Detailed Description

The element is a container class. It has a value, the element name, and can contain other elements, text, comments, and unknowns. Elements also contain an arbitrary number of attributes.

Member Function Documentation

bool tinyxml2::XMLElement::Accept ( XMLVisitor * visitor ) const [virtual]

Accept a hierarchical visit of the nodes in the TinyXML-2 DOM. Every node in the XML tree will be conditionally visited and the host will be called back via the XMLVisitor interface.

This is essentially a SAX interface for TinyXML-2. (Note however it doesn't re-parse the XML for the callbacks, so the performance of TinyXML-2 is unchanged by using this interface versus any other.)

The interface has been based on ideas from:

Which are both good references for "visiting".

An example of using Accept():

    	XMLPrinter printer;
    	tinyxmlDoc.Accept( &printer );
    	const char* xmlcstr = printer.CStr();

Implements tinyxml2::XMLNode.

const char * tinyxml2::XMLElement::Attribute	(	const char *	name,
		const char *	value = `0`
	)		const

Given an attribute name, Attribute() returns the value for the attribute of that name, or null if none exists. For example:

    	const char* value = ele->Attribute( "foo" );

The 'value' parameter is normally null. However, if specified, the attribute will only be returned if the 'name' and 'value' match. This allow you to write code:

    	if ( ele->Attribute( "foo", "bar" ) ) callFooIsBar();

rather than:

    	if ( ele->Attribute( "foo" ) ) {
    		if ( strcmp( ele->Attribute( "foo" ), "bar" ) == 0 ) callFooIsBar();
    	}

const char * tinyxml2::XMLElement::GetText ( ) const

Convenience function for easy access to the text inside an element. Although easy and concise, GetText() is limited compared to getting the XMLText child and accessing it directly.

If the first child of 'this' is a XMLText, the GetText() returns the character string of the Text node, else null is returned.

This is a convenient method for getting the text of simple contained text:

    	<foo>This is text</foo>
    		const char* str = fooElement->GetText();

'str' will be a pointer to "This is text".

Note that this function can be misleading. If the element foo was created from this XML:

    		<foo><b>This is text</b></foo>

then the value of str would be null. The first child node isn't a text node, it is another element. From this XML:

    		<foo>This is <b>text</b></foo>

GetText() will return "This is ".

Definition at line 1415 of file tinyxml2.cpp.

int tinyxml2::XMLElement::IntAttribute ( const char * name ) const [inline]

Given an attribute name, IntAttribute() returns the value of the attribute interpreted as an integer. 0 will be returned if there is an error. For a method with error checking, see QueryIntAttribute()

Definition at line 1205 of file tinyxml2.h.

const char* tinyxml2::XMLElement::Name ( ) const [inline]

Definition at line 1659 of file tinyxml2.cpp.

int tinyxml2::XMLElement::QueryAttribute	(	const char *	name,
		int *	value
	)		const `[inline]`

Given an attribute name, QueryAttribute() returns XML_NO_ERROR, XML_WRONG_ATTRIBUTE_TYPE if the conversion can't be performed, or XML_NO_ATTRIBUTE if the attribute doesn't exist. It is overloaded for the primitive types, and is a generally more convenient replacement of QueryIntAttribute() and related functions.

If successful, the result of the conversion will be written to 'value'. If not successful, nothing will be written to 'value'. This allows you to provide default value:

    	int value = 10;
    	QueryAttribute( "foo", &value );		// if "foo" isn't found, value will still be 10

XMLError tinyxml2::XMLElement::QueryIntText ( int * ival ) const

Convenience method to query the value of a child text node. This is probably best shown by example. Given you have a document is this form:

    		<point>
    			<x>1</x>
    			<y>1.4</y>
    		</point>

The QueryIntText() and similar functions provide a safe and easier way to get to the "value" of x and y.

    		int x = 0;
    		float y = 0;	// types of x and y are contrived for example
    		const XMLElement* xElement = pointElement->FirstChildElement( "x" );
    		const XMLElement* yElement = pointElement->FirstChildElement( "y" );
    		xElement->QueryIntText( &x );
    		yElement->QueryFloatText( &y );

Returns:: XML_SUCCESS (0) on success, XML_CAN_NOT_CONVERT_TEXT if the text cannot be converted to the requested type, and XML_NO_TEXT_NODE if there is no child text to query.
