How to parse html embedded in xml in R?

Question

I have one input file which has html tag embedded in xml for example

 <Root>
   <Section1>
   <p>some text</p>
   <br>
   <table>
       <th></th>
       <tr>
       <td></td> 
       </tr>    
   </table>
   </Section1>
  <Section2>
  <ol>
      <li>1</li>
      <li>2</li>
      <li>3</li>
  </ol>
  </Section2>
</Root>

Is there any way to parse html embedded in xml document in R?

Actually, your question is a bit vague. This isn't an xhtml document. It looks like a snippet of XML, some of the tags which happen to be HTML tags. And with errors (<br> with no </br> or <br/>). So, what is it precisely you want to do?> — Spacedman

If its XHTML then it should be XML, so you use the standard XML parsers. You can find plenty about those elsewhere.

Note your <Section1> tag doesn't close properly. If this is a file you've pasted in, then there's a problem with it.

For XML, i m using package xml in R. I am successful in parsing it but how to parse html.

Steve Atkinson Over a year ago

what do you mean by parse exactly? if you say you are sucessful in parsing it, you should be be able to pick out the html tags using your parsed object... what EXACTLY are you trying to do?

I need to use parse the html data and reformat it into latex format.

So you want to turn <table> tags into LaTeX tabular environments, <li> into LaTeX itemize etc? In a completely general way? Give up. If your HTML is a tightly controlled subset of all HTML then it might be, but you will need to tell us exactly what that subset is. And you need to do some research.
