Message: <blockquote data-quote="reanjr" data-source="post: 2147831" data-attributes="member: 20740">As to the first point, there is a way to do it (and I suppose it could be mashed into a function, too; but I hadn't gotten to anything like that yet).  Basically, the <a> function can resolve simple XPath like statements and return arrays of data.  For instance:<a>feats.feat:type='Fighter'</a>Would return an array of all feat elements that are children of the feats element and half a type attribute set to Fighter.  Once you have this array, you can use another special resolution mechanism ::Say that you store the array in a variable called fighter-feats.  Then:<a>fighter-feats::count</a>Would return the number of elements in the array<a>fighter-feats::1</a>Would return the first of them.So you could fairly easily write a foreach function (and I'm pretty sure I will).I haven't finalized anything on the way those variable resolutions work yet, but tentatively, the following apply:[CODE].Current context.childThe child of the current context (and so forth like .child.grandchild etc.)  This can be a child element or a property of the context.:propertyA property.  If this is left without any qualification, it just checks if the property exists or not.  You can also append ='value' to evaluate to a property that is set to a particular value.  I use single quotes here for ease of parsing.  Unlike using the .child syntax to select a property, using the :property syntax doesn't evaluate to the property but is used as a means of identifying elements.  (I hope I explained that clearly, I can't tell).::countThe number of elements in the reference.  Usually 1.::1, ::2, etc.A particular element if there are multiple.  Defaults to the first element if unspecified.[ ]Anything found in brackets is evaluated as a variable reference then plugged in to its surroundings (<a>fighter-feats::[counter]</a> for instance).[/CODE]</blockquote>
