I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

insertParagraph -- path and position
Thanks for the tolerance in putting up with these posts. I'm having difficulty with some of the basics of the modules.

I don't understand what is to be used for path and position. I've not found any examples in the documentation. Are there some that I have missed ? Could someone give me an example ?

If my template file contained a marker/token such as "INSERT PARAGRAPH HERE", how would I go about replacing that token with an arbitrary paragraph of text.

Thanks again for all your patience.

Bob

Can be given by [path, position] or by element reference. <br><br> Options are the same as for appendParagraph, with the additional option 'position' which determines whether the paragraph is inserted before or after the element at the given position. Possible values for this options are 'before' and 'after'. By default, the element is inserted before the given element.

Re: insertParagraph -- path and position

If you want to insert a paragraph, you have to indicate an existing element, so the new paragraph is inserted before or after the given element.

An existing element can be selected by an XPath expression followed by a zero-based absolute position number. For example ("//text:p", 2) is the third paragraph and ("//text:h", 0) is the first header. So, if you want to insert a new paragraph before the 3rd existing paragraph, you can write
$doc->insertParagraph("//text:p", 2, position => 'before');
The 'position' option can be set to 'before' or 'after'; here, the new paragraph becomes the third one. With 'after' it would become the fourth.

Alternatively, if you previously got the third paragraph container, knowing that XPath query calculations are more time-consuming than direct element access, you should use it instead of the "path + absolute position", as below:
my $p = $doc->getParagraph(2); $doc->insertParagraph($p, position => 'before');
