Jul 13, 2012 · In a regex designed to "split" a string, the regex will necessarily match the character(s) on which to split. That is exactly what you are seeing, and what I would expect. But now you are presenting a different requirement which involves capturing, and perhaps replacing, those items.

Regular Expression Extractor Syntax. When configuring the regular expressions in JMeter, use the same syntax as Perl5.

This collides with Python’s usage of the same character for the same purpose in string literals; for example, to match a literal backslash, one might have to write '\\' as the pattern string, because the regular expression must be \, and each backslash must be expressed as \ inside a regular Python string literal.
Python raw string is created by prefixing a string literal with ‘r’ or ‘R’. Python raw string treats backslash (\) as a literal character. This is useful when we want to have a string that contains backslash and don’t want it to be treated as an escape character.

Jan 21, 2019 · Ignore Case While Matching. So far, we have looked at patterns when the case of the letters mattered. How can we make our RegEx patterns to be case insensitive?

That expression takes the $1 capture from the regex (which is already missing the quotes) and translates (y///, which can also be written as tr///) it by deleting (/d) all the commas. The r flag to y is necessary in order to get the value to be the translated string, instead of the count of translations. Python provides three methods that can be used to trim whitespaces from the string object.
