XSL:VALUE-OF
I have a template say, columnHeader which i am calling as below in a xsl:
<xsl:call-template name="columnHeader">
<xsl:with-param name="value"><a id="frameLoader"
href="javascript:void(0);" onclick="javascript:<xsl:value-of
select="$gridName"/>.expandAllTreeRows(this);">+</a></xsl:with-param>
</xsl:call-template>
Inside the template apart from other stuff, i print the value using
xsl:value as below:
<xsl:value-of select="$value"/>
This code was working fine before migrating to Xalan 2.7.1. But, once i
moved to Xalan 2.7.1, text in the value variable is getting printed as
normal text, it's not being treated as html and hence not being rendered as
a href in the browser. Instead i get something like javascript:void(0); +
as plaint text.
Please suggest.

That's plain wrong. You're falling back to your initial mistake.
I suggest you reread the answers Christoffer and I gave you. Or
read a good book on XSLT to overcome wrong concepts you seem to
have acquired.

Hi Chris,
Problem hear is i can't use '<a' as i have a onclick attribute on href which
takes value from '<xsl:value-of select="$gridName"/>', so i used '<' and
'>'. But, giving these making it considered as normal text instead of a
node.
thanks,
ravi.

Hi Chris,
I tried both ways, but the same result, only text is being written.

Hi mahati,
I believe you must write: <a id="frameLoader" ......>+</a>
Instead of : <a id="frameLoader" ...>+</a>
Otherwise you do not create an element in the result tree, but only a text.

Re: XSL:VALUE-OF

Following is a param to a template
<xsl:with-param name="value"><a id="frameLoader"
href="javascript:void(0);" onclick="javascript:<xsl:value-of
select="$gridName"/>.expandAllTreeRows(this);">+</a></xsl:with-param>
Then, within the template, i have:
<xsl:copy-of select="$value"/>
This makes template to print:
javascript:void(0); +
But, the problem is that browser just prints this as raw text instead of
interpreting as href element.
You can observe that entire output is being captured correctly but gets
printed as raw text instead of being treated as html.
thanks,
mahati.

That doesn't make sense. <xsl:copy-of select="$rtf"/> should copy the
RTF to the output. Could you post an example?

Xalan doesn't know about tags, it knows about element nodes. I don't
think <a> elements are treated specially.

I think I've already suggested a solution. Does it not work?

Re: XSL:VALUE-OF

Thanks Michael. Yes, a tags are shown in the text, but posted text doesn't
have them.
I found that + is getting printed due to a separate piece of code within the
template, not due to 'value' parameter.
I tried using xsl:copy-of, but it's printing html as raw text to the
browser, same as my original problem that i posted in the first post on this
thread.
Requirement here is to build a href dynamically and show it. Do you mean 'a'
tag is ignored by Xalan 2.7.1, by the way, this problem is showing up only
after we migrated to 2.7.1.
Please suggest.

This differs from your original example. You're missing the <a> element.
(Maybe it got eaten in the mail processing chain.) Xalan-J 2.7.1 and
LibXSLT 1.1.24 both ignore this attribute. Saxon 6.5 issues a warning:

I suggest you adjust your code.
By the way, if you pass the parameter as you intend it to appear in the
output, spare yourself the hassle of exsl:node-set() plus identity
transform and use <xsl:copy-of> as in the following example.
In addition, use literal XML for the parameter instead of constructing
it using <xsl:attribute>. That's much more readable. Use the latter
method only if dynamic computation of the attribute name is required.

Thanks Chris.
I have tried your sugesstions. Now, i could see that only + gets printed but
not href tag around it. Here's the changes i have done. '+' is supposed to
be label of the href.
<xsl:call-template name=columnHeader">
<xsl:with-param name="value">
<xsl:attribute name="id">frameloader</xsl:attribute>
<xsl:attribute name="href">javascript:void(0);</xsl:attribute>
<xsl:attribute name="onclick">javascript:<xsl:value-of
select="$gridName"/>.expandAllTreeRows(this);</xsl:attribute>
+
</xsl:with-param>
</xsl:template>
and in the template i have used,
<xsl:apply-templates select="exsl:node-set($value)" mode="identity"/>
along with
<!-- an indentity transform scoped by a specific mode - so that it is not
accidentally run-->
<xsl:template match="@*|node()" mode="identity">
<xsl:copy>
<xsl:apply-templates select="@*|node()" mode="identity"/>
</xsl:copy>
</xsl:template>
Please suggest.

Hi mahati,
I think you should create a resulttree fragment containing the <a> tag
instead of trying to print it as text.
I would suggest doing something like :
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"
xmlns:exsl="http://exslt.org/common">
<xsl:call-template name=columnHeader">
<xsl:with-param name="value">
<a>
<xsl:attribute name="href">javascript:void(0);</xsl:attribute>
<xsl:attribute name="id">frameloader</xsl:attribute>
...
</a>
</xsl:with-param>
</xsl:call-template>
<xsl:template name="columnHeader">
<xsl:param name="value"/>
...
<!-- now print the fragment -->
<xsl:apply-templates select="exsl:node-set($value)" mode="identity"/>
...
</xsl:template>
<!-- an indentity transform scoped by a specific mode - so that it is
not accidentally run-->
<xsl:template match="@*|node()" mode="identity">
<xsl:copy>
<xsl:apply-templates select="@*|node()" mode="identity"/>
</xsl:copy>
</xsl:template>
Best regards,
Christoffer Bruun
