More XPath Functions
In addition to the XPath functions detailed in this chapter, here are some additional functions you might find useful. For a full list of the functions in XPath Version 1.0, see www.w3.org/TR/xpath#corelib.
x s l t <xsl:template match="history"> ... <xsl:value-of select="story"/> <br /><br />
Figure 4.23. To complete the output of the wonders-master.xml document, I add the story element to the History section. See Figure 4.23 below for a screenshot of the final HTML.

Node Functions:
- name(node-set) returns the first node in the specified node set, and name() returns the name of the current node.
- id(id-str) returns all the elements that have an ID equal to id-str.
String Functions:
- contains(str1, str2) returns True if str1 contains str2, otherwise returns False.
- string-length(str1) returns the number of characters in str1, while string-length() returns the number of characters in the current node.
- normalize-space(str1) returns str1 with all leading and trailing white space removed, and sequences of white space replaced with a single space. normalize-space() performs the same action on the current node.
Boolean Functions:
- not(expression) returns True if expression evaluates to False, and returns False if expression evaluates to True.
- | (a vertical bar; often located above the \ on your keyboard). Although it’s technically not a function, it is used to combine two node sets into one.
