I am in the process of re.sub the tag <item type="dict"> </item> with empty string from a xml output line.
If "re.I" is used, I am not able to remove the complete tag.
========================================================================
>>> a
'ype="str">false</latency_statistics_enabled><name type="str">Default</name><aggregates type="list"><item type="dict"><aggregate type="list"><item type="dict"><type type="str">MulticastClient</item><is'
>>> b = re.sub('\<\/?item(\s+type="dict")?\>', '', a, re.I)
>>> b
'ype="str">false</latency_statistics_enabled><name type="str">Default</name><aggregates type="list"><aggregate type="list"><type type="str">MulticastClient</item><is'
>>> b = re.sub('\<\/?item(\s+type="dict")?\>', '', a)
>>> b
'ype="str">false</latency_statistics_enabled><name type="str">Default</name><aggregates type="list"><aggregate type="list"><type type="str">MulticastClient<is'

The 4th argument of re.sub is the count, not the flags. Not a bug. |

Thanks for the inputs, It would be of great help, if someone could help me in explaining the below output :
========================================================================
>>> a
'ype="str">false</latency_statistics_enabled><name type="str">Default</name><aggregates type="list"><item type="dict"><aggregate type="list"><root><type type="str">MulticastClient</root><is'
>>> b = re.sub('\</?root\>', '', a, re.I)
>>> b
'ype="str">false</latency_statistics_enabled><name type="str">Default</name><aggregates type="list"><item type="dict"><aggregate type="list"><type type="str">MulticastClient<is'
========================================================================

The pattern '\</?root\>', which is the same as '</?root>', matches the string '<root>', and that is replaced with ''. |

:-) Thanks a lot Matthew for the inputs. If we compare the first example (<item>) and the <root> example, I am using re.I as the third element. But for the <root> example, still I am not to get the substitution happening correctly. Could you pls, let me know the reason of change in behaviour. |

The 3rd argument is the count (the maximum number of replacements, although 0 means no limit, not no replacements). You're passing in the flag re.I instead. re.I happens to have the numeric value 2, so you're telling it to do no more than 2 replacements. |
