As each node is 286N/A * examined, it may be modified or removed, or the entire parse may be 286N/A * <p> At the time any of the filter methods are called by the parser, the 286N/A * owner Document and DOMImplementation objects exist and are accessible. 286N/A * The document element is never passed to the <code>LSParserFilter</code> 286N/A * methods, i.e. it is not possible to filter out the document element. 286N/A * <code>Document</code>, <code>DocumentType</code>, <code>Notation</code>, 286N/A * <code>Entity</code>, and <code>Attr</code> nodes are never passed to the 286N/A * <code>acceptNode</code> method on the filter. The child nodes of an 286N/A * <code>EntityReference</code> node are passed to the filter if the 286N/A * entities</a>", unexpanded entity reference nodes are never discarded and are always 286N/A * passed to the filter. 286N/A * <p> All validity checking while parsing a document occurs on the source 286N/A * document as it appears on the input stream, not on the DOM document as it 286N/A * is built in memory. With filters, the document in memory may be a subset 286N/A * of the document on the stream, and its validity may have been affected by 286N/A * <p> All default attributes must be present on elements when the elements 286N/A * are passed to the filter methods. All other default content must be 286N/A * passed to the filter methods. 286N/A * <p> DOM applications must not raise exceptions in a filter. The effect of 286N/A * throwing exceptions from a filter is DOM implementation dependent. 286N/Aand Save Specification</a>. 286N/A // Constants returned by startElement and acceptNode 286N/A * Reject the node and its children. 286N/A * Skip this single node. The children of this node will still be 286N/A * Interrupt the normal processing of the document. 286N/A * The parser will call this method after each <code>Element</code> start 286N/A * tag has been scanned, but before the remainder of the 286N/A * <code>Element</code> is processed. The intent is to allow the 286N/A * element, including any children, to be efficiently skipped. Note that 286N/A * only element nodes are passed to the <code>startElement</code> 286N/A * <br>The element node passed to <code>startElement</code> for filtering 286N/A * will include all of the Element's attributes, but none of the 286N/A * children nodes. The Element may not yet be in place in the document 286N/A * being constructed (it may not have a parent node.) 286N/A * <br>A <code>startElement</code> filter function may access or change 286N/A * the attributes for the Element. Changing Namespace declarations will 286N/A * have no effect on namespace resolution by the parser. 286N/A * <br>For efficiency, the Element node passed to the filter may not be 286N/A * the same one as is actually placed in the tree if the node is 286N/A * accepted. And the actual node (node object identity) may be reused 286N/A * during the process of reading in and filtering a document. 286N/A * @param elementArg The newly encountered element. At the time this 286N/A * method is called, the element is incomplete - it will have its 286N/A * attributes, but no children. 286N/A * <li> <code>FILTER_ACCEPT</code> if the <code>Element</code> should 286N/A * be included in the DOM document being built. 286N/A * <code>FILTER_REJECT</code> if the <code>Element</code> and all of 286N/A * its children should be rejected. 286N/A * <li> <code>FILTER_SKIP</code> if the 286N/A * <code>Element</code> should be skipped. All of its children are 286N/A * inserted in place of the skipped <code>Element</code> node. 286N/A * <code>FILTER_INTERRUPT</code> if the filter wants to stop the 286N/A * processing of the document. Interrupting the processing of the 286N/A * document does no longer guarantee that the resulting DOM tree is 286N/A * XML well-formed. The <code>Element</code> is rejected. 286N/A * any other values will result in unspecified behavior. 286N/A * This method will be called by the parser at the completion of the 286N/A * parsing of each node. The node and all of its descendants will exist 286N/A * and be complete. The parent node will also exist, although it may be 286N/A * incomplete, i.e. it may have additional children that have not yet 286N/A * been parsed. Attribute nodes are never passed to this function. 286N/A * <br>From within this method, the new node may be freely modified - 286N/A * children may be added or removed, text nodes modified, etc. The state 286N/A * of the rest of the document outside this node is not defined, and the 286N/A * affect of any attempt to navigate to, or to modify any other part of 286N/A * the document is undefined. 286N/A * <br>For validating parsers, the checks are made on the original 286N/A * document, before any modification by the filter. No validity checks 286N/A * are made on any document modifications made by the filter. 286N/A * <br>If this new node is rejected, the parser might reuse the new node 286N/A * and any of its descendants. 286N/A * @param nodeArg The newly constructed element. At the time this method 286N/A * is called, the element is complete - it has all of its children 286N/A * (and their children, recursively) and attributes, and is attached 286N/A * as a child to its parent. 286N/A * <li> <code>FILTER_ACCEPT</code> if this <code>Node</code> should 286N/A * be included in the DOM document being built. 286N/A * <code>FILTER_REJECT</code> if the <code>Node</code> and all of its 286N/A * children should be rejected. 286N/A * <li> <code>FILTER_SKIP</code> if the 286N/A * <code>Node</code> should be skipped and the <code>Node</code> 286N/A * should be replaced by all the children of the <code>Node</code>. 286N/A * <code>FILTER_INTERRUPT</code> if the filter wants to stop the 286N/A * processing of the document. Interrupting the processing of the 286N/A * document does no longer guarantee that the resulting DOM tree is 286N/A * XML well-formed. The <code>Node</code> is accepted and will be the 286N/A * last completely parsed node. 286N/A * Tells the <code>LSParser</code> what types of nodes to show to the 286N/A * method <code>LSParserFilter.acceptNode</code>. If a node is not shown 286N/A * to the filter using this attribute, it is automatically included in 286N/A * the DOM document being built. See <code>NodeFilter</code> for 286N/A * definition of the constants. The constants <code>SHOW_ATTRIBUTE</code> 286N/A * , <code>SHOW_DOCUMENT</code>, <code>SHOW_DOCUMENT_TYPE</code>, 286N/A * <code>SHOW_NOTATION</code>, <code>SHOW_ENTITY</code>, and 286N/A * <code>SHOW_DOCUMENT_FRAGMENT</code> are meaningless here. Those nodes 286N/A * will never be passed to <code>LSParserFilter.acceptNode</code>.
