odf.element.Node.__str__ includes annotation text in the node contents.

[detrout]

Hello,

I had a odt spreadsheet downloaded from google docs where the user had included some comments on some of the cells.

I extracted one of the cells that I was having problems iwth and replaced some of the text strings to be less internal project specific.

Given a cell like this:

<table:table-cell xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0" xmlns:text="urn:oasis:names:tc:opendocument:xmlns:text:1.0" xmlns:config="urn:oasis:names:tc:opendocument:xmlns:config:1.0" xmlns:ooo="http://openoffice.org/2004/office" xmlns:meta="urn:oasis:names:tc:opendocument:xmlns:meta:1.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:style="urn:oasis:names:tc:opendocument:xmlns:style:1.0" xmlns:fo="urn:oasis:names:tc:opendocument:xmlns:xsl-fo-compatible:1.0" xmlns:table="urn:oasis:names:tc:opendocument:xmlns:table:1.0" xmlns:number="urn:oasis:names:tc:opendocument:xmlns:datastyle:1.0" xmlns:loext="urn:org:documentfoundation:names:experimental:office:xmlns:loext:1.0" xmlns:css3t="http://www.w3.org/TR/css3-text/" xmlns:draw="urn:oasis:names:tc:opendocument:xmlns:drawing:1.0" xmlns:svg="urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0" xmlns:of="urn:oasis:names:tc:opendocument:xmlns:of:1.2" xmlns:form="urn:oasis:names:tc:opendocument:xmlns:form:1.0" xmlns:ns42="urn:org:documentfoundation:names:experimental:calc:xmlns:calcext:1.0" xmlns:xlink="http://www.w3.org/1999/xlink" table:style-name="ce1969" office:value-type="string" ns42:value-type="string">
  <office:annotation draw:style-name="gr3" draw:text-style-name="P2" svg:width="95.57mm" svg:height="15.08mm" svg:x="38.52mm" svg:y="1388.3mm" draw:caption-point-x="-4.07mm" draw:caption-point-y="-8.1mm">
    <dc:date>2025-05-12T00:00:00</dc:date>
    <text:p text:style-name="P1">
      <text:span text:style-name="T1">On Day2, did thing.</text:span>
    </text:p>
    <text:p text:style-name="P1">
      <text:span text:style-name="T1">
        <text:tab/>
      </text:span>
      <text:span text:style-name="T1">-Commenter</text:span>
    </text:p>
  </office:annotation>
<text:p>Cell Value</text:p></table:table-cell>

str() was returning text like "2025-05-12T00:00:00OnDay2, did thing.-CommenterCell Value"

I'd really like a way to get just the cell contents and ignore the comment. Ideally there'd be separate functions for accessing the annotation and cell value.
