Using RTEs in attribute values in XML JSPs
Hello,
I've been reading archived struts-user emails but haven't been able to
solve this problem to my satisfaction.
I have a JSP, written using the XML JSP syntax, that outputs XML. I want
to use a run-time expression (RTE) inside a Struts 1.0.2 <logic:iterate>
tag, for example:
<!-- %= listitem.getString() % does not get evaulated in this example -->
<logic:iterate id="listitem" name="list" type="foo.struct" scope="request">
<image xlink:href="%= listitem.getString()%"/>
</logic:iterate>
<!-- Here, listitem.getString() gives the expected value from the bean,
but I can't use <jsp:expression>
to assign an attribute's value in an XML-syntax JSP without getting the
error "
The value of attribute "xlink:href" must not contain the '<' character.
" -->
<logic:iterate id="listitem" name="list" type="foo.struct" scope="request">
<jsp:expression> listitem.getString() </jsp:expression>
</logic:iterate>
I hope I am just missing some simple escape sequence, but I've tried
various ideas and haven't gotten lucky. My workaround is:
<!-- Works, but... Yuk! -->
<logic:iterate id="listitem" name="list" type="foo.struct" scope="request">
<jsp:scriptlet>
out.write("<image xlink:href=\"" + listitem.getString() + "\"/>");
<jsp:scriptlet>
</logic:iterate>
Can anyone tell me a better way? I haven't tried to use a RTE to assign
outside of the struts iterator. I'd really like to avoid adding any
other taglibs to my app. if possible. Do I need struts 1.1?
Thanks,
Cindy

Re: Using RTEs in attribute values in XML JSPs
Posted by "Craig R. McClanahan" <cr...@apache.org>.
My bet is that you'll find the traditional JSP syntax more palatable for
hand authored pages -- even those that ultimately render XML content. The
XML syntax is designed to be consumed by tools, and isn't really very
human friendly.
