XML/XSL newb q: can I ever select or refer to xml attribute values?

[5tein]

I mean, with XSL functions such as SELECT can I only refer to XML element values or can I somehow also refer to XML attribute values? Is there any way to refer to XML content based on attribute values? Or is it a parsed data only thing?

BTW, new to XML; sorry if this is a dumb question. I just haven't seen this explicitly stated anywhere (though by experience it doesn't seem to work).

I hate it when people as questions in the subject line, then don't repeat them in the body of the message.

Select isn't a function -- rather it's an attribute of several elements. This attribute always contains an xpath expression, so you can refer to anything xpath can refer to.

As it happens, you can refer to attributes. It's worth reading an introduction to xpath, but you can do something like

<xsl:value-of select='@x'/>

to get at the value of attribute x of the current node.
