| 81 | <b>REXML</b><br><br>
|
|---|
| 82 | The first step to accessing an XML document through the REXML parser is creating the object, passing it the XML document.
|
|---|
| 83 | <div class="Code">
|
|---|
| 84 | <br>
|
|---|
| 85 | var xmlDoc = new REXML(strXML);<br>
|
|---|
| 86 | <br>
|
|---|
| 87 | </div>
|
|---|
| 88 | <br>
|
|---|
| 89 | Alternatively, the parser object can be created, the <b>XML</b> property set, and the <b>parse</b> method called.
|
|---|
| 90 | <div class="Code">
|
|---|
| 91 | <br>
|
|---|
| 92 | var xmlDoc = new REXML();<br>
|
|---|
| 93 | ...<br>
|
|---|
| 94 | xmlDoc.XML = strXML;<br>
|
|---|
| 95 | xmlDoc.parse();<br>
|
|---|
| 96 | <br>
|
|---|
| 97 | </div>
|
|---|
| 98 | <br>
|
|---|
| 99 | Once the object is created and XML parsed, the following objects, methods, and properties are used to access the XML.
|
|---|
| 100 | <br>
|
|---|
| 101 | <br>
|
|---|
| 102 | <b>Objects</b>
|
|---|
| 103 | <br>
|
|---|
| 104 | <ul>
|
|---|
| 105 | <b>XMLElement</b>
|
|---|
| 106 | <br>
|
|---|
| 107 | <br>
|
|---|
| 108 | Each node in the XML document is exposed by an XMLElement object.
|
|---|
| 109 | <br>
|
|---|
| 110 | <br>
|
|---|
| 111 | <b>XMLElement Properties</b>
|
|---|
| 112 | <ul>
|
|---|
| 113 | <li>type The type of the element can be:</li>
|
|---|
| 114 | <ul>
|
|---|
| 115 | <li>element</li>
|
|---|
| 116 | <li>text</li>
|
|---|
| 117 | <li>comment</li>
|
|---|
| 118 | <li>pi</li>
|
|---|
| 119 | <li>cdata</li>
|
|---|
| 120 | </ul>
|
|---|
| 121 | <li>name If the type is "element," the tag name</li>
|
|---|
| 122 | <li>childElements[] An array of <b>XMLElement</b>s</li>
|
|---|
| 123 | <li>parentElement The XML Element's parent XML Element</li>
|
|---|
| 124 | <li>text The concatenated value of all text and cdata elements for the element</li>
|
|---|
| 125 | </ul>
|
|---|
| 126 | <b>XMLElement Methods</b>
|
|---|
| 127 | <ul>
|
|---|
| 128 | <li>getText() Returns all text and cdata of all child elements</li>
|
|---|
| 129 | <li>childElement(strElementName) Takes the elements tag name and returns the <b>XMLElement</b> if it's found in the element's children</li>
|
|---|
| 130 | <li>attribute(strAttributeName) Takes the attribute name and returns the value, if found. Returns an empty string if the attribute isn't found.</li>
|
|---|
| 131 | </ul>
|
|---|
| 132 | </ul>
|
|---|
| 133 | <b>Methods</b>
|
|---|
| 134 | <ul>
|
|---|
| 135 | <b>parse()</b>
|
|---|
| 136 | <br>
|
|---|
| 137 | <br>
|
|---|
| 138 | The <b>parse</b> method is called for you if you pass the REXML object a string of XML. Otherwise you must call the parse method before you begin working with the XML.
|
|---|
| 139 | </ul>
|
|---|
| 140 | <b>Properties</b>
|
|---|
| 141 | <ul>
|
|---|
| 142 | <b>rootElement</b>
|
|---|
| 143 | <br>
|
|---|
| 144 | <br>
|
|---|
| 145 | The <b>rootElement</b> property is the entry point, returning the XMLElement for the first node of the document. To work with an XML document the next thing to do after creating the object is to access the rootElement property and use its properties and methods to navigate through the XML.

| 147 | <br>

| 162 | <b>JSXMLBuilder</b><br><br>
|
|---|
| 163 | To manipulate the XML you use the JSXMLBuilder object. Rather than using the structure of the API to give the elements position in the document, the position is given as a vertical and horizontal index (think rows and columns). This makes coding GUIs that manipulate XML a simpler matter, it's the reason there is a separation between the parser that reads and the builder that builds. The specialized roles make REXML a great JavaScript parser, and JSXMLBuilder a great way to manipulate XML through a user interface.
