Detailed Description

A class of utility methods for processing XML files, using Xerces and CodeSynthesis XSD.

Definition at line 70 of file XmlTools.hpp.

Member Function Documentation

std::string XmlTools::EscapeSpaces ( const std::string & rPath )

static

Helper method for URL-escaping spaces in file paths, to avoid confusing Xerces regarding schema locations. Note that this is a very specific fix: it doesn't do general URL-escaping.

Parameters

rPath the path to escape

Returns: path with spaces escaped

Definition at line 442 of file XmlTools.cpp.

void XmlTools::Finalize ( )

static

Must be called after you have finished working with a document returned by the ReadXmlFile methods. An alternative is to instantiate

XmlTools::Finalizer finalizer(false);

just before calling ReadXmlFile, provided that you will do all your processing within that scope. The finalizer object will call Finalize in its destructor.

std::vector< xercesc::DOMElement * > XmlTools::FindElements	(	const xercesc::DOMElement *	pContextElement,
		const std::string &	rPath
	)

static

Returns: all elements matching the given path from this context element.

Parameters

pContextElement	the root element to search from
rPath	where to search. This should be a '/'-separated path of element names.

		const std::vector< std::string > &	rNames,
		std::vector< xercesc::DOMElement * > &	rResults,
		unsigned	depth = `0`
	)

static

Find all elements matching the given path from this context element.

Parameters

pContextElement	the root element to search from
rNames	a list of element names, the first of which is looked for as children of pContextElement; the next as children of those, etc.
rResults	vector to be filled in with matching elements
depth	for managing recursion; should not be provided by users

std::vector< xercesc::DOMElement * > XmlTools::GetChildElements ( const xercesc::DOMElement * pElement )

static

Returns: all the child elements of the given element.

Parameters

pElement the parent element

void XmlTools::PrintNode	(	const std::string &	rMsg,
		xercesc::DOMNode *	pNode,
		bool	showChildren = `false`
	)

static

Display key info about an XML node for debugging.

Parameters

rMsg	message to prepend to the report
pNode	the node to display
showChildren	whether to recursive display the node's children

xsd::cxx::xml::dom::auto_ptr< xercesc::DOMDocument > XmlTools::ReadFileToDomDocument	(	const std::string &	rFileName,
		::xsd::cxx::xml::error_handler< char > &	rErrorHandler,
		const ::xsd::cxx::tree::properties< char > &	rProps,
		bool	validate = `true`
	)

static

Read an XML file into a DOM document. Useful for figuring out what version of the parameters file we're dealing with, so we can construct the right version of the object model.

Based on http://wiki.codesynthesis.com/Tree/FAQ#How_do_I_parse_an_XML_document_to_a_Xerces-C.2B.2B_DOM_document.3F

Requires the Xerces runtime to have been initialised.

Parameters

rFileName	the file to read
rErrorHandler	handler for any parsing errors
rProps	properties that specify fixed schema locations, if wanted
validate	whether to perform schema validation

Returns: Xerces convenience object

		bool	validate = `true`
	)

static

Read an XML file into a DOM document, turning parsing errors into Chaste Exceptions. Handles initialising the Xerces runtime.

Parameters

rFileName	the file to read
rProps	properties that specify fixed schema locations, if wanted
validate	whether to perform schema validation

Returns: Xerces convenience object

xercesc::DOMElement * XmlTools::SetNamespace	(	xercesc::DOMDocument *	pDocument,
		xercesc::DOMElement *	pElement,
		const std::string &	rNamespace
	)

static

Fake having a namespace in older configuration files, by setting the namespace on each element in a tree.

Based on http://wiki.codesynthesis.com/Tree/FAQ#How_do_I_parse_an_XML_document_that_is_missing_namespace_information.3F

Parameters

pDocument	the DOM document containing the tree to be transformed
pElement	the root of the tree to be transformed
rNamespace	the namespace to put elements in

Returns: Xerces element

Fake having a namespace in older configuration files, by setting the namespace on each element in a tree.

Based on http://wiki.codesynthesis.com/Tree/FAQ#How_do_I_parse_an_XML_document_that_is_missing_namespace_information.3F

Parameters

void XmlTools::WrapContentInElement	(	xercesc::DOMDocument *	pDocument,
		xercesc::DOMElement *	pElement,
		const XMLCh *	pNewElementLocalName
	)

static

Wrap the content (children) of an element within a new element. The new element becomes the sole child of the original element.

Note: Doesn't transfer attributes.

Parameters

pDocument	the DOM document containing the tree to be transformed
pElement	the element whose content is to be wrapped
pNewElementLocalName	the local name (i.e. without namespace prefix) of the wrapping element (the namespace of pElement will be used).
