I must find "Remove colour consent form" or "do not send colour consent form to author"; or "remove CCF form"
And "Special Issue" and "remove CCF form" sentences in *.xml file.

how to write it correctly with Perl ?!

[sterno73]

$line =~ /(remove|(do not send)) <br />c(olour\s)?c(onsent\s)?f(orm\s)?<br />
(form\s)?(to\sauthor)?/i;
<br />
The above will match everything listed except for "Special Issue", hopefully that will be easy enough. You can use this if you want to just treat the file like a text file. If you are using one of the xml modules to parse the file, there might be easier ways to find the lines you've listed. Try searching on cpan.org for xml. The question is pretty open as to the approach being taken, and if you've been around Perl much, you know TIMTOWTDI.
