org.eclipse.wst.xml.core.internal.contentmodel.modelquery.ModelQuery
This class provides an interface for performing higher level queries based on a xml model (DOM) and one or more associated content models (CMDocument). The queries provided can be organized into three groups: 1) DOM Node to CMNode mapping Given a grammatically valid DOM Node the corresponding CMNode can be determined. (i.e. Element -> CMElementDeclaration, Attr -> CMAttributeDeclaration, CharacterData -> CMDataType) 2) DOM editing tests ("Can I do this?") Questions such as canInsert, canRemove, canReplace can assist in the editing of a DOM. The validityChecking argument determines the strictness of the validity testing that occurs. - VALIDITY_NONE : The current content of the Element is ignored. Only the content model is considered. This is most useful for codeassist related queries. - VALIDITY_STRICT : The current content of the Element is considered. Returns true only if the operation preserves content validity. This is useful when DOM editing needs to be constrained to maintain validity. - VALIDITY_PARTIAL : Some optimized compromise between the two options above. 3) DOM editing actions ("What can I do here?") These methods return ModelQueryActions that are relevant at some specified DOM Node. The actions indicate what kinds of DOM Node can be inserted where (at what index).
