I want to extract a character from a string.
For a C/C++ programmer like me, this would seem to be the most logical and reasonable way--but it doesn't work:
$s = "abcdefg";
$c = $s;
This way is documented and it works, but it seems clumsy.
Is there any simpler way to grab one character out... (7 Replies)

xml::libxml::xpathexpression
XML::LibXML::XPathExpression(3) User Contributed Perl Documentation XML::LibXML::XPathExpression(3)NAME
XML::LibXML::XPathExpression - XML::LibXML::XPathExpression - interface to libxml2 pre-compiled XPath expressions
SYNOPSIS
use XML::LibXML;
my $compiled_xpath = XML::LibXML::XPathExpression->new('//foo[@bar="baz"][position()<4]');
# interface from XML::LibXML::Node
my $result = $node->find($compiled_xpath);
my @nodes = $node->findnodes($compiled_xpath);
my $value = $node->findvalue($compiled_xpath);
# interface from XML::LibXML::XPathContext
my $result = $xpc->find($compiled_xpath,$node);
my @nodes = $xpc->findnodes($compiled_xpath,$node);
my $value = $xpc->findvalue($compiled_xpath,$node);
$compiled = XML::LibXML::XPathExpression->new( xpath_string );
DESCRIPTION
This is a perl interface to libxml2's pre-compiled XPath expressions. Pre-compiling an XPath expression can give in some performance
benefit if the same XPath query is evaluated many times. "XML::LibXML::XPathExpression" objects can be passed to all "find..." functions
"XML::LibXML" that expect an XPath expression.
new()
$compiled = XML::LibXML::XPathExpression->new( xpath_string );
The constructor takes an XPath 1.0 expression as a string and returns an object representing the pre-compiled expressions (the actual
data structure is internal to libxml2).
