Constructor & Destructor Documentation

zypp::parser::LibXMLHelper::LibXMLHelper

(

)

The default constructor will return an object that does not look into the namespace properties of the nodes.

Later, another constructor will be added that takes a list of namespaces as parameters (and maybe also character encoding information), and all nodes of different namespaces will be ignored (i.e., attributes will not be used, and for elements in different namespaces isElement() will return false).

		const std::string &	defaultValue = std::string()
	)			const

Fetch an attribute.

Parameters:

	node	the xmlNode
	name	name of the attribute

std::string zypp::parser::LibXMLHelper::content

(

xmlNode *

nodePtr

)

const

The TEXT content of the node and all child nodes Read the value of a node, this can be either the text carried directly by this node if it's a TEXT node or the aggregate string of the values carried by this node child's (TEXT and ENTITY_REF). Entity references are substituted.

Parameters:

nodePtr

the xmlNode

Returns:

the content
