!!! NEED HELP for Passing request parameters - and making use of them in the XSL
I want to do that too but then with XPath. I want to transform my Xpath
results into HTML.
In IExplore I go to an URL which contains xpath parameters. Then when I don't
put in a transform or anything like that I just get a page in XML with the
results of my query. In that case XPath has added a couple attributes to the
result like the locations and the filenames of the results. I need that
information for my stylesheet.
Now I need to transform that automatically into HTML. But I have no idea how
to do that. I tried just using a transform but if I do that it shows the
stylesheet without the XML page I had without the transformation. So the
result table I made in the stylesheet is shown but there's no data in it.
I can't just pass the XPath parameters that only contains my query and I need
the results to. Or can I do that some way?
Can anyone help because I need to solve this very badly, thanx

RE: !!! NEED HELP for Passing request parameters - and making use of them in the XSL
Posted by Conal Tuohy <co...@paradise.net.nz>.
Lenya's example is correct AFAIK:
<map:match pattern="archives/**">
...
<map:transform src="my.xsl" type="xslt">
<map:parameter name="param" value="{1}">
</map:transform>
...
</map:match>
In the XLST:
...
<xsl:param name="param"/>
---
<xsl:value-of select="$param"/>
Note the $ in the value-of expression (I think this is Lenya's mistake -
<xsl:value-of select="param"> will refer to a probably non-existent <param>
element, and return an empty string).
AFAIK you can't really use an XPath expression passed this way. The XSLT
parameter will be a string, and there's no way to evaluate that as a kind of
macro in XSLT. If your XPath expression was always in some simple format
like "id('foo')" or "/foo[1]/bar[3]/baz[2]" it would be easy to parse, but
for general XPath you don't want to parse it in XSLT!!!
You could try using the XIncludeTransformer, or the XPathTransformer in
Forrest, more like it.
