Question Extracting Data between Tags with square Brackets
Hello @all,

first, sorry for my bad english language.
I try to extract with bash an text inside of a html page witch is finding between two tags. There is only one [ARRAY] Tag in this file. Here is an example:
Code:
[ARRAY]Wert | 53,6| 22,3| 35,5| 49,8| 40,2| 43,8| 48,0| 53,9| 35,6 | 40,2|  9,6|   59|   80|AUS|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x |Schaltzust�nde|EIN|EIN|AUS|EIN|AUS|EIN|AUS |AUS|EIN|EIN|EIN|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x |x |x |x |x |x |
Anlage2 Wert |AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS |AUS|AUS|AUS|AUS|AUS|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x|Schaltzust�nde|AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS |AUS|AUS|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x |x |x |x |x |x [/ARRAY]

I have succeeded it with the following code on the commanline:
Code:
hennerich@test-vm:/home/hennerich# cat website.htm | awk 'NR==2{print $1}' RS=[ FS=[

Only in my bash script, i have tryed the following:
Code:
#!/bin/bash

# wget Download File
URL="http://mywebspace/website.htm"

# Variable mit wget füllen
HTML=$(wget -qO- $URL)

# ARRAY Tags entfernen
# STRING="$(sed -e "o,/\[ARRAY\]/d" -e "0,/\[\/ARRAY\]/d" -i < $HTML)" -> does not work

# ARRAY Tags entfernen #2
# STRING=$(echo "$HTML" | awk 'NR==2{print $1}' RS=] FS=[) -> does not work to

In the next step i will delete all spaces and html code like $nbsp; in the STRING an finaly i need to separate alle Data between the pipes in the cleaned STRING:
Code:
[ARRAY]Wert|53,6|22,3|35,5|49,8|40,2|43,8|48,0|53,9|35,6|40,2|9,6|59|80|AUS|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x |Schaltzust�nde|EIN|EIN|AUS|EIN|AUS|EIN|AUS |AUS|EIN|EIN|EIN|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x |x |x |x |x |x | Anlage2 Wert |AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS |AUS|AUS|AUS|AUS|AUS|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x|Schaltzust�nde|AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS|AUS |AUS|AUS|AUS|AUS|x |x |x |x |x |x |x |x |x |x |x |x |x |x |x |x [/ARRAY]

and declare it as new variables. The result will show as ...:
Code:
$wert1 #content is 53,6
$wert2 #content is 22,3
$wert3 ...
$wertn ...

Have you any idea how i can realize this project.
Thank you very much for your help and ideas!

Greetings
hennerich
