selecting all the columns in a table based on the column headersvalue

[yawnmoth]

<table>
<thead>
<tr>
<td>Part #</td>
<td>Description</td.
<td>Price</td>
</tr>
</thead>
<tr>
<td>...</td>
<td>...</td>
<td>...</td>
</tr>
</table>

Would it be possible to, using a single query, load every x'th <td> in
every <tr> after <thead> based on the position of the 'Price' <td> in
<thead>?

/table/tr/td[position() = count(../../thead/tr[1]/td[. =
'Price']/preceding-sibling::td) + 1]
