A few additions, since <paragraph><commentRangeStart id="commentId"
/><run><text>John</text></run><commentRangeStop id="commentId"
/></paragraph> is the critical thing:
<!-- comment range, text run "John" -->
<w:commentRangeStart w:id="0"/>
<w:r w:rsidDel="00000000" w:rsidR="00000000" w:rsidRPr="00000000">
<w:rPr><w:rtl w:val="0"/></w:rPr>
<w:t xml:space="preserve">John</w:t>
</w:r>
<w:commentRangeEnd w:id="0"/>
<xsd:element name="commentRangeStart" type="CT_MarkupRange">
<xsd:annotation>
<xsd:documentation>Comment Anchor Range Start</xsd:documentation>
</xsd:annotation>
</xsd:element>
<xsd:element name="commentRangeEnd" type="CT_MarkupRange">
<xsd:annotation>
<xsd:documentation>Comment Anchor Range End</xsd:documentation>
</xsd:annotation>
</xsd:element>
So if performance isn't a concern here (you don't need to save
pointers to where the comment ranges are), the pseudo-code for a
XWPFComment method that gets the text that a comment refers to would
be:
public String getRefersToText() {
StringBuilder refersTo = new StringBuilder();
for each CTParagraph in document:
for each child element of the CTParagraph:
if child element is a commentRangeStart and id==this.id
append subsequent text runs to the refersTo buffer
continue
if we have found the comment range start and child
element is a text run
append this text run to the refersTo buffer
if child element is a commentRangeEnd and id==this.id
return refersTo.toString() (assuming that one
comment may not refer to multiple text ranges)
}
This would require searching the entire document for every comment.
