[xsl] Evaluating condition strings
Hi!
I've got a XML doc which contains a description of a final document.
This XML doc uses tags that handle conditions:
<if condition="var1 = true or var2 < 5 and var3 = 'ok'">
<then>
text
</then>
<else>
another text
</else>
</if>
the variables are available in another XML doc:
<attributes>
<variable name="var1">false</variable>
<variable name="var2">4</variable>
<variable name="var3">ok</variable>
</attributes>
I think I could evaluate the conditions by writing an extension for the
xslt processor (I'm using Xalan-J) or parsing the conditions before the
transformation process (maybe with a dynamic language like groovy
because the variables are not typed.).
Could it be done with pure XSLT? What approach would you recommend?
TIA
Martin
