如何使用XPath根据其内容选择
XML节点？
如果我有以下xml,我想选择包含Ritchie的< author> -node来获取作者的全名：
<books>
<book isbn='0131103628'>
<title>The C Programming Language</title>
<authors>
<author>Ritchie,Dennis M.</author>
<author>Kernighan,Brian W.</author>
</authors>
</book>
<book isbn='1590593898'>
<title>Joel on Software</title>
<authors>
<author>Spolsky,Joel</author>
</authors>
</book>
</books>
/books/book/authors/author[contains(.,'Ritchie')]
要么
//author[contains(.,'Ritchie')]
