I'm brand new to regular expressions. I've read http://www.gammon.com.au/mushclient/regexp.htm and I'm having trouble visualizing what I need. How can I ignore the white space and simplify this to not worry about spacing?


    <trigger
        enabled="y"
        match="^\| Type       \: (.*?)                  Level  \:     (.*?)           \|$"
        regexp="y"
        script="capture_type_level"
    >
    </trigger>

I am extracting the data from the "ID pearl" command on aardwolf. Here is an example.


+-----------------------------------------------------------------+
| Keywords   : 41neck openstock touchstone pearl Asura            |
| Name       : (>Asura's Azurite Pearl<)                          |

Use \s+ to match one or more spaces.


<triggers>
  <trigger
   enabled="y"
   match="^\| Type\s+\: (\w+)\s+Level\s+\:\s+(\d+)\s+\|$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>

Note ("Type = %1")
Note ("Level = %2")

</send>
  </trigger>
</triggers>

For advice on how to copy the above, and paste it into MUSHclient, please see Pasting XML.

Also if you know you are expecting digits you can use \d+ (one ore more digits). The above worked on your test data.
