Unlike wodHtmlParser.Parts
property that contains *all* entities found in the
document, Parts property will return collection of child
entities only. For example, when this HTML structure is
found:
<TABLE>
<TR>
<TD>text</TD>
</TR>
</TABLE>
there will be 3 entities in wodHtmlParser.Parts
collection: TABLE, TR and TD. However, TR entity will
contains one child entity: TD, and that entity will be
accessible also through wodHtmlEntity.Parts collection,
although TD entity is exactly the same object instance as
one accessed through main Parts collection.
