New line 
 does not work with lxml parser

dved · February 19th, 2009, 03:17 PM

I m using lxml parser to insert my XSL to the generated XML.

Its works well except for the fact that i defined NL as 
 and it does not give me new line when I try it with lxml parser..

it works great when i m using my oxygen editor with saxon...

Is there different interpretations ??

lxml as I understand it is a Python front-end to libxslt. Libxslt is usually pretty conformant.

I think you need to post a small but complete code example, and show the results you get with both processors.

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE xsl:stylesheet [

<!ENTITY NL "<xsl:text>
</xsl:text>">

]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" encoding="utf-8" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>
<xsl:strip-space elements="*"/>
<xsl:template name="header">
<xsl:text>MTN| </xsl:text>
&NL;
</xsl:template>
<xsl:template match="lertDVSResults">
<xsl:call-template name="header"></xsl:call-template>
<xsl:apply-templates select="Data/searchItem/DVSResult"></xsl:apply-templates>

</xsl:template>
<xsl:template match="serviceResponse//child::feature">
<xsl:call-template name="getFeature"></xsl:call-template>

</xsl:template>
<xsl:template name="getFeature">
<xsl:value-of select="ancestor::searchItem/child::value" />
<xsl:value-of select="'|'"/>
&NL;

</xsl:template>
</xsl:stylesheet>

The output of this XSL in Saxon6.5.5 is:
MTN|
123-123-1231|
234-234-2341|
..
.....

But what I get when I use lxml is:
MTN|123-123-1231|234-234-2341|....

Here is a bit of python part:
runner_service = self.DefinedServices[param_type][self.call_type]
xslt_doc = ET.parse(runner_service[1])
transform = ET.XSLT(xslt_doc)
call_list = runner_service[0]
### Placeholder for complete aggreagated XML results
complete_dvs_results = ET.XML("<lertDVSResults><CallType>%s</CallType><Data></Data></lertDVSResults>" % self.call_type)
return self.saveFile(str(transform(complete_dvs_results)) )

I can not write the whole python but its just simple..dont do much there except applying transform to the file..

thanks

That certainly looks wrong to me. Raise a bug report with the product supplier.
