How to replace an attribute with empty string using regex?

[ashitpro]

I am parsing one xml, I want to replace an attribute with empty string.

every node has an attribute, something like this:

id="1hyx36uhpi780iq8oiu355"

I am using following regex pattern, but its not working

d = re.search('(id="([a-z0-9A-Z]+)")*',text)

In what way is it not working?

Are you parsing the XML with an XML parser such as minidom? If not, you should consider doing so.

If parsing the string directly, have you tried parsing it line by line?

This seems to work:

>>> import re
>>> patt = re.compile(r'id="[a-z0-9A-Z]+"')
>>> s = 'id="1hyx36uhpi780iq8oiu355"   xxxxx xxxxx id="46fhrt5976jkfjhrh"'
>>> s1 = patt.sub('id=""', s)
>>> s1
'id=""   xxxxx xxxxx id=""'
>>>

ashtipro,

It looks like you've got a problematic indefinite repetition operator in your statement:

d = re.search('(id="([a-z0-9A-Z]+)")*',text)
    HERE  --------------------------^
 

Which I think will cause undesired matches of zero length.

Also, I don't know what your data stream looks like, however you may need to check for single quotes (')enclosing the attribute value, as well.

Luck!
