Xml+XSL: Problems with FireFox displaying

[Jesper Stocholm]

I have som XML that link to an XSL-file to enable on-the-fly HTML-generation by e.g. IE or FireFox. The transformation actually works like a charm, but I have problems with changing line breaks in the XML to their html-equivilant <br/>.

I use the XSL:

<xsl:template name="break">
<xslaram name="text" select="."/>
<xsl:choose>
<xsl:when test="contains($text, '
')">
<xsl:value-of select="substring-before($text, '
')"/>
<br/>
<xsl:call-template name="break">
<xsl:with-param name="text" select="substring-after($text,' ')"/> </xsl:call-template> </xsl:when> <xsltherwise> <xsl:value-of select="$text"/> </xsltherwise> </xsl:choose> </xsl:template>

And I apply it to the specific XML-element with the code

<xsl:call-template name="break">
<xsl:with-param name="text" select="description"/>
</xsl:call-template>

When I display the XML-file in IE, it all looks fine and dandy - but when I load the page in FireFox (1.0 PR), the linebreaks are not converted to html-<br>-tags.

What am I doing wrong?

And - are there some programs out there that will allow me to supply a XML-file and a XSL-stylesheet - and then display the result of the XSL(T)-transaformation?

Hard to tell, maybe you can post the URLs of a short XML sample and XSLT demonstrating the problem. I see nothing wrong in that XSLT snippet you have above but the problem could be with your XML input.

When displayed in IE the result is as expected - but not in FireFox

You are transforming to XHTML but inside that template you call the <br/> elements are in the null namespace so make that

<xsl:template name="break">
<xslaram name="text" select="."/>
<xsl:choose>
<xsl:when test="contains($text, '
')">

<xsl:value-of select="substring-before($text, '
')"/>
<br xmlns="http://www.w3.org/1999/xhtml" />
<xsl:call-template name="break">
<xsl:with-param name="text" select="substring-after($text,' ')"/> </xsl:call-template> </xsl:when> <xsltherwise> <xsl:value-of select="$text"/> </xsltherwise>

</xsl:choose>
</xsl:template>

and it should work.

By the way, to output a DOCTYPE node you shouldn't use disable output escaping but rather the <xslutput> element.

aah ... )

<xsl:template name="break">
<xslaram name="text" select="."/>

<br xmlns="http://www.w3.org/1999/xhtml" /> <xsl:call-template name="break"> <xsl:with-param name="text" select="substring-after($text,' ')"/> </xsl:call-template> </xsl:when> <xsltherwise> <xsl:value-of select="$text"/> </xsltherwise>

</xsl:choose>
</xsl:template>

and it should work.

It did, thanks.

Ok - I see your point. I changed it to

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xslutput
doctype-public="-//W3C//DTD XHTML 1.1//EN"
doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" encoding="ISO-8859-1" method="html" />

And the above now also looks as intended in FireFox.

Thanks for your help and have a nice weekend,

If you have a recent version of IE, you probably have MSXML somewhere on your system, if you can figure out how to use it.

Or you can use either of these two open-source XSLT processors

Saxon: http://saxon.sourceforge.net/ (Java based)
Xalan: http://xml.apache.org/xalan-j/ (Java version) or http://xml.apache.org/xalan-c/ (C++ version)

If you're looking for something that is free. Try jEdit. I know several people that like Eclipse and XMLBuddy as well. XMLSpy and StyleStudio are both good commercial products that will perform XML/XSLT transformation. The Xalan package has a simple XSTL transformation example that works fine from a command line.

I bet I can - I have used it before, I just seem to remember a command-line tool I once used to test xslt-transformation.

I will look at the above - or write a small test-harness in C#.

Thanks,
