This turned out to be easier than I thought, so I could do it before leaving.

- Supplementary question.
Can this be extended to find patterns defined using regular expressions ?
eg add to the above pattern file :
<group id="group-3">
<alarm equipment="MDU X[0-9]{4} Relay fail"/>
<alarm equipment="MDU X[0-9]{4} Fuse fail"/>
</group>
I can help if you don't mind using the following notation using
grouping parentheses:
<group id="group-3">
<alarm equipment="MDU X([0-9]{4}) Relay fail"/>
<alarm equipment="MDU X([0-9]{4}) Fuse fail"/>
</group>
The result would be changed to add the following :
<area name="LAR 23">
<alarm equipment="MDU X2301 Relay fail" found="group-3"
found-group="1" found-key="2301" />
<alarm equipment="MDU X2301 Fuse fail" found="group-3"
found-group="1" found-key="2301" />
Wouldn't that be found-group="2"?
I hope the example below helps.
