RE: HELP ME! Getting xml filename and node path from diffrent xml doc ument.

["Carlberg, Anders" <Anders dot Carlberg at infologigruppen dot se>]

Hi Oliver.

First, Thanks for your reply.

Here a are a example.
First document contains this:
(doc1.xml)

<xml>
	<textbox>
		<name>name</name>
		<value>/xml/adressbook/entry/name</value>
	</textbox>
</xml>


Second documnet:
(doc2.xml)

<xml>
	<adressbook>
		<entry>
			<name>Anders Carlberg</name>
		</entry>
	<adressbook>
</xml>



Note that the value text() in doc1.xml is the "path" to the name in
doc2.xml.
My question is. How can i use a xsl to get a result that would look somthing
like this.
<xml>
	<textbox name="name" value="Anders Carlberg" />
</xml>

What im looking for is a way to read the "path" in doc1.xml and use it to
get the value from
doc2.xml. This is my problem.

Im using Xalan today, but it dosen't matter what i use.
(Xalan implements xsl and xpath spec i think).
I havent used saxon at all, so im going to take a look now.


Cheers
/Anders

It's a little bit difficult to guess what your documents actually look
like. Maybe an example would be very helpful.

It's no problem to open and read an other XML document via the
document function. The parameter (the file name) can be obtained
from your XML source.

Your second question seems to be more problematic.
Am I right in assuming that the XPath expression is part of your
XML source?

Something like
<root>
   <expression path="/foo/bar[@att='value']" />
</root>

XSLT doesn't have a facility to evaluate XPath expressions dynamicly,
i.e. they must be a static part of the stylesheet.

The Saxon processor provides an extension function saxon:evaluate()
that closes this gap.

Hope this helps,
Oliver
