Last changes

0.0.1: * added function: string-join

Description

Set of Xpath2 functions which you can register in lxml. User register all or chosen functions and use them in own xpaths. Xpaths are accessible under default namespace: kjw.pt/xpath2-functions or empty namespace if needed.

Usage

Example:

from lxml import etree
import xpath2_functions

# registering all available functions in default namespace
xpath2_functions.register_functions(etree)

# registering chosen functions in the empty namespace
xpath2_functions.register_functions(etree, ns=None, functions=['string-join'])

Functions

• string-join(arg1 as xs:string, arg2 as xs:string) - returns a arg1 created by concatenating the members of the

  $arg1 sequence using $arg2 as a separator. If the value of $arg2 is the zero-length string, then the members of $arg1 are concatenated without a separator.
