I'm trying to parse HTML file with libxml2. Usually this works fine, but not in this case:

<p>
    <b>Titles</b>
    (Some Text)
    <table>
        <tr>
            <td valign="top">
                …Something1...
            </td>
            <td align="right" valign="top">
                …Something2...
            </td>
        </tr>
    </table>
</p>

I do this query to get the first <td>

//p[b='Titles']/table/tr/td[0]

but nothing is returned because libxml think that <table> tag is not a child of a tag <p> and following him.

And finally the question WHY?
