itemquery and itemquerymap

[Stephen Lime]

Itemquery uses regex's not strcmp. So just use a value like ^191$ and that should ensure a unique match.

I'm trying to use the itemquerymap mode to return a query map depicting the
polygon I've just selected from a list of polygon numbers. This works fine
for polygon numbers that are completely unique (ie contain the maximum
amount of characters), however for thos that are not entirley unique I get
multiple results (which I don't want).

For example, if I submit polygon number 191, I get a query map showing me
polygons "191" and "1191" (there are only 1400 polygons, so 4 digits is the
maximum).

I think I need to use a regular expression to tell MapServer to match the
polygon number returned entirely, and not to view it as a string that may be
part of a larger text string.

Does anybody have any thoughts on how I might achieve this?

Thanks

Rob
