Martin,
Thanks for your response. I'm think I can get this done if I start modifying
struts, but I am looking for a simpler solution.
I am trying go dynamically create form elements based on a schema. I've been
using XALAN with FOP & came up with the idea that a tag could execute XALAN
& transform my schema into STRUTS tags. The issue is HOW to get the
generated STRUTS tags processed. An alternate solution is to build an editor
to edits the schema that regenerates portions of the JSP file. But this
would require redeploying the WAR, which isn't really a something we want
our customers doing.
In the following example, I have a schema named test.xsd. The
<app:databyschema> tag would examine the schema and generate the <struts>
tags, which would then render to HTML.
test.xsd
<xsd:schema xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<xsd:simpleType name="field1" base="xsd:string">
<xsd:minOccurs="1"/>
<xsd:maxOccurs="1"/>
<xsd:pattern value="([A-Z]){1,16}"/>
</xsd:simpleType>
<xsd:simpleType name="field2" base="xsd:string">
<xsd:minOccurs="1"/>
<xsd:maxOccurs="1"/>
<xsd:pattern value="([A-Z]){1,16}"/>
</xsd:simpleType>
So the tag: <app:databyschema schema="test.xsd"/>
is processed and returns
<struts:text property="field1" size="16" maxlength="16"/>
<struts:text property="field2" size="16" maxlength="16"/>
which is then processed to HTML.
I'm keeping a close eye on this thread & if/when I find a solution I'll post
it.
Thanks for all the responses.
Wayne

Actually, the <logic:iterate> tag doesn't produce tags, although it does
iterate over the tags in its body.
What Wayne wants to do, as I understand it, is have a tag that can actually
generate some JSP containing other tags (in this case Struts tags). Those
tags would then be evaluated, and may in fact produce yet more tags, and so
on until there were no more tags to process.
My guess now, after Nick Pellow pointed out the bug in my thinking (thank
you, Nick! :-) ), is that you just can't do this, at least not this way.
Wayne, can you tell us what it is you're trying to do? Maybe we can come up
with an alternative approach.
