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

const char* TiXmlElement::Attribute	(	const char *	name,
		double *	d
	)			const

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

If the attribute exists and can be converted to an double, the double value will be put in the return 'd', if 'd' is non-null.

const char* TiXmlElement::Attribute	(	const char *	name,
		int *	i
	)			const

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

If the attribute exists and can be converted to an integer, the integer value will be put in the return 'i', if 'i' is non-null.

const char* TiXmlElement::GetText

(

)

const

Convenience function for easy access to the text inside an element.

Although easy and concise, GetText() is limited compared to getting the TiXmlText child and accessing it directly.

If the first child of 'this' is a TiXmlText, 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 ".

WARNING: GetText() accesses a child node - don't become confused with the similarly named TiXmlHandle::Text() and TiXmlNode::ToText() which are safe type casts on the referenced node.

virtual void TiXmlElement::Print	(	FILE *	cfile,
		int	depth
	)			const [virtual]

All TinyXml classes can print themselves to a filestream or the string class (TiXmlString in non-STL mode, std::string in STL mode.

) Either or both cfile and str can be null.

This is a formatted print, and will insert tabs and newlines.

(For an unformatted stream, use the << operator.)

Implements TiXmlBase.

int TiXmlElement::QueryIntAttribute	(	const char *	name,
		int *	_value
	)			const

QueryIntAttribute examines the attribute - it is an alternative to the Attribute() method with richer error checking.

If the attribute is an integer, it is stored in 'value' and the call returns TIXML_SUCCESS. If it is not an integer, it returns TIXML_WRONG_TYPE. If the attribute does not exist, then TIXML_NO_ATTRIBUTE is returned.

template<typename T>

int TiXmlElement::QueryValueAttribute	(	const std::string &	name,
		T *	outValue
	)			const [inline]

Template form of the attribute query which will try to read the attribute into the specified type.

Very easy, very powerful, but be careful to make sure to call this with the correct type.

NOTE: This method doesn't work correctly for 'string' types.

Returns:

TIXML_SUCCESS, TIXML_WRONG_TYPE, or TIXML_NO_ATTRIBUTE

void TiXmlElement::SetAttribute	(	const char *	name,
		int	value
	)

Sets an attribute of name to a given value.

The attribute will be created if it does not exist, or changed if it does.

void TiXmlElement::SetAttribute	(	const char *	name,
		const char *	_value
	)

Sets an attribute of name to a given value.

The attribute will be created if it does not exist, or changed if it does.

void TiXmlElement::SetDoubleAttribute	(	const char *	name,
		double	value
	)

Sets an attribute of name to a given value.

The attribute will be created if it does not exist, or changed if it does.
