Member Function Documentation

◆ AppendChildNode()

virtual std::shared_ptr< IXmlNodeRw > libCZI::IXmlNodeWrite::AppendChildNode ( const char * name )

pure virtual

Appends a child node with the specified name.

Parameters

name	The name of the node to add.

Returns: The newly added node.

◆ GetChildNode() [1/2]

virtual std::shared_ptr< IXmlNodeRw > libCZI::IXmlNodeWrite::GetChildNode ( const char * path )

pure virtual

Gets an existing child node. The path is specified as node-names separated by slashes. A path "A/B/C" selects (or creates) a node-structure like this

<A>
  <B>
    <C/>
  </B>
</A>

Attributes can be specified with a node, in the form 'NodeName[attr1=abc,attr2=xyz]'. This will search for nodes with the specified attributes, and if not found, create one. In this example "A/B[Id=ab,Name=xy]/C" we will get

<A>
  <B Id="ab" Name="xy">
    <C/>
  </B>
</A>

It is also possible to specify a number inside the square brackets, which indicates that the n-th element is to be selected. This index is zero-based. In this example

<A>
  <B Id="ab" Name="xy">
    <C Id="first"></C>
    <C Id="second"></C>
    <C Id="third"></C>
  </B>
</A>

the path "A/B/C[1]" will select the second node of name 'C'. If the path does not exist, then a nullptr is returned. This method may throw an exception if the path is not well-formed and syntactically valid.

Parameters

path	The path (in UTF8-encoding).

Returns: The existing node conforming to the path if it exists, null otherwise.

◆ GetChildNode() [2/2]

std::shared_ptr< IXmlNodeRw > libCZI::IXmlNodeWrite::GetChildNode ( const std::string & path )

inline

Gets a child node for the specified path.

Parameters

path	Path of the childnode (in UTF8-encoding).

Returns: The child node.

◆ GetOrCreateChildNode() [1/2]

virtual std::shared_ptr< IXmlNodeRw > libCZI::IXmlNodeWrite::GetOrCreateChildNode ( const char * path )

pure virtual

Gets or create a child node. The path is specified as node-names separated by slashes. A path "A/B/C" selects (or creates) a node-structure like this

<A>
  <B>
    <C/>
  </B>
</A>

Attributes can be specified with a node, in the form 'NodeName[attr1=abc,attr2=xyz]'. This will search for nodes with the specified attributes, and if not found, create one. In this example "A/B[Id=ab,Name=xy]/C" we will get

<A>
  <B Id="ab" Name="xy">
    <C/>
  </B>
</A>

Parameters

path	The path (in UTF8-encoding).

Returns: Either an existing node or a newly created one.

◆ GetOrCreateChildNode() [2/2]

std::shared_ptr< IXmlNodeRw > libCZI::IXmlNodeWrite::GetOrCreateChildNode ( const std::string & path )

inline

Gets or create a child node. The path is specified as node-names separated by slashes. At path "A/B/C" selects (or creates) a node-structure like this

<A>
  <B>
    <C/>
  </B>
</A>

Attributes can be specified with a node, in the form 'NodeName[attr1=abc,attr2=xyz]'. This will search for nodes with the specified attributes, and if not found, create one. In this example "A/B[Id=ab,Name=xy]/C" we will get

<A>
  <B Id="ab" Name="xy">
    <C/>
  </B>
</A>

Parameters

path The path.

Returns: Either an existing node or a newly created one.

◆ RemoveAttribute()

virtual bool libCZI::IXmlNodeWrite::RemoveAttribute ( const char * name )

pure virtual

Removes the attribute with the specified name. In case that there a multiple attributes with the specified name, then only the first is removed.

Parameters

name	The name of the attribute to be removed.

Returns: True if the attribute was found and successfully removed; false otherwise (i.e. if it did not exist).

◆ RemoveChild()

virtual bool libCZI::IXmlNodeWrite::RemoveChild ( const char * name )

pure virtual

Removes the child node with the specified name. In case that there a multiple children with the specified name, then only the first is removed.

Parameters

name	The name of the node to be removed.

Returns: True if the node was found and successfully removed; false otherwise (i.e. if it did not exist).

◆ SetAttribute() [1/2]

virtual void libCZI::IXmlNodeWrite::SetAttribute	(	const char *	name,
		const char *	value
	)

pure virtual

Sets the attribute with the specified name to the specified value.

Parameters

name	The name of the attribute (as UTF8-encoded string).
value	The value (as UTF8-encoded string).

◆ SetAttribute() [2/2]

virtual void libCZI::IXmlNodeWrite::SetAttribute	(	const wchar_t *	name,
		const wchar_t *	value
	)

pure virtual

Sets the attribute with the specified name to the specified value.

Parameters

name	The name of the attribute.
value	The value.

◆ SetValue() [1/4]

virtual void libCZI::IXmlNodeWrite::SetValue ( const char * str )

pure virtual

Sets the node value - which is specified as an UTF8-string.

Parameters

str	The UTF8-encoded string.

◆ SetValue() [2/4]

void libCZI::IXmlNodeWrite::SetValue ( const std::string & str )

inline

Sets the node value - which is specified as an UTF8-string.

Parameters

str	The UTF8-encoded string.

◆ SetValue() [3/4]

void libCZI::IXmlNodeWrite::SetValue ( const std::wstring & str )

inline
