mohan123 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks, I am supposed to get a compressed xml string from a server by LWP.
Now i want to decompress it using the Compress::Zlib module.

For doing a simple test i tried to first compress a big string and then decompressing it using this i found on the cpan documentation page for the module. 


   use Compress::Zlib;
   my $str_to_compress='a big string';
   $compressed_str=compress($str_to_compress[,1]);
   #original syntax on cpan for the two functions
   #$dest = compress($source [, $level] ) ;
   #$dest = uncompress($source) ;
   $decompressed_str=uncompress($compressed_str);
   print $decompressed_str;

but when i try to run it it says wrong syntax.
please tell me the correct syntax or any other method to do it.

    I think you misunderstood the [, $level] part of the docs: it's intended to mean that the ", 1" part is optional. As you wrote it it simply won't compile. 

    syntax error at test.pl line 3, near "[,"
Execution of test.pl aborted due to compilation errors.

    Try this: 
       use Compress::Zlib;
   my $str_to_compress='a big string';
   $compressed_str=compress($str_to_compress,1);
   $decompressed_str=uncompress($compressed_str);
   print $decompressed_str;

    By the way, please note exact error message text next time. Paraphrasing errors will only confuse people.
