GetChildNodes - within certain sections or form fields only

I am using the code below to replace hyphens with nonbreaking hyphens to address some business rules required formatting.

//Replace hyphens with non breaking hyphens

NodeCollection runs = doc.GetChildNodes(NodeType.Run, true);

foreach (Run run in runs)


// only replace for endorsementids (which contain two spaces together and hyphens)

if (run.Text.Contains("-") && run.Text.Contains(" “))


run.Text = run.Text.Replace(”-", “” + ControlChar.NonBreakingHyphenChar);



The code works, but it iterates through the entire document. I know the only places that need to have the replacement done are always in the first two sections of the document. Also, the text is always within a form field.

Is there away to limit the code to run only with certain sections or only on text with a form field?

Hi Doug,

Document doc = new Document(MyDir + "in.docx");
