XPath stands for XML Path Language, it uses a non-XML syntax that provides a flexible way of addressing (pointing to) different parts of an XML document. As well as this, it can also be used to test addressed nodes within a document to determine whether they match a pattern or not.

    XPath代表XML Path Language。它使用一种与XML不同的语法,可以灵活的在XML文档中寻找节点,同时它也可以用来测试某些节点是否满足格式要求。

    XPath is mainly used in XSLT, but can also be used as a much more powerful way of navigating through the DOM of any XML based language documents, such as HTML and XUL, instead of relying on the document.getElementById method, the element.childNodes properties, and other DOM Core features. The following is vague: This is especially useful within extensions, particularly regarding to overlays.


    XPath uses a path notation (as in URLs) for navigating through the hierarchical structure of an XML document. It uses a non-XML syntax so that it can be used in URIs and XML attribute values.
