What is wrong with registerNs()?

my $dom = $parser->parse_file("book.xml");
my $root = $dom->documentElement();
my $xpc = XML::LibXML::XPathContext->new($root);

$xpc->registerNs(xlink => "http://www.w3.org/1999/xlink") or die "Coul
+dn't register Namespace - $!";

The xml file is :

<?xml version="1.0" encoding="UTF-8"?>

<book:bookResource xmlns:xlink="http://www.w3.org/1999/xlink">

<book:chapter id="bk111111ch1" type="CHAPTER">

In reply to Not able to register namespace in XML::LibXML on Linux. by ravi06

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
