Detailed Description

Default implementation of XML elements.

Library: ilog

This class implements the interface IlXmlElementI to provide the basic functionality of an XML element.
Child nodes and attributes are stored in a list.

Member Function Documentation

virtual void IlXmlElement::addAttribute ( IlXmlAttributeI * attribute )

virtual

Adds an attribute to this element.

Parameters

attribute The attribute to be added to this element. The node is responsible for the destruction of this attribute when this element is destroyed. The default implementation deletes this attribute.

Reimplemented from IlXmlElementI.

virtual void IlXmlElement::addChild ( IlXmlNodeI * node )

virtual

Adds a child node to this element.

Parameters

node	The new node that is added to this element. The default implementation deletes this node.

Reimplemented from IlXmlElementI.

virtual IlXmlNodeIteratorI* IlXmlElement::createAttributesIterator ( ) const

virtual

Creates an iterator for the attributes of this element.

Returns: A new iterator for the attributes of this element. The default implementation returns 0.

Reimplemented from IlXmlElementI.

virtual IlXmlNodeIteratorI* IlXmlElement::createChildrenIterator ( ) const

virtual

Creates an iterator for the child nodes of this element.

Returns: A new iterator for the child nodes of this element. The default implementation returns 0.

Reimplemented from IlXmlElementI.

virtual IlBoolean IlXmlElement::doesPreserveWhiteSpaces ( ) const

virtual

Indicates if non-significant white spaces are kept.

Returns: IlTrue if the non-significant white spaces (the ones at the beginning or at the end of the element content) are kept in the element, IlFalse otherwise.

See Also: preserveWhiteSpaces().

Reimplemented from IlXmlElementI.

virtual IlXmlAttributeI* IlXmlElement::getAttribute ( const char * name ) const

virtual

Returns the attribute with the specified name.

Parameters

name	The name of the attribute that is requested.

Returns: The attribute of this element that has a name similar to (in the sense that strcmp defines) name, or 0 if no attribute has this name. The default implementation scans all the attributes that are accessed by the attributes iterator to find a match.

Reimplemented from IlXmlElementI.

IlXmlElement* IlXmlElement::getElement	(	const char *	tagName,
		IlXmlNodeI *	skip = `0`
	)		const

Returns a child element that has a given tag name.

This member function searches a child element of this element that has a tag named tagName. If skip is not null, this member function starts the search after this node.
This member function is very useful when you want to get all the child elements that have a given tag name. Then, for the skip parameter you have to provide the last match that this function has found.

Parameters

tagName	The tag name of the element that is searched in the children of this element.
skip	A pointer to the node after which the search starts.

Returns: A pointer to the element that was found, or 0 if no matching element could be located.

virtual const char* IlXmlElement::getTag ( ) const

virtual

Retrieves the tag name of this element.

Returns: The tag name of this element. The returned string must not be deleted or modified.

Implements IlXmlElementI.

virtual const char* IlXmlElement::getText ( ) const

virtual

Retrieves the content of the first Text node child.

Returns: A string that contains the content of the first Text element of this element, or 0 if there are not any. The user must not modify or delete the returned string.

Reimplemented from IlXmlElementI.

virtual void IlXmlElement::preserveWhiteSpaces ( IlBoolean preserve )

virtual

Forces non-significant white spaces to be kept or dropped.

Parameters

preserve If set to IlTrue, even non-significant white spaces will be kept in the element content.

See Also: doesPreserveWhiteSpaces().

Reimplemented from IlXmlElementI.

virtual void IlXmlElement::storeTag ( char * tag )

virtual

Sets the tag name of this element.

Parameters

tag	The new tag name of this element. The string is not copied before it is stored, but it is deleted (using `delete []`) by the destructor. The default implementation deletes this string and does nothing else with it.

Reimplemented from IlXmlElementI.
