This sounds interesting. Maybe we would want to introduce some
xpathselection elements to replace your property example. Properties in this
example would probably be a little confusing to the user since it isn't
really a regular property (the value is retrieved via xpath, not only via an
expression).
<xmlforeach file="" xpath="">
<xmlselect propertyname="" xpath="@attribute">
<xmlselect propertyname="" xpath="node">
<xmlselect propertyname="" xpath="text()">
<xmlselect propertyname="" xpath="child/@attribute">
<do>
...
</do>
</xmlforeach>
It would be really cool if we make this work so that you could use the
<xmlpeek/> task to select from the open file (xmldocument). Then later when
if/when we get referencable types (for example an xml file factory or
something) we could just a little more efficient. It would be nice to use
the implied context here to simplify things.
;)
<foreach /> could also be updated but this probably falls out of the scope
of that. This is pretty specialized, and will need to be very specific to
xml.
