et_xmfile
|
|
=========
|
|
|
|
XML can use lots of memory, and et_xmlfile is a low memory library for creating large XML files
|
|
And, although the standard library already includes an incremental parser, `iterparse` it has no equivalent when writing XML. Once an element has been added to the tree, it is written to
|
|
the file or stream and the memory is then cleared.
|
|
|
|
This module is based upon the `xmlfile module from lxml <http://lxml.de/api.html#incremental-xml-generation>`_ with the aim of allowing code to be developed that will work with both libraries.
|
|
It was developed initially for the openpyxl project, but is now a standalone module.
|
|
|
|
The code was written by Elias Rabel as part of the `Python Düsseldorf <http://pyddf.de>`_ openpyxl sprint in September 2014.
|
|
|
|
Proper support for incremental writing was provided by Daniel Hillier in 2024
|
|
|
|
Note on performance
|
|
-------------------
|
|
|
|
The code was not developed with performance in mind, but turned out to be faster than the existing SAX-based implementation but is generally slower than lxml's xmlfile.
|
|
There is one area where an optimisation for lxml may negatively affect the performance of et_xmfile and that is when using the `.element()` method on the xmlfile context manager. It is, therefore, recommended simply to create Elements write these directly, as in the sample code.
