xsl_include href="$include_file" - doesn't evaluate parameters

[greg keraunen <gk...@valinux.com>]

Is this a bug or a feature?
The normal param usage, <xsl:value-of select="$param_name"/>  doesn't
seem to apply for assigning values to attributes inside the xsl:include
element.

Code:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:h="http://www.w3.org/TR/REC-html40">

<xsl:output indent="yes"/>

<xsl:param name="include_file">/home/greg/xslt/test1.xsl</xsl:param>

<xsl:include href="$include_file" />

</xsl:stylesheet>

Gives the following error:
XSLT: File "file:/home/greg/xslt/$include_file" not
found.                                                                                                                                                                           

As you can see, $include_file is being taken literally as the value of
the url rather than evaluating the parameter first.

In another posting (which foolish me deleted already) you said it's just
for the purpose of not hard-coding the filename in several stylesheets.
Why not use "good old" XML external entites for that purpose?

Example:

-- file "sheet.xsl"

<?xml version="1.0"?>
<!DOCTYPE xsl:stylesheet [
 <!ENTITY % common SYSTEM "common.ent">
 %common;
]>
<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
    <xsl:include href="&filename;"/>
</xsl:stylesheet>

-- file "common.ent"

<!ENTITY filename "somefile.xsl">


This way you can put everything that should be shared between your
stylesheets in "common.ent".

Regards

  Andreas
