How to asign a value to a variable??
Hi!
I want to define a global variable with no value.
Then I want to asign a value to the variable in a choose-when-select.
I think of something like this (but this one doesn't work):
<xsl:variable name="element" />
<xsl:for-each select="*">
<xsl:choose>
<xsl:when test="local-name() = 'rettungswege'">
<xsl:variable name="element" select="rettungswege/rw" />
</xsl:when>
<xsl:when test="local-name() = 'trennwaende'">
<xsl:variable name="element" select="trennwaende/trennwand"
/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
<xsl:for-each select="$element">
...do something...
</xsl:for-each>
Is this possible?
Thanks,
Barthi

Nope, sorry!
"Variables" in XSLT aren't reassignable, so once you create a variable its
value is set. In this way the term "variable" is a bit of a misnomer.
There are probably other ways besides reassigning variables to accomplish
what you're trying to do though. Your best bet would be to post to an
XSLT-related mailing list as that's where you're going to find the most
experts able and willing to help you out.

How to process Dom Object from Form Binding
Posted by Pe...@gmx.net.
Hello,
I would like to further process the xml data from my cform in another
pipeline. I saw in the samples that it's possible to build a
dom object. But I saw the tree is directly written to file.
I my case I need to further process the data so I don't want to do an file
operation. How can I do that?
The code I'm refering to is below:
var doc =
Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
doc.appendChild(doc.createElement("project"));
form.createBinding("bind.xml");
form.save(doc);
cocoon.sendPage("some-pipeline-for-postprocessing-xml",
{, document: doc}
cheers,
Pete

No, because that's not how variables work in XSL. Once they're assigned
they're visible at that level and below, and you can't change them. You
have to use something structured more like
<p>Try visiting<ul>
<xsl:for-each select="tutorial">
<xsl:variable name="foo">
<xsl:choose>
<xsl:when test="@id = '1'>
http://www.topxml.com/xsl/tutorials/intro/default.asp
</xsl:when>
<xsl:when test="@id = '2'>
http://en.wikipedia.org/wiki/XSLT
</xsl:when>
<xsl:otherwise>
http://www.jenitennison.com/xslt/
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<li><xsl:value-of select="$foo"/></li>
</xsl:for-each>
</ul></p>
This isn't really a Cocoon issue, though, and there are plenty of dedicated
XSL sites and mailing lists...
Andrew.
