<a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a> provides an API for serializing (writing) a DOM document out in an XML document.
<p>
The XML data is written to an output stream, the type of which depends on the specific language bindings in use. During serialization of XML data, namespace fixup is done when possible. <p>
<code><a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a></code> accepts any node type for serialization. For nodes of type <code>Document</code> or <code>Entity</code>, well formed XML will be created if possible. The serialized output for these node types is either as a Document or an External Entity, respectively, and is acceptable input for an XML parser. For all other types of nodes the serialized form is not specified, but should be something useful to a human for debugging or diagnostic purposes. Note: rigorously designing an external (source) form for stand-alone node types that don't already have one defined in seems a bit much to take on here. <p>
Within a Document or Entity being serialized, Nodes are processed as follows Documents are written including an XML declaration and a DTD subset, if one exists in the DOM. Writing a document node serializes the entire document. Entity nodes, when written directly by <code>writeNode</code> defined in the <code><a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a></code> interface, output the entity expansion but no namespace fixup is done. The resulting output will be valid as an external entity. Entity References nodes are serializes as an entity reference of the form <code>"&amp;amp;entityName;"</code>) in the output. Child nodes (the expansion) of the entity reference are ignored. CDATA sections containing content characters that can not be represented in the specified output encoding are handled according to the "split-cdata-sections" feature.If the feature is <code>true</code>, CDATA sections are split, and the unrepresentable characters are serialized as numeric character references in ordinary content. The exact position and number of splits is not specified. If the feature is <code>false</code>, unrepresentable characters in a CDATA section are reported as errors. The error is not recoverable - there is no mechanism for supplying alternative characters and continuing with the serialization. All other node types (<a class="el" href="classDOMElement.html" title="By far the vast majority of objects (apart from text) that authors encounter when...">DOMElement</a>, <a class="el" href="classDOMText.html" title="The DOMText interface inherits from DOMCharacterData and represents the textual content...">DOMText</a>, etc.) are serialized to their corresponding XML source form. <p>
Within the character data of a document (outside of markup), any characters that cannot be represented directly are replaced with character references. Occurrences of '&lt;' and '&amp;' are replaced by the predefined entities &amp;lt; and &amp;amp. The other predefined entities (&amp;gt, &amp;apos, etc.) are not used; these characters can be included directly. Any character that can not be represented directly in the output character encoding is serialized as a numeric character reference. <p>
<a class="el" href="classAttributes.html" title="Interface for an element&#39;s attribute specifications.">Attributes</a> not containing quotes are serialized in quotes. <a class="el" href="classAttributes.html" title="Interface for an element&#39;s attribute specifications.">Attributes</a> containing quotes but no apostrophes are serialized in apostrophes (single quotes). <a class="el" href="classAttributes.html" title="Interface for an element&#39;s attribute specifications.">Attributes</a> containing both forms of quotes are serialized in quotes, with quotes within the value represented by the predefined entity &amp;quot;. Any character that can not be represented directly in the output character encoding is serialized as a numeric character reference. <p>
Within markup, but outside of attributes, any occurrence of a character that cannot be represented in the output character encoding is reported as an error. An example would be serializing the element &lt;LaCa�ada/&gt; with the encoding="us-ascii". <p>
When requested by setting the <code>normalize-characters</code> feature on <code><a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a></code>, all data to be serialized, both markup and character data, is W3C Text normalized according to the rules defined in . The W3C Text normalization process affects only the data as it is being written; it does not alter the DOM's view of the document after serialization has completed. <p>
Namespaces are fixed up during serialization, the serialization process will verify that namespace declarations, namespace prefixes and the namespace URIs associated with Elements and <a class="el" href="classAttributes.html" title="Interface for an element&#39;s attribute specifications.">Attributes</a> are consistent. If inconsistencies are found, the serialized form of the document will be altered to remove them. The algorithm used for doing the namespace fixup while seralizing a document is a combination of the algorithms used for lookupNamespaceURI and lookupNamespacePrefix . previous paragraph to be defined closer here. <p>
Any changes made affect only the namespace prefixes and declarations appearing in the serialized data. The DOM's view of the document is not altered by the serialization operation, and does not reflect any changes made to namespace declarations or prefixes in the serialized output. <p>
While serializing a document the serializer will write out non-specified values (such as attributes whose <code>specified</code> is <code>false</code>) if the <code>output-default-values</code> feature is set to <code>true</code>. If the <code>output-default-values</code> flag is set to <code>false</code> and the <code>use-abstract-schema</code> feature is set to <code>true</code> the abstract schema will be used to determine if a value is specified or not, if <code>use-abstract-schema</code> is not set the <code>specified</code> flag on attribute nodes is used to determine if attribute values should be written out. <p>
Ref to Core spec (1.1.9, XML namespaces, 5th paragraph) entity ref description about warning about unbound entity refs. Entity refs are always serialized as &amp;foo;, also mention this in the load part of this spec. <p>
When serializing a document the <a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a> checks to see if the document element in the document is a DOM Level 1 element or a DOM Level 2 (or higher) element (this check is done by looking at the localName of the root element). If the root element is a DOM Level 1 element then the <a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a> will issue an error if a DOM Level 2 (or higher) element is found while serializing. Likewise if the document element is a DOM Level 2 (or higher) element and the <a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a> sees a DOM Level 1 element an error is issued. Mixing DOM Level 1 elements with DOM Level 2 (or higher) is not supported. <p>
<code><a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a></code>s have a number of named features that can be queried or set. The name of <code><a class="el" href="classDOMWriter.html" title="DOMWriter provides an API for serializing (writing) a DOM document out in an XML...">DOMWriter</a></code> features must be valid XML names. Implementation specific features (extensions) should choose an implementation dependent prefix to avoid name collisions. <p>

</dl>
</dd>
<dt><code>"discard-default-content"</code> </dt>
<dd><dl>
<dt><code>true</code> </dt>
<dd>[required] (default ) Use whatever information available to the implementation (i.e. XML schema, DTD, the <code>specified</code> flag on <code>Attr</code> nodes, and so on) to decide what attributes and content should be serialized or not. Note that the <code>specified</code> flag on <code>Attr</code> nodes in itself is not always reliable, it is only reliable when it is set to <code>false</code> since the only case where it can be set to <code>false</code> is if the attribute was created by a Level 1 implementation. </dd>
<dt><code>false</code> </dt>
<dd>[required] Output all attributes and all content. </dd>
</dl>
</dd>
<dt><code>"format-canonical"</code> </dt>
<dd><dl>
<dt><code>true</code> </dt>
<dd>[optional] This formatting writes the document according to the rules specified in . Setting this feature to true will set the feature "format-pretty-print" to false. </dd>
<dt><code>false</code> </dt>
<dd>[required] (default) Don't canonicalize the output. </dd>
</dl>
</dd>
<dt><code>"format-pretty-print"</code> </dt>
<dd><dl>
<dt><code>true</code> </dt>
<dd>[optional] Formatting the output by adding whitespace to produce a pretty-printed, indented, human-readable form. The exact form of the transformations is not specified by this specification. Setting this feature to true will set the feature "format-canonical" to false. </dd>
