Examples of org.apache.axiom.om.OMElement

org.apache.axiom.om.OMElement
A particular kind of node that represents an element infoset information item.
An element has a collection of children, attributes, and namespace declarations. In contrast with DOM, this interface exposes namespace declarations separately from the attributes.
Namespace declarations are either added explicitly using {@link #declareNamespace(String,String)}, {@link #declareDefaultNamespace(String)} or{@link #declareNamespace(OMNamespace)}, or are created implicitly as side effect of other method calls:
- If the element is created with a namespace and no matching namespace declaration is in scope in the location in the tree where the element is created, then an appropriate namespace declaration will be automatically added to the newly created element. The exact rules depend on the method chosen to create the element; see for example {@link OMFactory#createOMElement(QName)}.
- If an attribute with a namespace is added, but no matching namespace declaration is in scope in the element, one is automatically added. See {@link #addAttribute(OMAttribute)} for moredetails.
Thus, creating a new element or adding an attribute preserves the consistency of the object model with respect to namespaces. However, Axiom does not enforce namespace well-formedness for all possible operations on the object model. E.g. moving an element from one location in the tree to another one may cause the object model to loose its namespace well-formedness. In that case it is possible that the object model contains elements or attributes with namespaces for which no corresponding namespace declarations are in scope.
Fortunately, loosing namespace well-formedness has only very limited impact:
- If namespace well-formedness is lost, the string to {@link QName} resolution for attributevalues and element content may be inconsistent, i.e. {@link #resolveQName(String)}, {@link #getTextAsQName()} and {@link OMText#getTextAsQName()} may return incorrect results.However, it should be noted that these methods are most relevant for object model instances that have been loaded from existing documents or messages. These object models are guaranteed to be well-formed with respect to namespaces (unless they have been modified after loading).
- During serialization, Axiom will automatically repair any namespace inconsistencies. It will add necessary namespace declarations to the output document where they are missing in the object model and generate modified namespace declarations where the original ones in the object model are inconsistent. It will also omit redundant namespace declarations. Axiom guarantees that in the output document, every element and attribute (and {@link OMText} instance with a{@link QName} value) will have the same namespace URI as in the object model, thus preserving theintended semantics of the document. On the other hand, the namespace prefixes used in the output document may differ from the ones in the object model.
- More precisely, Axiom will always make sure that any {@link OMElement} or {@link OMAttribute}node will keep the namespace URI that has been assigned to the node at creation time, unless the namespace is explicitly changed using {@link #setNamespace(OMNamespace)} or{@link OMAttribute#setOMNamespace(OMNamespace)}. [TODO: this is currently not entirely true; see WSCOMMONS-517]
