Wicked-good-xpath

[Joke Grinman]

XPath stands for XML Path Language. It uses a non-XML syntax to provide a flexible way of addressing (pointing to) different parts of an XML document. It can also be used to test addressed nodes within a document to determine whether they match a pattern or not.

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-like language document using XPathExpression, such as HTML and SVG, instead of relying on the Document.getElementById() or Document.querySelectorAll() methods, the Node.childNodes properties, and other DOM Core features.

Note: Support for XPath varies widely; it's supported reasonably well in Firefox (although there are no plans to improve support further), while other browsers implement it to a lesser extent, if at all. If you need a polyfill, you may consider js-xpath or wicked-good-xpath.
