Open XML : Retrieving Word Content Based on Styles

To find or retrive content style based conetent from created word document:

Follow this code:

public static string paraStyle = "Heading1";
public static string paraStyle2 = "Heading2";

using (WordprocessingDocument WorDocument = WordprocessingDocument.Create(@"c:\Test.docx", WordprocessingDocumentType.Document))
{
// Add a new main document part.
MainDocumentPart mainPart = WorDocument.AddMainDocumentPart();
//Create Document tree for simple document.
mainPart.Document = new Document();
//Create Body (this element contains other elements that we want to include
Body body = new Body();
mainPart.Document.Append(body);
// Save changes to the main document part.
mainPart.Document.Save();


int countHeading1= mainPart.ParagraphsByStyleName(paraStyle).Count();
int countHeading2 = mainPart.ParagraphsByStyleName(paraStyle2).Count();
}
}


//Content Serch code.
