foreach with XMLTool
I have an XML document of the form
<data>
<details>
<row>
<item1>
<item2>
</row>
<row>
<item1>
<item2>
</row>
</details>
</data>
I cannot seem to find a way to successfully iterate over the row elements. For some reason the data from each of the rows is being co-mingled. Does anyone have an example of iterating over xml elements using the XMLTool?

I suspect the solution is going to require changing get() to do
if (s.indexOf('/') < 0)
{
s = "./" + s;
}
instead of
if (s.indexOf('/') < 0)
{
s = getPath()+'/'+s;
}
I'm not sure why it makes sense to have get always start at the root instead of at the current node.

Hmm. Sounds less than ideal. I don't have time to improve how the
XMLTool handles this, but if you're up for filing a bug and perhaps
even contributing a patch, that'd be great. :)

I found that the problem isn't in the foreach. It is that when you do
#foreach($row in $xml.details.row)
$row.item1
#end
It results in item1 printing the item1 value for all rows. This is because get() calls find("item1") which then calls node.selectNodes() in dom4j. dom4j returns all the the nodes. The only way I have found to fix this is to do
$row.find("./item1")
This returns the value for only the current row.
