DocumentTextSearch bug?

[Roy]

Hi,
I am not sure if I am losing it or there is actually a bug with DocumentTextSearch. I have a document for which I want to find a replace some text. all the text that needs to be replace matches this regular expression {{(.*?)}}. Now the code below works for everything except if the text has a number in it. For example, say I want to match {{COM_LDL}}, then this gets matched perfectly. but if i want to match {{COM_LDL1}} then only {{COM_LDL is matched and the rest is disregarded. Below is the code, can somebody please help?
Thanks,
Roy

 DocumentTextSearch search = new DocumentTextSearch(rtb.Document);
                List<TextRange> rangesTrackingDocumentChanges = new List<TextRange>();
                foreach (var textRange in search.FindAll("{{(.*?)}}")) //find all merge fields
                {
                    TextRange newRange = new TextRange(new DocumentPosition(textRange.StartPosition, true), new DocumentPosition(textRange.EndPosition, true));
                    
                    rangesTrackingDocumentChanges.Add(newRange); --> this is where the problem happens.  if there is a number (COM_LDL1) then newRange.StartPosition.ToString() returns "\"{{COM_LDL\"@0" if there isnt a number then newRange.StartPosition.ToString() works perfectly and returns "\"{{COM_LDL}}\"@0"

                }

Hi Roy,

Thank you for contacting us!

The given regular expression {{(.*?)}} finds correctly all wanted matches in the document. There is no exception, even if the text has a number in it. Please take a look at the attached demo project.

Probably you are misled by the functionality of the ToString() method, which works perfectly right in the context of the current layout box. To further explain, the match in the document - {{COM_LDL1}} consists of three layout boxes, the first of which holds the {{COM_LDL text and DocumentPosition’s ToString() method returns the position in the current layout box.

I hope this helps! Let me know if you have other comments or questions.

Hi Yancho,
Thank you very much, you were right, I was misguided by what the "ToString()" function did in this context. I was able to solve the issue using your example.
Cheers,
Roy
