While reading html files we encountered the problem that we end up with an empty list.

Here is a small example:

from unstructured.partition.html import partition_html
html_content="""
<!DOCTYPE html>
<html class="client-nojs" lang="de" dir="ltr">
<head>
</head>
<body>
  <div id="content" class="mw-body" role="main">
    <Seitenname>Bestellvorschläge weiterbearbeiten</Seitenname>
    <hr>
    <div class="content">
      <hauptteil_AB>
        <div class="rumpftabelle"></div>
        <table>
          <tbody>
            <tr>
              <th>Intern</th>
              <th>Feldwerte
              </th>
            </tr>
            <tr>
              <td>J</td>
              <td>Ja
              </td>
            </tr>
            <tr>
              <td>N</td>
              <td>Nein
              </td>
            </tr>
          </tbody>
        </table>
    </div>
    </hauptteil_AB>
    <fussteil_B></fussteil_B>
  </div>
  </div>
</body>
</html>
"""
elements = partition_html(text=html_content)
print(elements)
out[0]: []

We would expect something like

out[0]: [<unstructured.documents.elements.Title object>, <unstructured.documents.elements.Table object>]

We use version 0.15.13 of unstructured.

Through try and error, the problem seems to come from the custom tags <hauptteil_AB> and <fussteil_B>.
We appreciate any help on this issue.

Same problem.

I guess the cause is here:

unstructured/unstructured/partition/html/parser.py

Line 841 in ca27b8a

return True

It seems this is a feature, but it makes the HTML parser unable to parse custom HTML tags appropriately.
