Cristian.

I am referring to the
org.eclipse.wst.xml.core.internal.provisional.document package as well.

Provisional means it's being considered for API usage. You can use it
as it's been pretty stable for the last 4 years (that's about how long
it's been in provisional status).

Hopefully we can address some of this in the coming releases to remove
the internal.provisional package markers.

So even though it says discouraged access, you can use it, just realize
at some point the package name will probably change when we take it out
of provisional status.

The other way is to not use the IDOMDocument, IDOMElement, etc, unless
you need to and work off the org.w3c.dom interfaces, which the above extend.
