Detailed Description

Wrapper class for XML parsing with TinyXML.

This is a wrapper class for XML handling with TinyXML. It is read only and supports trivial XML parsing.

Constructor & Destructor Documentation

XMLNode()

XMLNode::XMLNode	(	const std::string &	_filename,
		const std::string &	_desiredNode
	)

Construct an XML node object from an XML file.

Parameters

_filename	XML Filename
_desiredNode	Desired XML Node to make root of tree

Will throw ParseException when _desiredNode cannot be found or _filename is poorly formed input

Member Function Documentation

Read() [1/4]

template<typename T >

T XMLNode::Read	(	const std::string &	_name,
		const bool	_req,
		const T &	_default,
		const T &	_min,
		const T &	_max,
		const std::string &	_desc
	)

Read XML attribute.

Template Parameters

T	Type of attribute

Parameters

_name	Name of attribute
_req	Is attribute required
_default	Default value of attribute
_min	Minimum value of attribute
_max	Maximum value of attribute
_desc	Description of attribute

Returns

Value of attribute

Reads XML attribute value with _name. If _req is specified and no attribute is given, _default is returned, otherwise input value is required to be in the range [_min, _max]. Otherwise, an error is reported and _desc is shown to the user.

Read() [2/4]

bool XMLNode::Read	(	const std::string &	_name,
		const bool	_req,
		const bool	_default,
		const std::string &	_desc
	)

Read XML boolean attribute

Parameters

_name	Name of attribute
_req	Is attribute required
_default	Default value of attribute
_desc	Description of attribute

Returns

Value of attribute

Reads XML attribute value with _name. If _req is specified and no attribute is given, _default is returned. Otherwise, an error is reported and _desc is shown to the user.

Read() [3/4]

std::string XMLNode::Read	(	const std::string &	_name,
		const bool	_req,
		const char *	_default,
		const std::string &	_desc
	)

Read XML string attribute

Returns

Value of attribute

Calls string version of function to avoid confusion with bool -> const char* conversion in compile.

Read() [4/4]

std::string XMLNode::Read	(	const std::string &	_name,
		const bool	_req,
		const std::string &	_default,
		const std::string &	_desc
	)

Read XML string attribute

Parameters

_name	Name of attribute
_req	Is attribute required
_default	Default value of attribute
_desc	Description of attribute

Returns

Value of attribute

Reads XML attribute value with _name. If _req is specified and no attribute is given, _default is returned. Otherwise, an error is reported and _desc is shown to the user.

WarnAll()

void XMLNode::WarnAll

(

const bool

_warningsAsErrors = false

)

Report warnings for XML tree rooted at this node

Parameters

_warningsAsErrors

True will throw exceptions for warnings

To be called after parsing phase. This will report warnings throughout entire XML document. Should only be called on root XML node. Warnings to be reported:

• unknown/unparsed nodes
• unrequested attribues

Where()

std::string XMLNode::Where

(

)

const

Generate string describing where the node is

Returns

String representing where node is

To be used with PMPLExceptions, specifically ParseException. Gives string with filename, row (line number), and column of XMLNode.
