and this is the corresponding part of XSL file
<CODE>
<xsl:template match="MODULE_NAME">
<form name="form1" method="POST" action="logic_file.cgi">
<tr><td><input value="{$sidx}" type="hidden" name="sidx"></input>
</td></tr>
</form>
</xsl:template>
</CODE>
on form submit on this XSL file under some flag condition,here's my logic file
<CODE>
logic code in perl
&redirect(abc.cgi?idx=$in{'idx'}&done=1); //done=1 indicating logic
file executed
</CODE>
uptil here "idx" contains only value with no ^(_at_)(_dot_)
in abc.cgi when I hit "Create",it goes to part of its code
<CODE>
if($in{'create'}) {
chomp($in{'idx'});
print $in{'idx'};
}
</CODE>
Here I am getting value appended with ^(_at_)(_dot_)

Sorry all,the code is in perl.
"abc.cgi" has $in{'idx'}.
concerned part of code
<CODE>
print "<form action=abc.cgi method=post name=abc>\n";
print "<input type=hidden name=idx value='$in{'idx'}'>\n";
print "</form>
</CODE>
on some JavaScript event,form.submit calls the same file,this part of code
<CODE>
my $parser = XML::LibXML->new();
my $xslt = XML::LibXSLT->new();
my $source = $parser->parse_file($xmlfile);

}else{
my $results = $stylesheet->transform($source,idx => "'$in{'idx'}'");
print $stylesheet->output_string($results);
}

I don't know the answer, and I suspect no-one else does either. You

given enough information. It's not even clear what programming language

Subject: [xsl] variable ending with ^@
Code flow
abc.cgi->abc.cgi on form .submit->abc.xsl on form submit->xyz.cgi
redirect->abc.cgi
"abc.xsl" passes value to next form like "<input value="{$idx}"
type="hidden" name="idx"></input>" as suggested here.
I am getting value of $in{'idx'} in final abc.cgi in above
cycle.But getting its value as "idx=14^@".
what is this "^@".I tried with chomp,chop.It still remains.
The string "^@" is a common way to make visible the control
character NUL.
If I had to guess, I'd guess that some program in your tool
chain is miscalculating a string length somewhere, or inserting
a UTF16 character from page 00 of Unicode, in a place where the
consumer of the data is expecting UTF8 or some eight-bit
character set. (The 00 octet will look to an eight-bit
application like a NUL character.)
I hope this helps. (But Michael Kay is quite right: it will
help you get better answers if you provide better information
about the problem.)
