xml-extractors: Wrapper over xml to extract data from parsed xml

[ bsd3, library, xml ] [ Propose Tags ]

This is a library to simplify extraction of data from parsed xml.

See the Text.XML.Light.Extractors module for an example.

Motivation

The xml package provides functions to parse and get information from xml data. It will parse an xml string into a generic tree representation. Extracting information from such a tree while keeping track of location to handle errors is tricky. This library helps with that.

If there is an error during extraction (expected information is absent or wrong), it will return an error value with position information.

Some limitations

  • Only handles unqualified names. (This is by design to simplify usage.)

  • No column number and sometimes no line number reference in error values.

xml-extractors

Simple wrapper over xml to extract data from parsed xml.

When parsing xml strings with XML.Light you get a list of Content. Then you can use functions from Text.XML.Light.Proc to extract data from that. It is however kind of tricky to deal with the potential errors -- we have a parsing problem again.

Instead of Text.XML.Light.Proc one can use this library. It simplifies the process of extracting data from Content while dealing with errors.
