What is XPath?

It stands for XML Path Language because it uses “path like” syntax to identify and navigate nodes in an XML document. With over 200 built-in functions is also a W3C recommendation.

XPath Path Expressions:

There are over 200 built-in functions provided for string values, numeric values, booleans, date and time comparison, node manipulation, sequence manipulation, and much more in XPath. In languages like JavaScript, Java, XML Schema, PHP, Python, C and C++, and others, XPath expressions can be used.
