From the link given here :
http://search.cpan.org/~kmacleod/lib...oc/PerlSAX.pod
Perl sax seems to split the characters call for a single entity.
Though this is wierd.(not sure if there is a genuine reason) it is
fine.. as all belong to same entity, we can simply append all the
characters calls.
However ,sadly it just calls the characters api with an unwanted
space.
Eg: i've tag < tag1>mynameisrs</tag>
it calls characters("myname") characters(" ") characters("isrs") ,
It is not atall predictible why it is doing this way. coz the problem
is when i append it becomes "myname isrs".
Any help is appreciated.
Thanks

The URL you provide says this:

"The Parser will call this method to report each chunk of character
data. SAX parsers may return all contiguous character data in a single
chunk, or they may split it into several chunks;"

That isn't well formed XML and so cant be parsed.
1. you have a space in front of the firts tag name.
2. you open tag1 but close tag.

In my experience it is always sufficiently predictable. Probably your
mynameisrs data is split over several lines and you've not written your
handler to take this into account.


$ cat sax.pl
#!/usr/local/bin/perl
use strict;
use warnings;
use XML:arser:erlSAX;

my $xml="<tag>mynameisrs</tag>";

my $handler = MyHandler->new();
my $parser = XML:arser:erlSAX->new(Handler=>$handler);

$parser->parse($xml);


package MyHandler;
use strict;
use warnings;
use Data:umper;

sub new {
my $type = shift;
return bless {}, $type;
}

my $current_element = '';

sub start_element {
my ($self, $element) = @_;
$current_element = $element->{Name};
print "Start: <$current_element>\n";
}

sub end_element {
my ($self, $element) = @_;
print "End: \n";
}

sub characters {
my ($self, $characters) = @_;
my $text = $characters->{Data};
print "Characters: '$text'\n";
}

1;


$ perl sax.pl
Start: <tag>
Characters: 'mynameisrs'
End:

sorry for the wrong input provided earlier.. it was my hurry to type
quickly
i intended to type <tag>mynameisrs</tag>

Yes, the perlsax occasionally splits the chars to multiple calls. ur
snip doesnt seems to handle it!.
My actual query is in addition to the calls made to the charchters api
with the split chunks, it randomly calls the characters API with a
unwanted space..
Thanks again for ur earlier reply.

My program wasn't intended to handle it, it was intended to show that no
unexpected space characters are inserted.

It never does for me!

Create and post a short working program that shows it!

You should not attempt to type code or data at all.

You should instead copy/paste it so that you do not insert
errors that are not in your real code or data.
