This is actually based on your suggestion (eons back..) -
toPlainTextString() is the uniform way of getting string representation of a
page - meaningful and hopefully semantic data. I think you'd probably want
to use toPlainTextString() instead of toString() - as toString() always
gives some output for all the tags, while toPlainTextString() works only for
specific ones like string nodes, link text and strings inside forms. It was
also enabled earlier for comments, but was taken out last week. I am
thinking of putting it back in. What this will mean is that if folks have
commented tags - you will get that sort of data in your string filter. I
think you can live with that (?)

Also - I am thinking of a better approach - wherein, should one require pure
strings within a comment, one could create a new parser, that operates on
the contents of the string node (it would be an interesting approach to
try..)

Regards,
Somik
