Sorting On Multiple Keys
The first <xsl:sort ./> child specifies the primary sort key,

Introduction To XPath
Revise: an XPath location path is a series
of location steps that (conceptually) get us
from one point in an XML document to another.
If the location path begins with "/" it is
an absolute path, otherwise it's a relative
Conditional Processing With xsl:choose
Content: (xsl:when+, xsl:otherwise?)
<xsl:when test = boolean-expression>
The xsl:choose element selects one
Boolean Expressions In Predicates
These Boolean operators have their usual
meanings, and note that entity encoding will be
necessary for those containing "<" and ">":
eq lt gt
= < > <=
select = string-expression
"text" | "number"
"ascending" | "descending"
"upper-first" | "lower-
Can be used with <xsl:apply-templates .>, <xsl:call-template .> and <xsl:foreach .>
The xsl:message instruction sends a message. Displaying the content of the
message is dependent on the XSLT processor.
In Firefox the message is written to the Error Console.
<xsl:message terminate = "yes" | "no">
The XML Pointer Language is used to
identify abitrary locations inside an external
XML document. It can be thought of as an
extension to the HTML<a name="."/> "fragment
identifier" technique, but has advantages:
It's not necessary to have "modi
XPath defines a large-ish set of
useful functions. Functions return one of four
data types: Boolean, Number, Node-set and
String. Functions are indentified
by ( . ) parentheses on the end of the name.
These operate on, o
String Functions Reference
Converts its argument to a string. Booleans are converted to
"true" or "false", node-sets are converted to the string value of
the first node in the set (just like "xsl:value-of"), etc.
Returns true if the first string
