Or do you mean extract lines matching (the query derived from) $word from all the lines in $sent?

Code:
# parse query and make a (slightly generalized) regex out of it
my $regex = $word;
$regex =~ s/\s+/[- \\s]/g;

# print all lines matching $regex
while ($sent =~ m/(.*$regex.*)/go) { print "$1\n"; }

If you have multiple patterns you either put them all on a list and check one by one or create an expression that allows spaces or '-' between words (but that could be faulty and you would lose track of things)


Hi


I have to match $sentences with $word and $word can have "RNA binding protein" or RNA-binding protein.

How to match $sentences?

[CODE]

if($sentences=~/$word/) //$word can be "RNA binding protein" or RNA-binding protein.
{

}
I want to check $word for these conditions and match?

how should i do that?

Hi,

I want to match $sentences with $word like this:

Code:
if($sentences=~/$word/)
{

}

Here $word refers to "RNA binding protein" OR "RNA-binding protein".

How can i write expression such that $sentences matches with $word(it should match "RNA binding protein" and "RNA-binding protein")?

$word should work for both conditions and $sentences should match $word!!

How can i do that?

As far as I can see redoubtable's post already answers your question. Does it not work for you?

I'm not sure I understand what the original poster wants but I think this should answer any possible question he/she might have.

Code:
$sentences = "

Protein modeling studies reveal that the RG-rich region is part of a three to four strand antiparallel beta-sheet, which in other RNA binding protein functions as a platform
for nucleic acid interactions.

Heterogeneous nuclear ribonucleoparticle (hnRNP) proteins form a family of RNA binding proteins (RBPs) that coat nascent pre-mRNAs.

Finally, we have found that Pumilio2, a member of the PUF family of RNA-binding proteins, is highly concentrated at the vertebrate neuromuscular junction.

PUF proteins comprise a highly conserved family of sequence-specific RNA-binding protein that regulate target mRNAs.";

$word = '(.*?RNA[-\s]binding protein.*?)(?:\n|$)';

while ($sentences =~ /$word/g)
{
        print "$1\n";
}

This will print all matches of the specified pattern $word in $sentences.

Hi,

I have highlight these words in sentences (words include "RNA binding proteins" and "RNA binding protein" and "RNA-binding protein" and "RNA-binding proteins").

How to highlight all these words in sentences?

I tried using like this but its highlighting only 2 sentences.

Code:
$sentences=~s/(\b$regex\b)/<span style="background-color:#E1FF77">$1<\/span>/img;

How to highlight all words?

With regards
Vanitha
