ExtendScript: Get all text from a document

Question

Hi all.
I have the following task: I need to translate a document into another language using ExtendScript. So, as "input" I have a document with a text/graphics/tables/etc. in Language_1 and a "somehow-separated file", which will contain data about translation into the Language_2. E.g.:
Some_text_in_language_1     Some_text_in_language_2
Some_other_text_in_language_1     Some_other_text_in_language_2
To get the source text from the document, I've tried to use this:
var pgf = doc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;
while(pgf.ObjectValid()){
     var test = pgf.GetText(Constants.FTI_String);
     var text, str;
     text = "";
     for (var i=0; i < test.len ; i +=1)
          var str=test[i] .sdata.replace(/^\s+|\s+$/g, '') ; 
          text = text + str;
          PrintTextItem (test[i]);
     pgf = pgf.NextPgfInFlow;
But with this, I can only access the regular text in the document (e.g. the text in tables remains untougched). Is there any way I can the all textual data from specified document? Or maybe, the full list of controls, which can contain it, to iterate throught them and extract it one-by-one? Or maybe there's a better way to solve this problem?
Thanks in advance! Any advice would be greatly appreciated.

There is another way to loop through ALL paragraphs in a document, regardless whether they are in a table or in the main text flow. You can use the FirstPgfInDoc property of the document and loop through all Pgf objects using the NextPgfInDoc property of the Pgf until you reach an invalid object. Note that this also includes all paragraphs in the master and reference pages, so it might be useful to check where the Pgf is located (on a body page or not). There is a script on this forum that does that - I believe it was created and posted by Rick Quatro.
Working your way through the main text flow does not guarantee that you have all the visible text in the doc. There may be multiple flows and there may also be text frames that are placed inside anchored frames. Those text frames are not contained directly in the main flow of the document.
Good luck with your scripting
