Searching

http://docs.python.org/library/re.html#matching-vs-searching

"... match checks for a match only at the beginning of the string ..."

>>> import re
>>> p = re.compile('(\[&&NHX:)')
>>> p.match("[&&NHX:C=0.195.0]")
<_sre.SRE_Match object at 0x01C2FEA0>
>>> p.match("-bin-ulockmgr_server:0.99[&&NHX:")
>>> p.search("-bin-ulockmgr_server:0.99[&&NHX:")
<_sre.SRE_Match object at 0x01C2FF60>
>>> p.findall("-bin-ulockmgr_server:0.99[&&NHX:")
['[&&NHX:']
>>>
