joining lines conditionally 2

[clemhoff]

Hi All,

I'm quite new to awk...
I did search on this forum but did not find a solution to my problem..

The problem i am having is how to write this in awk (or sed ):

- If a line does not end with a parenthese '(', join every following line till one begining with a ')'-

---------- Input
...
<td width="111">
En cours d'acheminement.</td>
<td width="100">
Bordeaux
&nbsp;(
33
100
)</td>
</tr>
<tr class="tabtxt">
<td width="50">
...etc

---------- Desired output
...
<td width="111">
En cours d'acheminement.</td>
<td width="100">
Bordeaux
&nbsp;(33100)</td>
</tr>
<tr class="tabtxt">
<td width="50">
...etc


Any help would be greatful.
Regards

Hi

In principle does the same as the following :

awk '/\($/,/^\)/{if(!/^)/){printf$0;next}}1' /input/file

Tested with [tt]gawk[/tt].

Excuse me for this late answer, I exceptionally granted myself long holidays

So, many thanks to Vlad and Feherke for their answers.
