I just tried to replace the first line with nothing and the second line as full line.
But this is not working
AC40corrected.replace("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"","")
If I append the replace after the first two replaces it works. Is it not possible to replace text in variable?
The String with the replaced text gets returned. The original String remains unchanged. You would need to use:
AC40corrected = AC40corrected.replace("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"","")I’ve written it now in a very long oneliner.
But I still get this version error!
Thank for the tip with the variable. I should have seen that, but I was concentrated with escaping the double quotes 
The missing “>” has to be a different place and perhabs nothing to do with the version.
Here comes the complete error log

No I’am missing the error logs. 
But what I was trying to do? Ah I wanted to transfer some important values to an item.
This still fails

It doesn’t like this part of the header string.
That is the HTML escaped character for the ä.
XML does not include everything that HMTL does when it comes to escaped characters and such so it is likely this is not part of standard XML.
Try replace("ä", "ä").
Look for other places where there might be an HMTL escaped character and replace those as well.
You missed my answer
Print out the result of the transform and make sure you are getting something.
It looks preaty good

this is the last line to transfer the value to the item
TL300E02B01.sendCommand (AC40_TL300E02B01)
the line has the following error
The method or field TL300E02B01 is undefined
Do I have to change the dot in the number to an comma?
The error is saying that the Item TL300E02B01 doesn’t exist. Make sure you don’t have a typo in on that Item as well.
The dot is fine. You would probably have problems if you used the comma.
Make sure there is no leading or trailing spaces in the String returned from the transform.
May be I have a trailing space.
How can I strip the string? Is there a command like .strip ?
.trim

Your are right. Indeed the http binding is working.
But don’t tell me that it was easy
I never said it was easy. Dealing with raw data from websites and other devices is hard even for experienced programmers. The fact that you are dealing with a not well-formed HTML that you wanted to use XSLT on made it even more of difficult.
It would have been easier had you taken my hint and used Regex instead.
What version of Designer are you using? Is it 0.9? If so that is your problem. There is a major problem in the 0.9 version that is causing it to no recognize Items. You should use the 0.8 version.
Thats a good question. I downloaded both, but in the running Designer I can’t see on which Version I’am, but I supose I’am a lucky man and startet immediately with the newest version to have less trouble, Only with my openhabian I was a little bit to conservative. (Thats also not true, I realy was one of the first users)
On Thursday I will try to get the Modbus Binding via USB-RS485 to get to run.
What do you think about that?
Thanks a lot for your patience and help.
I don’t know much about this binding. Good luck!
Hello I have to go on with this thread.
I now have the problem, that I have Setpoints and Switches I would like to change.
So I have to change my items and rule file.
I would like to keep my
String AC40_Raw { http="<[AC40CacheRaw:60000:REGEX((.*))]" }
but instead of selecting everything I would like to do the necessary changes which in the moment are done in the rule file
when
Item AC40_Raw received update
then
// logInfo("Process AC40", "Beginn Auswertung")
val AC40corrected = AC40_Raw.state.toString.replace("<br>", "<br/>")
AC40corrected = AC40corrected.replace("<META HTTP-EQUIV=\"Refresh\" CONTENT=\"30\">", "")
AC40corrected = AC40corrected.replace("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"","")
AC40corrected = AC40corrected.replace("\"http://www.w3.org/TR/html4/loose.dtd\">", "")
AC40corrected = AC40corrected.replace("<h2>Liste der ausgewählten FG-Adressen:</h2>","")
directly.
The sendcommands in my rule file
TA300A00B91.sendCommand (transform("XSLT", "AC40_TA300A00B91.xsl", AC40corrected).trim)
TL300E01B01.sendCommand (transform("XSLT", "AC40_TL300E01B01.xsl", AC40corrected).trim)
TL300E02B01.sendCommand (transform("XSLT", "AC40_TL300E02B01.xsl", AC40corrected).trim)
should be placed in the items file directly
Number TA300A00B91{ http="<[AC40_Raw:10000:XSLT(AC40_TA300A00B91.xsl)]" }
And later on I would like to define the http post
Number TA300A00B91{ http="<[AC40_Raw:10000:XSLT(AC40_TA300A00B91.xsl)] >[CHANGED:POST:http:////192.168.1.200/cgi-fga/fga/fgacmd/TA300A00B91?pw=0123456789&nv=18]" }
The final “18” should become replaced by the changed value.
What do I have to change to get in running?
Is it possible to get a multiple selection with a regex?
A regex can select multiple things but I don’t think OH is able to take advantage of it.
See the HTTP binding for how to configure the binding to send requesters. One thing I notice is for outgoing you should use > instead of <
