regex - Python regular expression replace string -

-

i have following code:

 a="32<2>fdssa</2>ffdsa32"  re.sub(r'<(\d+)>|</(\d+)>',"item",a)

the result get:

32itemfdssaitemffdsa32

i want result:

32<item>fdssa</item>ffdsa32

you need capture </ part. 

re.sub(r'(</?)\d+>',r"\1item>",a)

since made / optional, (</?) capture < or </

example:

>>> a="32<2>fdssa</2>ffdsa32" >>> re.sub(r'(</?)\d+>',r"\1item>",a) '32<item>fdssa</item>ffdsa32'

(i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
