XPath

Browse implementation

Following functions help you execute XPath request on XML document.

Important

Those functions have two specific behaviors :

• Return the first value in the XPath query result set type-cast to the return type of this XPathExpression.
• Try hard to return strings, i.e. try to unwrap, when possible, the dom element, attribute or element CDATA.

Therefore, the object returned type could be :

• String
• Element
• Generic type of the xpath expression
