Very sorry about that , especially because it was updated more or less for you.
Now I have a serious problem, I have no way to look into it because I have no linux ..
and I am an absolute linux dummy ..
Can't you use windows until I find a solution?

Unfortunately I can only run this on linux - no Windows server available.

Here is attachment with verbose mono output, maybe will help

I did some tests and the error is there with windows also so I think your mono version is not the problem.
you will have to wait until jan responds.

Thanks, it is working now. Even with new element-names:

Quote:

< desc >{¤ 'category( / )[cleanup(style=sentence tags="("")"), max_sentences=1]' }{¤ 'country(/)' }{¤ 'productiondate' }{¤ 'rating' }{¤ 'starrating'}{\n'description'}{\n¤ Reżyseria: 'director(, )'}{\n¤ Prowadzący: 'presenter(, )'}{\n¤ Występują: 'actor(, )'}< /desc >

Can anybody help me?
Even with the latest version of wg ++ (3.1) I have an error and I can't generate the rex.
This happens on both windows and linux.

Sorry for the late reaction .. I wish I had more time for the postprocessor...

But , I located the cause of the crash. It is caused by a change in the code that isolates attributes from their element value. (I changed that code 3.0.2 beta and didn't notice that the new code fails under certain conditions). It occurs if a multi value element has no attribute for the last of the element values (so also when it has no attributes at all). This will probably happen with element actor when it has no role attribute and when specified 'actor/a' or 'actor/a+' in rex.config or mdb.config
The next beta will have this fixed but that will take some time because there are a few other open 'todo's for that.

Of course it can also be fixed by removing the /a or /a+ from 'actor' . It is very unlikely that other elements will have problems with this bug.

Hello
I just upgraded to version 3.1.1 and I can't generate rex

No matter what I do, it always gives error.

In version 3.1 I had no problems.

Would you help me?

well the error seems to be that cannot find REX folder....
Folder /root/.wg++/REX doesn't exist!

It may be that new version needs that.....will notify authors so it can be added to siteini.pack

Even though I created a folder "REX" it still gives an error ...

Is there anything I can do?

double check you created the REX folder in the correct place.
also make sure ur re.config.xml is in there.

although i have webgrab installed in a diff directory it works fine for me on linux.

Job (REX Version: 3.0.0) started at 08/09/2020 19:45:17
Starting REX Postprocess
.. done
File written to :
/raid/NAS_WebGrab/rex/rex_guide.xml

if you look at the last line you will see the rex guide.xml is written to the rex folder(all lower case).

for linux users this bug exists for both rex and mdb.
the config files most be in a folder spelled with all capital letters but the resulting guide.xml is written to one with lower case spelling.

i mentioned this to the author some time ago but it would nt hurt for matt8861 to remind him.

this is a different error,it finding ur rex config fine.
if your rex.comfig.xml
change this..
'description[max_words=100]'
to
'description'
there seems to be a issue with max_word,max_sentences.the creator knows about this.

any kind of postprocessing allowed in rex

eg [cleanup(style= or [max words

is NOT functional in linux

mono 6.8 full installed on ubuntu 20.04 server, with the ltest webgrab beta

all other functions work in rex except postprocessing between []

[cleanup(style=lower)] also causes it [cleanup(style=name)] also causes it [cleanup(style=upper)] also causes it ;)
