Xacobeo::Document - An XML document and its related information.
SYNOPSIS
use Xacobeo::Document;
my $document = Xacobeo::Document->new_from_file('file.xml', 'xml');
my $namespaces = $document->get_namespaces(); # Hashref
while (my ($uri, $prefix) = each %{ $namespaces }) {
printf "%-5s: %s
", $prefix, $uri;
}
my $nodes = $document->find('/x:html//x:a[@href]');
foreach my $node ($nodes->get_nodelist) {
print "Got node ", $node->name, "
";
}
$document->validate('/x:html//x:a[@href]') or die "Invalid XPath expression";
DESCRIPTION
This class wraps an XML document with its corresponding meta information (namespaces, XPath context, document node, etc).
It inherits from Glib::Object.
PROPERTIES
The following properties are defined:
source
The source of the document. In most cases this will be a path or an URI pointing to the document.
type
The type of document 'xml' or 'html'.
documentNode
The document's main node (an instance of XML::LibXML::Node).
xpath
The XPath conext to be used with the document.
namespaces
An hashref with the namespaces registered in the document.
METHODS
The package defines the following methods:
new_from_file
Creates a new instance from a file (an URI should also be valid).
Parameters:
$source: the source of the document, this can be a filename or an URI.
$type: the type of document: C<xml> or C<html>.
new_from_string
Creates a new instance from a string.
Parameters:
$content: the contents of the document.
$type: the type of document: C<xml> or C<html>.
empty
Returns an empty document.
source
The source of the document: most likely a file path or an URI.
type
The type of document: xml or html.
namespaces
Returns the namespaces declared in the document. The namespaces are returned in a hashref where the URIs are used as a key and the prefix
as a value.
documentNode
Returns the document's node (an instance of XML::LibXML::Document).
xpath
Returns the XPath context (an instance of XML::LibXML::XPathContext) that includes the namespaces declared in the document. This is the
context used to execute all XPath queries.
find
Runs the given XPath query on the document and returns the results. The results could be a node list or a single value like a boolean, a
number or a scalar if an expression is passed. This method always return its values in scalar context.
This method croaks if the expression can't be evaluated.
Parameters:
$xpath: the XPath expression to execute.
validate
Validates the syntax of the given XPath query. The syntax is validated within a context that has the same namespaces as the ones defined in
the current XML document.
NOTE: This method can't validate if undefined functions or variables are used.
Parameters:
$xpath: the XPath expression to validate.
get_prefixed_name
Returns the node name by prefixing it with our prefixes in the case where namespaces are used.
