Select parts of a document by a string representing a XPath expression.

The main filter for selecting parts of a document via XPath. The string argument must be a XPath expression with an absolute location path, the argument tree must be a complete document tree. Result is a possibly empty list of XmlTrees forming the set of selected XPath values. XPath values other than XmlTrees (numbers, attributes, tagnames, ...) are converted to text nodes.

Select parts of an XML tree by a string representing an XPath expression.

The main filter for selecting parts of an arbitrary XML tree via XPath. The string argument must be a XPath expression with an absolute location path, There are no restrictions on the arument tree.

No canonicalization is performed before evaluating the query

Result is a possibly empty list of XmlTrees forming the set of selected XPath values. XPath values other than XmlTrees (numbers, attributes, tagnames, ...) are convertet to text nodes.

compute the node set of an XPath query

Select parts of a document by a namespace aware XPath expression.

Works like getXPath but the prefix:localpart names in the XPath expression are interpreted with respect to the given namespace environment

Same as getXPathSubTrees but with namespace aware XPath expression

compute the node set of a namespace aware XPath query

The main evaluation entry point. Each XPath-Expr is mapped to an evaluation function. The Env-parameter contains the set of global variables for the evaluator, the Context-parameter the root of the tree in which the expression is evaluated.

parse an XPath expr string and return an expr tree or an error message. Namespaces are not taken into account.

parse an XPath expr string with a namespace environment for qualified names in the XPath expr and return an expr tree or an error message

Select parts of a document by an already parsed XPath expression

Select parts of an XML tree by an XPath expression.

compute the node set of an XPath query for an already parsed XPath expr
