Problem with http binding, REGEX syntax

[violine (Andre)]

Hello everybody,

I’ve been trying to read data from a device with http binding for a while.
My item for collecting all data looks like this:
String Test_Value1 "Performance [% s]" {http = "<[http://xxx.xxx.xxx.xxx/test.htm:60000:REGEX ((. *))]"}

I get the entire content back.
Now I only want the value 160 from the line

<div id = "pos20"> 160 </div>
read.
I just don’t get the syntax for the REGEX correctly.
There are always errors in the single quotes of “pos20”.

Can someone please help me there?
Thanks a lot!

I’m horrible at REGEX but maybe this post can help you.

[SOLVED] Regex parse on Exec binding fails

Unfortunately openHAB REGEX doesn’t behave the way standard REGEX does. For one your REGEX must match the entire message, hence Vincent’s recommendation of adding the .().. Second, you can only have one match (i.e. one ()). If you have multiple matching groups there is no way to tell the REGEX transform which one you actually want. That transform appears to have two matching groups. Finally, you must supply a matching group that defines what part you want from the string. It looks like what you…

[SOLVED] REGEX Transformation

openHAB 2.4.0-1 (Release Build) I have installed the REGEX transformation. I have tested the regular expression on regex101.com [image] This RegEx performs as expected in the LogReader binding Thing definition - i.e., a log message with that string triggers the log reader. Rich - I finally figured out how to modify the regular expression to add parentheses as you suggested. This code does what I was after. rule "Test Rule" when Item testRule received command then va…

Thank you!
The REGEX tester from regex101.com was a great help for me.

I was hoping you would find the post useful. I keep them bookmarked just for the REGEX users.

Hi there,
I was able to solve the problem.
{http = "<[http://xxx.xxx.xxx.xxx/test.htm:60000:REGEX (. *? <div id = .pos20.> (. *?) </div> (. *) )] "}
The value has a fixed number of characters.
The missing characters are also filled in with   and displayed.
This is a space as a wildcard.
e.g .:
- 0,5
  0,5
 1,5

Can I use a replace function to remove the   characters?

Thanks a lot!
