It seems that you should use ‘pdftron.PDF.TextSearch’ with a regular expression to match your fileds (i.e. [FOO] ) then use ‘pdftron.PDF.ContentReplacer’ to update fileds (i.e. replace placeholder names with values).
As a starting point, please see the corresponding sample projects:
TextSearch: http://www.pdftron.com/pdfnet/samplecode.html#TextSearch
ContentReplacer: http://www.pdftron.com/pdfnet/samplecode.html#ContentReplacer
The reg exp used to find variable text could be: [[A-z,0-9,-,_]++]. For example:
TextSearch.Mode mode = TextSearch.e_reg_expression | TextSearch::e_whole_word | TextSearch::e_ambient_string | TextSearch::e_highlight;
string pattern = “[[A-z,0-9,-,_]++]”;
txt_search.SetPattern(pattern);
…
text_search.Begin(mp_doc, pattern, mode, pg_num, pg_num);
…

Hi,
My first post here so bear with me.
I want to be able to return a list of fields in a PDF, by fields I mean a string of text that matches this pattern ‘[ANY WORDS]’ i.e a open bracket, some wording and a close bracket.
I then which to use this with content replacer etc. So the idea is my user can upload a pdf with some fields and I can build a form so they can update.
Any thoughts on how to do this?
Many thanks,
Brett
