Searching a string and extract all occurancies of a substring

[Anthra Norell]

Nico, perhaps this would be suitable:

>>> s = '''Example text:
This is a test. <link url="/www/folder" target="_self" title=""> A test. 
<source id="box"><parameter key="path">/www/mydoc1</parameter></source> 
And I need to extraxt /www/mydoc1 and /www/mydoc2 from this text.
<source id="box"><parameter key="path">/foo/bar/doc</parameter></source> ...'''

>>> import SE
>>> Thing_Filter = SE.SE ('<EAT> "~<source id="box"><parameter key="path">(.|\n)*?</parameter></source>~==" | "~<.*?>~= " ')
>>> print Thing_Filter (s).split ()
['/www/mydoc1', '/foo/bar/doc']


If you expect more than one of these sections and need a list of records, it would take no more than an additional split.

You'd find SE here: http://cheeseshop.python.org/pypi/SE/2.2%20beta
