passing a space

[David Schwartz]

I have a template that searches for and replaces found instances of
strings in other strings and replaces them with yet another string.
These strings are passed to the template as parameters, not
surprisingly. It so happens at the moment that I need to replace
instances of spaces with a plus sign. Unfortunately, I don't know how
to pass a space effectively, the template just doesn't get it.

Any thoughts re how to fix this would be appreciated!

TIA,
David

Hi David,

You are not saying how you pass the parameters... Are you passing them
from a call-template instruction?
In that case I do not see the difficulty with that, just enclose the
space in apostrophes if you put that in the select attribute.

<xsl:with-param name="p" select="' '"/>

Regards,
George

Are you passing them from a call-template instruction?

Yes, that's how they're being passed but when I use this syntax,
<xsl:with-param name="p" select="' '"/>, I get an 'Empty expression'
error from the processor (XALAN). Isn't the 'select' attribute
reserved for nodes? I've been using "<xsl:with-param name="p"</
xsl:with-param>" to no avail.

No.

I've been using
"<xsl:with-param name="p"</xsl:with-param>" to no avail.

Works just fine for me with xsltproc, Saxon-8B, xalan-c++:

pavel@debian:~/dev/xslt$ a param_space.xsl
<xsl:styleshe et version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
<xsl:call-template name="named">
<xsl:with-param name="str" select="' '"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="named">
<xsl:param name="str"/>
<result>
<xsl:value-of select="$str"/>
</result>
</xsl:template>
</xsl:stylesheet>

Perhaps the problem lies elsewhere. Try reproducing it in a
minimum possible transformation.

When I use <xsl:with-param name="p" select="'e'"/(for testing
purposes, NOTE: NOT a space), I get the following result:

JVMDG217: Dump Handler is Processing Signal 11 - Please Wait.
JVMDG303: JVM Requesting Java core file

\javacore.20071 008.081548.7900 .txt
JVMDG215: Dump Handler has Processed Exception Signal 11.

When I use <xsl:with-param name="p">e</xsl:with-param>, it works like
a charm.

FYI, I'm using XALAN v.2.7.0.

As others have said, this should work.

This *won't* work, because of whitespace stripping. Add an
xml:space="pres erve" attribute to the xsl:with-param element.

Or use
<xsl:with-param name="p"><xsl:t ext</xsl:text></xsl:with-param>

Good catch; I wasn't reading that closely.
