The Path to an Element

---

Finding Element Contents

Listing A.3 displays the contents of the XSL stylesheet titleAndAuthor.xsl that extracts the title and author of the book in the file book.xml.

Listing A.3 titleAndAuthor.xsl

<?xml version="1.0"?> <xsl:stylesheet      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"      version="1.0"> <xsl:template match="/">   <xsl:value-of select="./book/title"/> by   <xsl:value-of select="./book/author"/> </xsl:template> </xsl:stylesheet>

Remarks

Listing A.3 matches the following two items in book.xml:

<book>   <author>Oswald Campesato</author>   <title>SVG Programming</title>   .... <book>

The full paths /book/author and /book/title specify the author and title, respectively, which match in the first template. Note that the concatenation of the root node '/' with the path '/.book/title' is '/./book/title,' which resolves to the path '/book/title.' Similarly, the concatenation of '/' and './book/author' is '/./book/author,' which resolves to the path '/book/author.'
