Re: [Handle-info] Template Handles

[Robert R Tupelo-Schneck <schneck@cnri.reston.va.us>]

The example in the Handle Technical Manual should show how to use regular expression matching to pull out parts of the handle which can then be plugged into the handle values.

For instance, this template should turn 12345/abc@repl1-repl2 into a handle with the URL value you want:

        <template delimiter="@">
              <if value="extension" test="matches" expression="(.*)-(.*)" parameter="x">
                    <value type="URL" data= "http://www.library.wisc.edu/collections/${x[1]}/item?get=${x[2]}"; />
              </if>
        </template>

Let me know if that helps!
