I've been using the XML tags in JSTL and found them very useful, however now I need to add an attribute to an XML element and have hit a brick wall.
I've tried using <c:set> and EL, treating a DOM object as a bean, but the DOM interface is implementation-dependent and my implementation (xerces) doesn't lend itself to adding attributes with the simple EL view of bean properties.
It seems to me that <x:set> needs to have a "target"attribute along the same lines as <c:set>, but accepting an XPath expression.
eg
<x:set select="12345" target="$myRoot//myElement[position()=0]/@myAttribute" />
where:
- select can be either an XPath expression or an immediate value.
- if @myAttribute doesn't currently exist in the element then it is created.
Does this make sense?
Is there a simple, portable, way of achieving this using JSTL as it stands? (Using <c:set> is not portable due to DOM being implementation dependent).
Thanks Murray
