Indeed. One should note that Perl 5 has very good quoting support with its
here-documents, interpolation, variable delimiters, and also - templating
systems such as Template Toolkit. There's a thread about it on Sayeret Lambda (=
an Israeli forum of programming languages’ enthusiasts):

* https://groups.google.com/forum/#!topic/sayeret-lambda/oTdS8d0hqoE

It sparked an active discussion there.

When doing Perl, one should make a wise use of all that.

regardless of the html error you must do a better job with your strings. 
don't use single quotes when you have single quotes in the string. use a 
here document (someone posted that for you) or an alternate delimiter 
(another post showed that). that way you don't need to escape your 
internal quote chars and you can see the text better and find any 
missing angles and such.


also you can print all those in one print call. just pass the variables 
in a list to print. no need to print one at a time.

Hello again,

Apologies for the delay. I shut my laptop in frustration for the night
yesterday.

Here is a chunk of the code:

my $html2 = '/Results.tar.gz">
Download
Files
Click the button below to View your
alignment in JBrowse Viewer
http://bioinf6.bioc.le.ac.uk/~srpgrp3/UserFiles
';


my $html4 =
'/data&tracks=DNA,transcript_with_no_features,Genes&highlight=\')
  
';

print $html1;
print $directory;
print $html3;
print $directory;
print $html2;
print $directory;
print $html4;

Another person in my group had a look at it today and let me know that I
hadn't closed the button THING with a ">". Apparently with that it's able
to handle the single quotation marks.

What a fool!

Thanks,
James.

it would be most helpful if you posted your relevant perl code. if you 
say it messes up printing html i sense you are not creating your html 
strings in the best way.

Perl CGI-html quotation marks

[James Kerwin]

Hello all,

I'm currently using Perl CGI to generate a "Results" webpage. This results
webpage specifies unique directories generated within the script and print
these in between the blocks of html so various download and display buttons
work.

My problem is that I'm using a button to open a file in a new tab and the
new tab URL uses single quotes and won't work using double or none. This
then messes up the printing of the html in the Perl script.

Can anybody help me? (Example provided below).

 

If this isn't clear or it's a total sin to post html in an email to the
list then I apologise.

Any help is greatly appreciated!

Thanks,
James.
