XML_Node * findNameID	(	const std::string &	nameTarget,
		const std::string &	idTarget
	)		const

This routine carries out a recursive search for an XML node based on both the xml element name and the attribute ID.

If exact matches are found for both fields, the pointer to the matching XML Node is returned.

The ID attribute may be defaulted by setting it to "". In this case the pointer to the first xml element matching the name only is returned.

Parameters

nameTarget	Name of the XML Node that is being searched for
idTarget	"id" attribute of the XML Node that the routine looks for

Returns: Returns the pointer to the XML node that fits the criteria

This algorithm does a lateral search of first generation children first before diving deeper into each tree branch.

This routine carries out a search for an XML node based on both the xml element name and the attribute ID and an integer index.

If exact matches are found for all fields, the pointer to the matching XML Node is returned. The search is only carried out on the current element and the child elements of the current element.

The "id" attribute may be defaulted by setting it to "". In this case the pointer to the first xml element matching the name only is returned.

Parameters

nameTarget	Name of the XML Node that is being searched for
idTarget	"id" attribute of the XML Node that the routine looks for
index	Integer describing the index. The index is an attribute of the form index = "3"

void writeHeader ( std::ostream & s )

void write	(	std::ostream &	s,
		const int	level = `0`,
		int	numRecursivesAllowed = `60000`
	)		const

Write an XML subtree to an output stream.

This is a wrapper around the static routine write_int(). All this does is add an endl on to the output stream. write_int() is fine, but the last endl wasn't being written. It also checks for the special name "–". If found and we are at the root of the xml tree, then the block is skipped and the children are processed. "–" is used to denote the top of the tree.

Parameters

s	ostream to write to
level	Indentation level to work from
numRecursivesAllowed	Number of recursive calls allowed

protected

XML node name of the node.

For example, if we were in the XML_Node where

*       <phase dim="3" id="gas">
*       </phase>
*

Then, this string would be equal to "phase". "dim" and "id" are attributes of the XML_Node.
