xsl = etree.XML(dedent( """<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dp="http://www.datapower.com/extensions" extension-element-prefixes="dp">
<xsl:template match="node()|@*"> xsl:copy <xsl:apply-templates select="node()|@*"/> </xsl:copy>
<xsl:variable name="destination_url"> <xsl:value-of
select="'https://my.domain.example.com/'" />
</xsl:variable>
<!--Set the destination URL in the context variable--> <dp:set-variable name="'var://context/mpgw/Destination'" value="$destination_url" />
I don't think I've ever tried this myself in lxml. I guess I would have expected value="{$destination_url}" rather than the plain variable reference here. Can't say how XSLT is meant to deal with this.
Just for the record: Like Stefan suspected the way to dereference a variable in XSLT here is value="{$destination_url}".
I.e. such stylesheet
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:variable name="my_var" select="'my value'"/> <xsl:template match="@*|node()"> <foo attr="$my_var">bar</foo> </xsl:template> </xsl:stylesheet>
yields
<?xml version="1.0" encoding="UTF-8"?><foo attr="$my_var">bar</foo>
whereas
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:variable name="my_var" select="'my value'"/> <xsl:template match="@*|node()"> <foo attr="{$my_var}">bar</foo> </xsl:template> </xsl:stylesheet>
yields
<?xml version="1.0" encoding="UTF-8"?><foo attr="my value">bar</foo>
Boy, am I getting rusty :-)
