[Mapserver-users] regular expression help

[Stender, Amy ERDC-CRREL-NH Contractor]

hello,

i'm trying to write a regular expression in my map file. to recognize:

1. shrub native__salix exigua
2. shrub native__salix goodingii
3. shrub native__salix laevigata
4. shrub native__salix lasiopis
etc...

i found that the following regular expression works for my CLASS EXPRESSION: /shrub native__*/

BUT now i have:

1. Trees/Woodland/Forest, Native__blah
2. Trees/Woodland/Forest, Native__blah1
3. Trees/Woodland/Forest, Native__blah2
4. Trees/Woodland/Forest, Native__blah3

the forward slashes confuse my regular expression, so i tried using escape characters:
/Trees\/Woodland\/Forest, Native__*/

but this did not work. the error is: loadClass(): Unknown identifier. (Woodland/Forest).

any ideas on another escape character or a work-around?

thanks,
amy
