[xml] noob xpath question

There's likely a better list for this, but I've been spending most/all of my time at xmlsoft.org. I'm teaching myself xml, and I must be braindead - I just can't get past this one.

I've got xmllib2 compiled, and can compile and run a variety of the test code examples. I'm trying to get my head around xpath. Here is my toy xml file:

<?xml version="1.0" standalone="yes"?>
<!DOCTYPE myroot [
<!ELEMENT myroot (myelement+)>
<!ELEMENT myelement (x,y)>
<!ATTLIST myelement type (a | b) #REQUIRED>
        <myelement type="a">
        <myelement type="b">

Using the xpath1.c sample code, I can successfully find element nodes, but I can't "subselect" based on type. for example, this xpath:


returns 2 type nodes (as expected?), but no matter what syntax I've tried (I've googled, looked in books), I cannot select type a or b by itself, for example with umpteen variants of something along these lines:


I suspect I'm barking up the wrong tree (not to pun). Am I misusing xpath, probably on several levels? Have I missed a really dumb step in building the xml file to begin with? Other? Ultimately I want to be able to specify one element alone in the xml document using xpath - it's not so much that any final implementation will work like this... I just want to understand it.
