34 <p>This is my XML parser, based on the original:</p>
35 <ul>
36 <li>No html mode - this is pure xml</li>
37 <li>Illegal attributes and element names are errors</li>
38 <li>Attributes must have a value</li>
39 <li>XML declaration supported (e.g.: <b>&lt;?xml version="1.0" encoding="utf-8" standalone="no" ?&gt;</b>)</li>
40 <li>CDATA and comment blocks are not indented (except for their start-tag)</li>
41 <li>Better handling of errors per line with the state object - provides good infrastructure for extending it</li>
42 </ul>
43
44 <p>What's missing:</p>
45 <ul>
46 <li>Make sure only a single root element exists at the document level</li>
47 <li>Multi-line attributes should NOT indent</li>
48 <li>Start tags are not painted red when they have no matching end tags (is this really wrong?)</li>
49 </ul>
