The <xsl:value-of> element is used to extract the value of a selected node.
The <xsl:value-of> element can be used to extract the value of an XML element and add it to the output stream of the transformation:
Note: The select attribute, in the example above, contains an XPath expression. An XPath expression works like navigating a file system; a forward slash (/) selects subdirectories.
The result from the example above was a little disappointing; only one line of data was copied from the XML document to the output. In the next chapter you will learn how to use the <xsl:for-each> element to loop through the XML elements, and display all of the records.
