Yes.
1) Attribute management is a pain, since XPath identifies only the
attribute node i.e. the name AND the value. Hence a <replace> on an
attribute with a text() node is not going to work.
2) The error message should be much better!
3) I think that the <attr> command needs to handle buffers. I will try and
do 2) and 3) for a new release soon.
4) You can get around this by using properties. This is a bit of a pain,
since properties are expanded for EACH <xmltask> invocation (actually Ant
task invocation). So you have to set the property in one <xmltask> and use
it in another :-(
Thus:
<xmltask source="c.xml">
<copy path="/a/b/text()" property="p"/>
</xmltask>
<xmltask source="c.xml" dest="d.xml">
<attr path="/a/b" attr="id" value="${p}"/>
</xmltask>
will do what you want (I think). Sets the property 'p' to your text node.
Then the next <xmltask> uses this.
Note how the first <xmltask> only reads the document. It doesn't write it.
Hope this is of use.
