Bottom-up transformation of XML into python generators, XML, JSON or text.

Project description

This library does a bottom-up transformation of XML documents, extracting the parts that are relevant for the task at hand, and either returning it as a python generator, or serializing it to disk as XML (again!), JSON or text.

One design goal is to be able to process gigabyte-sized documents with constant memory footprint.

Inspired by the Haskell libraries Scrap Your Boilerplate, uniplate and geniplate.

Example, get the texts from all <p> tags in a document:

from xmldestroyer import xd
import sys

def p(text, _attrs, _children, _parents):
    return text

infile, outfile = sys.args

xd(infile, outfile, p=p)

This outputs a text file with the text from all <p> tags, one per line.

Works with python 2.7, 3.3, 3.4 and 3.5.
