The XML Path Language (XPath) is an expression language used by XSLT to access or refer to parts of an XML document. It is part of the XSL recommendations maintained by the W3C. XPath provides the syntax for performing basic queries upon your XML document data. It works by utilizing the ability to work with XML documents as hierarchically structured data sets.
In the following XML document, some examples of XPath references are:
- authors/author/name
- authors/*/name
- authors/author[nationality]/name
- authors/author[nationality='Russian']/name
- authors/author[@period="classical"]
In the XAI tool, XPath is used to construct outgoing messages.
