21 * An interface to an object that is able to build, or augment, a DOM tree
22 * from various input sources.
23 * <p> <code>LSParser</code> provides an API for parsing XML and building the
24 * corresponding DOM document structure. A <code>LSParser</code> instance
25 * can be obtained by invoking the
26 * <code>DOMImplementationLS.createLSParser()</code> method.
27 * <p> As specified in [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>DOM Level 3 Core</a>]
28 * , when a document is first made available via the LSParser:
29 * <ul>
30 * <li> there will
31 * never be two adjacent nodes of type NODE_TEXT, and there will never be
32 * empty text nodes.
33 * </li>
34 * <li> it is expected that the <code>value</code> and
35 * <code>nodeValue</code> attributes of an <code>Attr</code> node initially
36 * return the <a href='http://www.w3.org/TR/2004/REC-xml-20040204#AVNormalize'>XML 1.0
37 * normalized value</a>. However, if the parameters "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-validate-if-schema'>
38 * validate-if-schema</a>" and "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-datatype-normalization'>
39 * datatype-normalization</a>" are set to <code>true</code>, depending on the attribute normalization
40 * used, the attribute values may differ from the ones obtained by the XML
41 * 1.0 attribute normalization. If the parameters "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-datatype-normalization'>
42 * datatype-normalization</a>" is set to <code>false</code>, the XML 1.0 attribute normalization is
43 * guaranteed to occur, and if the attributes list does not contain
44 * namespace declarations, the <code>attributes</code> attribute on
45 * <code>Element</code> node represents the property <b>[attributes]</b> defined in [<a href='http://www.w3.org/TR/2004/REC-xml-infoset-20040204/'>XML Information Set</a>]
46 * .
47 * </li>
48 * </ul>
49 * <p> Asynchronous <code>LSParser</code> objects are expected to also
50 * implement the <code>events::EventTarget</code> interface so that event
51 * listeners can be registered on asynchronous <code>LSParser</code>
52 * objects.
53 * <p> Events supported by asynchronous <code>LSParser</code> objects are:
54 * <dl>
55 * <dt>load</dt>
56 * <dd>
57 * The <code>LSParser</code> finishes to load the document. See also the
58 * definition of the <code>LSLoadEvent</code> interface. </dd>
59 * <dt>progress</dt>
60 * <dd> The
61 * <code>LSParser</code> signals progress as data is parsed. This
62 * specification does not attempt to define exactly when progress events
63 * should be dispatched. That is intentionally left as
64 * implementation-dependent. Here is one example of how an application might
65 * dispatch progress events: Once the parser starts receiving data, a
66 * progress event is dispatched to indicate that the parsing starts. From
67 * there on, a progress event is dispatched for every 4096 bytes of data
68 * that is received and processed. This is only one example, though, and
69 * implementations can choose to dispatch progress events at any time while
70 * parsing, or not dispatch them at all. See also the definition of the
71 * <code>LSProgressEvent</code> interface. </dd>
72 * </dl>
73 * <p ><b>Note:</b> All events defined in this specification use the
74 * namespace URI <code>"http://www.w3.org/2002/DOMLS"</code>.
75 * <p> While parsing an input source, errors are reported to the application
76 * through the error handler (<code>LSParser.domConfig</code>'s "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-error-handler'>
77 * error-handler</a>" parameter). This specification does in no way try to define all possible
78 * errors that can occur while parsing XML, or any other markup, but some
79 * common error cases are defined. The types (<code>DOMError.type</code>) of
80 * errors and warnings defined by this specification are:
81 * <dl>
82 * <dt>
83 * <code>"check-character-normalization-failure" [error]</code> </dt>
84 * <dd> Raised if
85 * the parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-check-character-normalization'>
86 * check-character-normalization</a>" is set to true and a string is encountered that fails normalization
87 * checking. </dd>
88 * <dt><code>"doctype-not-allowed" [fatal]</code></dt>
89 * <dd> Raised if the
90 * configuration parameter "disallow-doctype" is set to <code>true</code>
91 * and a doctype is encountered. </dd>
92 * <dt><code>"no-input-specified" [fatal]</code></dt>
93 * <dd>
94 * Raised when loading a document and no input is specified in the
95 * <code>LSInput</code> object. </dd>
96 * <dt>
97 * <code>"pi-base-uri-not-preserved" [warning]</code></dt>
98 * <dd> Raised if a processing
99 * instruction is encountered in a location where the base URI of the
100 * processing instruction can not be preserved. One example of a case where
101 * this warning will be raised is if the configuration parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-entities'>
102 * entities</a>" is set to <code>false</code> and the following XML file is parsed:
103 * <pre>
104 * <!DOCTYPE root [ <!ENTITY e SYSTEM 'subdir/myentity.ent' ]>
105 * <root> &e; </root></pre>
106 * And <code>subdir/myentity.ent</code>
107 * contains:
108 * <pre><one> <two/> </one> <?pi 3.14159?>
109 * <more/></pre>
110 * </dd>
111 * <dt><code>"unbound-prefix-in-entity" [warning]</code></dt>
112 * <dd> An
113 * implementation dependent warning that may be raised if the configuration
114 * parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-namespaces'>
115 * namespaces</a>" is set to <code>true</code> and an unbound namespace prefix is
116 * encountered in an entity's replacement text. Raising this warning is not
117 * enforced since some existing parsers may not recognize unbound namespace
118 * prefixes in the replacement text of entities. </dd>
119 * <dt>
120 * <code>"unknown-character-denormalization" [fatal]</code></dt>
121 * <dd> Raised if the
122 * configuration parameter "ignore-unknown-character-denormalizations" is
123 * set to <code>false</code> and a character is encountered for which the
124 * processor cannot determine the normalization properties. </dd>
125 * <dt>
126 * <code>"unsupported-encoding" [fatal]</code></dt>
127 * <dd> Raised if an unsupported
128 * encoding is encountered. </dd>
129 * <dt><code>"unsupported-media-type" [fatal]</code></dt>
130 * <dd>
131 * Raised if the configuration parameter "supported-media-types-only" is set
132 * to <code>true</code> and an unsupported media type is encountered. </dd>
133 * </dl>
134 * <p> In addition to raising the defined errors and warnings, implementations
135 * are expected to raise implementation specific errors and warnings for any
