I have this item configuration:  
`Number Solar_Leistung "Solar [%d W]" <sun> (Solar) {http="<[http://192.168.178.220/min_day.js:60000:REGEX((?<=\\|)(\\d*)(?=\\;))]"}`

I get this log:  
` 7:57:51.127 INFO runtime.busevents[:26] - Solar_Leistung state updated to m[mi++]="14.02.16 17:10:00|0;0;0;964;226;226;21" m[mi++]="14.02.16 17:05:00|0;0;0;964;256;256;22" m[mi++]="14.02.16 17:00:00|0;0;0;964;274;274;22" m[mi++]="14.02.16 16:55:00|0;0;0;964;264;264;22" m[mi++]="14.02.16 16:50:00|0;0;0;964;259;259;22"`

I’m trying to match only the first line and the number between | and ; which is currently 0. I tested my regex on [Java regex testing - RegexPlanet](http://www.regexplanet.com/advanced/java/index.html) and it looked fine to me.

Any advice would be great.

Something with one capture value, more like:

```auto
.*?\|(\d+);.*

```

… or the Java-escaped variant 😉

`REGEX` adds a `^` and `$` to the beginning/end (resp) of the string supplied, so this will only catch the first value.

EDIT: Here’s an example of it in rule form:

```auto
rule "test regex 4"
when
   Time cron "0/10 * * * * ?"
then
   var VALUE = 'm[mi++]="14.02.16 17:10:00|0;0;0;964;226;226;21"\nm[mi++]="14.02.16 17:05:00|0;0;0;964;256;256;22"\nm[mi++]="14.02.16 17:00:00|0;0;0;964;274;274;22"\nm[mi++]="14.02.16 16:55:00|0;0;0;964;264;264;22"\nm[mi++]="14.02.16 16:50:00|0;0;0;964;259;259;22"'

   logInfo('regex4', 'original=' + VALUE + ' new=' + transform('REGEX', '.*?\\|(\\d+);.*', VALUE))
end

```

and the output:

```auto

10:21:30.012 DEBUG o.o.c.t.i.s.RegExTransformationService[:42]- about to transform 'm[mi++]="14.02.16 17:10:00|0;0;0;964;226;226;21"

Thanks, it is working in my .item file now.
