nkit4py 2.1.1

Fast XML to Python data (and vise versa) converter and filter. Written in C++ using Expat SAX parser.

Introduction

nkit4py - is a nkit C++ library port to Python (see https://github.com/eye3/nkit.git). There is the same port to Node.js - nkit4nodejs (see https://github.com/eye3/nkit4nodejs.git)

With nkit4py module you can convert XML string to Python data and vise versa.

With XML-to-Python-data possibilities you can:

• Create Python data structures, which are different from the structure of XML source.

• Create multiple Python structures from one XML source.

• Explicitly identify those elements and attributes in XML source that you want to use for building Python data structures. Thus, it’s possible to filter out unnecessary XML-data.

• Explicitly define Python type of scalar (primitive) data, fetched from XML source. Integers, numbers, strings, datetimes and booleans are supported.

• Control progress of chunked download and parsing of big XML string

• With extra options you can tune some aspects of conversion:

  • trim text data

  • explicitly define white space characters for trim option

  • choose unicode or string type for text data

Conversion is carried out using SAX parser Expat, so it’s fast and uses less memory when parsing huge XML files.

Module supports not only native Expat XML encodings, but also many others (see /deps/nkit/src/encoding/langs.inc)

With Python-data-to-XML possibilities you can:

• Define root element name of result xml string

• Define item element name for lists

• Define encoding of result xml string

• Pretty print with custom indentation and newline characters

• Define special object key name for attributes

• Define special object key name for text

• Define which element of result xml string must contain CDATA section

• Define precision for float numbers

• Define format for Date objects
