Extracting information from XML

Hello,

I'm trying to extract information from some XML files, but I'm 
encountering a couple of unusual cases (below).

Any suggestions are welcome.

Lots of thanks,
Eric.



Question 1.

We want to extract "hyphenated-name" nodes from some XML:-

<root>
     <hyphenated-name data="first"/>
     <hyphenated-name data="second"/>
</root>

I would like to use
     <#list document.root.hyphenated-name as node>
but the hyphen prevents this from working. None of these work either:-
     <#list document.root."hyphenated-name" as node>
     <#list document.root.'hyphenated-name' as node>
     <#list document.root.`hyphenated-name` as node>

I ended up using
     <#list document.root?children as child>
       <#if child?node_type = 'element' && child?node_name = 
"hyphenated-name">

Are there better options?




Question 2.

How should I extract an attribute from an XML node, when the name of the 
attribute is given by a variable?
e.g. is there something like ${node.@$attrName}


Here's my XML:-

<root>
     <attr name="a" />
     <attr name="b" />

     <data b="B" a="A" />
</root>


I tried

<#list document.root.data as data>
   <#list document.root.attr as attr>
     ${data.@$attr.@name}
   </#list>
</#list>

but this caused
SEVERE: javax.xml.transform.TransformerException: A node test that 
matches either NCName:* or QName was expected.

A bug?
