I *think* that you're after unparsed-entity-uri(). For example, if I
have the following XML file:
--- test.xml ---
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="test.xsl" ?>
<!DOCTYPE image [
<!NOTATION GIF SYSTEM "gif.doc">
<!ENTITY logo SYSTEM 'logo.gif' NDATA GIF>
<!ELEMENT image EMPTY>
<!ATTLIST image
source ENTITY #IMPLIED>
]>
<image source="logo" />
---
The 'img' element I want to create has a 'src' equal to the file
location of the 'logo' entity. In other words, I want to create
something like:
<img src="logo.gif" />
Getting the file location of the logo entity involves:
unparsed-entity-uri('logo')
or, given you want to get this from the 'source' attribute of the
image:
unparsed-entity-uri(/image/@source)
To put that value into the 'src' attribute of an 'img' element, use
either xsl:attribute:
<img>
<xsl:attribute name="src">
<xsl:value-of select="unparsed-entity-uri(/image/@source)" />
</xsl:attribute>
</img>
or an attribute value template:
<img src="{unparsed-entity-uri(/image/@source)}" />
I hope that helps,
Jeni
