Re: [xsl] Yet Another Entity Ref question!

[Marco Guazzone <sguazt@xxxxxxxxxxx>]

Hi David,
your idea is good.
Currently I'm using the LibXSLT processor version 1.0.23 (with libxml2
version 2..4.30).
However, with this I will produce the encode UNICODE char in the output
(HTML) doc; i.e.
XML:
<doc>
  <label>Foobar<entity>copy</entity></label>
  <entity-dict>
     <entity-item name="copy" value="&#169;" />
  </entity-dict>
</doc>

XSL:
<!-- ... like the previous except for: -->
<xsl:template match="entity">
  <xsl:value-of select="/doc/entity-dict/entity-item[@name =
current()]/@value" />
</xsl:template>

This produce as output
Foobar(C)Foobar(C)Foobar(C)
where (C) is the encoded value of &#169;
This may cause problem in non-UNICODE editors or browser, especially if I
include the result in a source document (e.g. Perl, C) as a return value
of a function (problems may arise in compiling/interpreting
phase).
Instead what I would generate is:
Foobar&copy;
or more generally:
Foobar&ent;
where "ent" is specified by an anonymous user in XML via:
<entity>ent</entity>
What do you think about it?
