The idea is that one defines methods for different classes of the <code>.state</code> argument and dispatch to different methods based on that argument. The functions represent the different SAX events. </p> <h3>Usage</h3> <pre> startElement.SAX(name, atts, .state = NULL) endElement.SAX(name, .state = NULL) comment.SAX(content, .state = NULL) processingInstruction.SAX(target, content, .state = NULL) text.SAX(content, .state = NULL) entityDeclaration.SAX(name, base, sysId, publicId, notationName, .state = NULL) .InitSAXMethods(where = "package:XML") </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>name</code></td> <td> <p>the name of the XML element or entity being declared</p> </td></tr> <tr valign="top"><td><code>atts</code></td> <td> <p>named character vector of XML attributes</p> </td></tr> <tr valign="top"><td><code>content</code></td> <td> <p>the value/string in the processing instruction or comment</p> </td></tr> <tr valign="top"><td><code>target</code></td> <td> <p>the target of the processing instruction, e.g. the R in <code><?R....></code></p> </td></tr> <tr valign="top"><td><code>base</code></td> <td> <p>x</p> </td></tr> <tr valign="top"><td><code>sysId</code></td> <td> <p>the system identifier for this entity</p> </td></tr> <tr valign="top"><td><code>publicId</code></td> <td> <p>the public identifier for the entity</p> </td></tr> <tr valign="top"><td><code>notationName</code></td> <td> <p>name of the notation specification</p> </td></tr> <tr valign="top"><td><code>.state</code></td> <td> <p>the state object on which the user-defined methods should dispatch.</p> </td></tr> <tr valign="top"><td><code>where</code></td> <td> <p>the package in which the class and method definitions should be defined. This is almost always unspecified.</p> </td></tr> </table> <h3>Value</h3> <p>Each method should return the (potentially modified) state value. </p> <h3>Note</h3> <p> This no longer requires the Expat XML parser to be installed. Instead, we use libxml's SAX parser.</p> <h3>Author(s)</h3> <p>Duncan Temple Lang</p> <h3>References</h3> <p><a href="http://www.w3.org/XML">http://www.w3.org/XML</a>, <a href="http://www.xmlsoft.org">http://www.xmlsoft.org</a></p> <h3>See Also</h3> <p><code><a href="xmlEventParse.html">xmlEventParse</a></code> </p> <hr /><div style="text-align: center;">[Package <em>XML</em> version 3.99-0.3 <a href="00Index.html">Index</a>]</div> </body></html>
