## ◆ eval()

XXPathObject eval | ( | [in] com::sun::star::xml::dom::XNode | contextNode,
|  | [in] string | expr
| ) |  |
raises | ( | com::sun::star::xml::xpath::XPathException
| ) |  |

Evaluate XPath Expression.

Parameters

  contextNode | the context node (expression is relative to this node)
  expr | the XPath expression

Exceptions

  XPathException | if the expression is malformed, or evaluation fails

Returns
  an object representing the result of the XPath evaluation
