findByClass() [1/2]

template<class T , class C >

bool findByClass ( const T &  t, const C &  cls, SearchXML::path_list_t &  result, const path_t &  path = path_t()  )

inlinestatic

Finds elements recursively in an XML structure by class name supplied as an enumeration type.

Template Parameters

V	- XML tree
C	- enum type, for which a unique (static) EnumDict has been detected.

Parameters

path	- starting point

findByClass() [2/2]

template<class T , class C >

bool findByClass ( const T &  t, const C &  cls, std::list< typename T::path_elem_t > &  result  )

static

Finds child elements in an XML structure by class name.

Immediate descendants.

Template Parameters

V	- XML tree

In a way, this is a forward definition – this could also be in TreeXMLutilities.

findById() [1/2]

template<class T >

bool findById ( const T &  tree, const std::string &  tag, SearchXML::path_list_t &  result, const path_t &  path = path_t()  )

static

Find the occurrence(s) of given ID using recursive breath-first search.

By definition, id attributes should be unique. This function nevertheless returns a list if user wants to handle more than one elements found.

Parameters

tree	- source element,
id	- id attribute to be searched for
result	- path of pointing to
path	- start path for the search.

Returns

- true, if an element was found.

findById() [2/2]

template<class V >

static bool findById ( const V &  tree, const std::string &  tag, typename V::path_t &  result, const typename V::path_t &  path = path_t()  )

static

Find the first occurrence of given id using recursive breath-first search.

By definition, id attributes should be unique.

Parameters

tree	- source element,
id	- id attribute to be searched for
result	- path of the element with required ID, if found.
path	- start path for the search.

Returns

- true, if an element was found.

findByTag() [1/2]

template<class T , class N >

bool findByTag	(	const T &	t,
		const N &	tag,
		SearchXML::path_list_t &	result,
		const path_t &	path
	)

Template Parameters

Tree

findByTag() [2/2]

template<class T , class E >

static bool findByTag ( const T &  tree, const E &  tag, path_list_t &  result, const path_t &  path = path_t()  )

static

Find all the occurrences of given tag type using recursive breath-first search. This is a "forward definition" – this could also be in TreeXMLutilities.

findByTags() [1/2]

template<class T , class N >

bool findByTags	(	const T &	t,
		const std::set< N > &	tags,
		SearchXML::path_list_t &	result,
		const SearchXML::path_t &	path
	)

Template Parameters

Tree

findByTags() [2/2]

template<class T , class E >

static bool findByTags ( const T &  tree, const std::set< E > &  tags, path_list_t &  result, const path_t &  path = path_t()  )

static

"Forward definition"

Template Parameters

V	- XML tree
