[Expat-discuss] entities in parameters

[Lee Brown]

I see a different behavior after upgrading from expat 1.95.2 to 1.95.8 and using the library with Sablotron's sabcmd XSL translator.  A picture is clearer....

XSL:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>

<xsl:param name="LF"><xsl:text>&#xa;</xsl:text></xsl:param>
<xsl:param name="AA">LINE: </xsl:param>

<xsl:template match="/test">
        <xsl:for-each select="line">
                <xsl:value-of select="$AA"/>
                <xsl:value-of select="."/>
                <xsl:value-of select="$LF"/>
        </xsl:for-each>
</xsl:template>
</xsl:stylesheet>

XML:

<?xml version="1.0"?>
<test>
<line>line one</line>
<line>line two</line>
<line>line three</line>
</test>

With the 1.95.2 library I get line-breaks between each line in the XSL translation output, but with the 1.95.8 library there are no line-breaks.  The AA parameter does get expanded, so I'm certain this has to do with entities.  If I replace the "$LF" in the xsl:value-of element with "'&#xa;'" then I do get a line-break.  The behavior is the same if I use xsl:variable instead of xsl:param.  I've also tried the example with saxon instead of sabcmd (saxon does not use the expat library) and I do get line-breaks.

Can anyone shed any light on this?

P.S. I'm running on UnixWare 2.1.3.  I built from source, no modifications necessary.

Thanks,
Lee
