Accessing Node Values

Accessing Node Values

The <xsl:value-of> element writes the string value of an expression to the result document; in particular, you can use it to return the value of a node, which, for an element, is the elements enclosed text.

You can assign the <xsl:value-of> elements select attribute an XPath expression that specifies a node or node set. When youre in the template that matches <PLANET> elements, you can use the XPath expression "child::MASS" to refer to the <MASS> child element. As youll see in Chapter 4, you can abbreviate XPath expressions in a number of ways, and in particular, "child::MASS" can also be written simply as "MASS" . That means you can recover the data from the child elements such as <MASS> , <DAY> , and so on in this way:
