Linebreaking in html

Posted by TedH (TedH), 15 May 2006
Hi guys,

I think this is CRLF problem but not sure how to handle it.
1)
A file is written to in Perl and looks like this:
pagetwo
pagethree

2)
The file is read and imported to an HTML file using SSI
Code:
$alist="$menufldr/$menulist";
open (MNU,$alist);
 @lines=<MNU>;
print "<a href='$urlsite/index.html'>Home</a> ";
foreach $otherfile (@lines) {
print "<a href='$urlsite/$otherfile.html'>$otherfile</a> ";
}


3)
It should be this:
Code:
<a href='pagetwo.html'>pagetwo</a> <a href='pagethree.html'>pagethree</a>


but on view source reads like this

Code:
<a href=pagetwo
.html>pagetwo
</a> <a href=pagethree
.html onFocus=if(this.blur)this.blur()>pagethree
</a>


Result is that the links do not work. I can foresee problems occuring between systems viewing the webpage (Windows, Linux, MAC) all of which have different ways of reading linebreaks.

I do not have any \n's present and can only conclude this is a result of Unix linebreaks (when file is written) and Windows (or Mac) interpretation in their respective browsers.

Is there a simple way to over come this?

Hope you can shed some light,
cheers - Ted

Yes, replace
@lines=<MNU>;
with
chomp(@lines=<MNU>);

As you read in the file, you're reading a new line sequence too. The chomp function will strip trailing new lines off the end of every element of a list.

Hi Graham, I feel really embarrassed. I had thought of that and dismissed the idea with a, "Naw, it'll be a lot more complicated than that." - so didn't try it  

I've been messing about with this CMS script and everything I've done has ended up with obscurities and strange (to me) solutions and figured this was just another one.

Thanks - Ted
