I just made a plugin called Validation Helper. This plugin converts XHTML output to HTML and will allow you to check all your posts and pages against the W3C Validator. Download
I face a problem when I am going to install feed burner. A feed validator message is shown which is given in the below- This feed does not validate. * line 80, column 0: XML parsing error: <unknown>:80:0: junk after document element [help] <div style="text-align: center;"><div style="position:relative; top:0; margi ... In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendation. * line 35, column 0: style attribute contains potentially dangerous content: ;border: #CCCCCC solid 1px (3 occurrences) [help] <description><![CDATA[<div class='hpt_container' style='width:100%;display ... Now my question is- can this plugin solve the problem? If not how can I solve it. Plz help me.
I just fixed a lot of bugs and added a contact form for bug reports. The version 1.5 will appear in your WP soon. I am sorry, this plugin is designed for template validation only.
