I want to perform a series of operations on elements that matched the name "A" or "B". I'm thinking of something like this below, but it doesn't work.
<xsl:template match= " 'A' or 'B'" > <!-- whatever I want to do here --> </xsl:template> Couldn't find the appropriate XSLT language reference for it. Please help! Thanks!!

The match attribute is used to associate a template with an XML element. The match attribute can also be used to define a template for the entire XML document. The value of the match attribute is an XPath expression (i.e. match="/" defines the whole document).
The XPath expression @* | node() selects the union of attribute nodes ( @* ) and all other types of XML nodes ( node() ). It is a shorthand for attribute::* | child::node() .
The regex-group() function names which matched string you want to use inside of the xsl:matching-substring element; pass it a 1 to get the first, a 2 to get the second, and so forth. The example above uses it to plug the three matched values inside new city, state, and zip elements created for the output.
A <! -- --> comment can be produced in the output with the comment element. The content of the comment element is used as the contents of the output comment. Literal comments in a template are assumed to be a comment for the XSLT stylesheet, and are ignored, so a comment in the output can't be produced that way.
Try this:
<xsl:template match= "A | B" > See this page for details.

Generally A | B is the right way to do this. But the pipe character is basically a union of two complete XPath expressions. It can be annoying to use it in a case like this:
/red/yellow/blue/green/gold | red/orange/blue/green/gold since you're repeating the entirety of the expression except for the one small piece of it's that changing.
In cases like this, it often makes sense to use a predicate and the name() function instead:
/red/*[name() = 'yellow' or name()='orange']/blue/green/gold This technique gives you access to a much broader range of logical operations. It's also (conceivably) faster, as the XPath navigator only has to traverse the nodes it's testing once.
