Xacobeo::XS - Functions rewritten in XS. SYNOPSIS
use Xacobeo::XS; Xacobeo::XS->load_text_buffer($textview->get_buffer, $node, $namespaces); Xacobeo::XS->load_tree_store($treeview->get_store, $node, $namespaces); DESCRIPTION
This package provides some functions that are implemented through XS. These functions are much faster than their Perl counterpart. CLASS METHODS
The following class methods are available: load_text_buffer Populates a Gtk2::TextBuffer with the contents of an XML::LibXML::Node. The elements and attributes are displayed with the prefix corresponding to their respective namespaces. The XML document is also displayed with proper syntax highlighting. Parameters: o $buffer The text buffer to fill. Must be an instance of Gtk2::TextBuffer. o $node The node to display in the the text view. Must be an instance of XML::LibXML::Node. o $namespaces The namespaces declared in the document. Must be an hash ref where the keys are the URIs and the values the prefixes of the namespaces. load_tree_store Populates a Gtk2::TreeStore with the contents of an XML::LibXML::Node. The tree will display only the nodes of type element. Furthermore, the elements are displayed with the prefix corresponding to their respective namespaces. Parameters: o $store The text store to fill. Must be an instance of Gtk2::TreeStore. o $node The node to display in the the tree view. Must be an instance of XML::LibXML::Node. o $namespaces The namespaces declared in the document. Must be an hash ref where the keys are the URIs and the values the prefixes of the namespaces. get_node_mark Returns a unique identifier for the given node. Parameters: o $node The node. Must be an instance of XML::LibXML::Node. get_node_path Returns a unique XPath path for the given XML::LibXML::Node. The path will use node names using the right prefixes. Parameters: o $node The node for which the path has to be computed. Must be an instance of XML::LibXML::Node. o $namespaces The namespaces declared in the document. Must be an hash ref where the keys are the URIs and the values the prefixes of the namespaces. AUTHORS
