ReplaceSingleLine doesn’t replace embedded tables

[Chris Reddick]

I have a document where I need to replace certain sections. The section are identified by a start tag and an end tag. Things work well unless there is a Table in one of the sections. All the text of the section is replaced but the Table structure remains. How can I get everything to be replaced? My code needs to be able to replace any kind of content between the start and end tag.

I start with this:

I expect to get this:

But I get this:

Here is my code:

WordDocument document = new WordDocument(Server.MapPath("Template.docx"), FormatType.Docx);document.ReplaceSingleLine(new Regex(@"\[TableStart\].*?\[TableEnd\]"), "");document.Save("Sample.docx", FormatType.Docx, HttpContext.Current.Response, HttpContentDisposition.Attachment);document.Close();

Docx Files attached.

Hi Chris, 

The ReplaceSingleLine API functionality is to replace a particular text that extended to several paragraphs in a document with another text. So it should not be replace the table in the document. It is the DocIO behavior. 

If you wish to replace certain sections (particular content such as paragraph, table) in the document, then we suggest you to use the bookmark functionality in DocIO to replace the particular content in the Word document. To meet you requirement, we suggest you insert the bookmark start and bookmark end( which denotes the range of the content) in the Word document. Using DocIO, you can replace the bookmark content from Word document using ReplaceBookmarkContent() API.

Please refer to the below code snippet. 

WordDocument document = new WordDocument(@"Template.docx", FormatType.Docx); 

 

String[] bookmarkNames = { "Table1","Table2","Table3"}; 

foreach (string bookmarkName in bookmarkNames) 

{ 

//Creates the bookmark navigator instance to access the bookmark 

BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(document); 

//Moves the virtual cursor to the location before the end of the bookmark 

bookmarkNavigator.MoveToBookmark(bookmarkName); 

//Create a empty text body part. 

TextBodyPart textBodyPart = new TextBodyPart(document); 

//Replaces the bookmark content with text body part 

bookmarkNavigator.ReplaceBookmarkContent(textBodyPart); 

} 

 

document.Save("Result.docx", FormatType.Docx); 

document.Close(); 

 
We have modified your input template document by inserting bookmark start and bookmark end to replace the content. Please refer to the modified document in below link.

Please refer to the below UG documentation to know how to work with bookmarks using DocIO.

Bookmarks are not very useful in my real-world use case because I need to be able to see and edit them in the document. Word does not make this easy to do. However, I do see the value of using them to accomplish removing the content between tags which includes tables. I will try to incorporate Bookmarks by automatically inserting them into the document where my tags are while I am processing the document.

Thanks
