>>Do a Google search on "html to xhtml converter". One of the links is this handy online form:

>>>Is there any converter that'd rectify an HTML to be compatible for use as an XSL? All I need is the conversion of attributes. ie:In HTML attributes look like:
>>>

>>><table border=1 cellSpacing=0>
>>> <tr>
>>>  <td colspan=2></td>
>>> </tr>
>>>...
>>>

>>>and I'm after a converter that'd make it:
>>>

>>><table border="1" cellSpacing="0">
>>> <tr>
>>>  <td colspan="2"></td>
>>> </tr>
