A modern refactoring of the venerable xmltramp application
Project description
xmltramp2
====
[xmltramp](http://www.aaronsw.com/2002/xmltramp/) was originally created by Aaron Swartz
for simple-yet-powerful parsing of RSS and other xml files.
It a simple, fast and lightweight alternative to parsers such as BeautifulSoup or ElementTree. It won't do all they do, but what it does do it does simply and easily.
It has been substantially rewritten for subsequent python versions,
including python3 compatibility.
Usage is unchanged from older versions of xmltramp:
## Usage
Everyone's got their data in XML these days. You need to read it. You've looked at the other XML APIs and they all contain miles of crud that's only necessary when parsing the most arcane documents. Wouldn't it be nice to have an easy-to-use API for the normal XML documents you deal with? That's xmltramp:
```
>>> sample_xml = """<doc version="2.7182818284590451"
xmlns="http://example.org/bar"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:bbc="http://example.org/bbc">
<author><name>John Polk</name> and <name>John Palfrey</name></author>
<dc:creator>John Polk</dc:creator>
<dc:creator>John Palfrey</dc:creator>
<bbc:show bbc:station="4">Buffy</bbc:show>
</doc>"""
>>> import xmltramp
>>> doc = xmltramp.Namespace("http://example.org/bar")
>>> bbc = xmltramp.Namespace("http://example.org/bbc")
>>> dc = xmltramp.Namespace("http://purl.org/dc/elements/1.1/")
>>> d = xmltramp.parse(sample_xml)
>>> d
<doc version="2.7182818284590451">...</doc>
>>> d('version')
'2.7182818284590451'
>>> d(version='2.0')
>>> d('version')
'2.0'
>>> d._dir
[<author>...</author>, <dc:creator>...</dc:creator>, <dc:creator>...</dc:creator>, <bbc:show bbc:station="4">...</bbc:show>]
>>> d._name
(u'http://example.org/bar', u'doc')
>>> d[0] # First child.
<author>...</author>
>>> d.author # First author.
<author>...</author>
>>> str(d.author)
'John Polk and John Palfrey'
>>> d[dc.creator] # First dc:creator.
<dc:creator>...</dc:creator>
>>> d[dc.creator:] # All creators.
[<dc:creator>...</dc:creator>, <dc:creator>...</dc:creator>]
>>> d[dc.creator] = "Me!!!"
>>> str(d[dc.creator])
'Me!!!'
>>> d[bbc.show](bbc.station)
'4'
>>> d[bbc.show](bbc.station, '5')
>>> d[bbc.show](bbc.station)
'5'
