Please help me find the regex for the following pattern

I want a regex pattern to find all the words of this format [xyzblab23la].

For example if the text has something like the following,

Lorem 开发者_StackOverflow社区Ipsum dolor[32a] ameit[34]

I should be able to find the [32a] and [34]. Please tell me what is the regex for this pattern?

You can use the following regex globally to find all the matches:

\[.*?\]

or

\[[^\]]*\]

Explanation:

• \[ : [ is a meta char for the start of the char class, so to match a literal [ we need to escape it.
• .*? : match everything in a non-greedy way.
• \] : to match a literal ]
• [^\]] : a char class that matches any char other than ]
• [^\]]* : zero or more char of the above type.

Try this regular expression:

\[[^[\]]+]

A short explanation:

• \[ matches a plain [
• [^[\]]+ matches one or more arbitrary characters except [ and ]
• ] matches a plain ]

/(\[[a-z0-9]+\])/i/
