Looking for a regex solution:
\[[^\[\]]*\]\s*[<>|<=|>=|=|>|<]\s*'?"?\w*'?"?
This regex is designed to parse equations like:
[household_roster_relationships_topersona_nameadditionalpersono] = "1"
It works well with operators such as
'=','>','<'.
However, when dealing with operators like
'<=','>=','<>'.
The parsing stops at the first character of
'<=','>=','<>'.
A demo has been created on regex101
How can this regex be corrected to handle these situations?
To make a simple alteration, modify your character classification:
\[[^\[\]]*\]\s*(><|>=|==|=|>|<)\s*'?"?\w*'?"?
^ ^
In order to improve your regular expression, you should swap out the character class with a grouping construct.
Here is the revised code:
\[[^[\]]*]\s*(?:<>|[<>]=|[=><])\s*['"]?\w*['"]?
^^^ ^
Visit the regex demo. The
(?:<>|[<>]=|[=><])<>, <=, >=, =, > or <.
Note that I streamlined some alternative branches in order to condense the pattern. Additionally, it seems like you only want to match either ' or " at the end, so simply including ['"]? (representing 1 or 0 instances of ' or ") should suffice.
Furthermore, there is no need to escape a [ within a character class ([[] denotes a single [), and outside of a character class, there's no requirement to escape ] since it represents a literal ] symbol.
To select a character class with multiple words, make sure to use () instead of []...check out the revised regex pattern here
