shaman.dom's Issues

Closing span tag written to wrong location

Using version 1.0.1.16 of Shaman.Dom, there is incorrect output when serializing the attached html file "test.html". Create an HtmlDocument instance from this file, then write the HtmlDocument to a new file using the WriteTo() method. You will find that a <span/> closing tag has been added on line 116. This has the effect of placing the two <div> tags on lines 114 and 115 before the <span/> when they should be after the <span/>. View the output file "test.out.html" to see this.

Attribute values are automatically un-escaped

If an attribute in an HTML document contains escaped characters, those characters are un-escaped when the HtmlDocument class builds the DOM. This means that we can't be guaranteed that the DOM will reproduce the original HTML when it is written out using WriteTo().

For example, a tag such as this will be converted into invalid HTML if it is converted into an HtmlNode and then written out:

<meta name="ajs-editor.loader.resources" content="&lt;link type=&quot;text/css&quot; rel=&quot;stylesheet&quot; href=&quot;/s/d41d8cd98f00b204e9800998ecf8427e/en_GB-1988229788/4733/f235dd088df5682b0560ab6fc66ed22c9124c0be.3/7b3a13c140c13e9ca5f4681905edf481/_/download/contextbatch/css/editor,macro-browser,fullpage-editor,-atl.general/batch.css&quot; media=&quot;all&quot;&gt;
