Replace bookmark text in Word file using Open XML SDK

Question

I assume v2.0 is better... they have some nice \"how to:...\" examples but bookmarks don\'t seem to act as obviously as say a Table... a bookmark is defined by two

Answer 1

After a lot of hours, I have written this method:

    Public static void ReplaceBookmarkParagraphs(WordprocessingDocument doc, string bookmark, string text)
    {
        //Find all Paragraph with 'BookmarkStart' 
        var t = (from el in doc.MainDocumentPart.RootElement.Descendants()
                 where (el.Name == bookmark) &&
                 (el.NextSibling() != null)
                 select el).First();
        //Take ID value
        var val = t.Id.Value;
        //Find the next sibling 'text'
        OpenXmlElement next = t.NextSibling();
        //Set text value
        next.GetFirstChild().Text = text;

        //Delete all bookmarkEnd node, until the same ID
        deleteElement(next.GetFirstChild().Parent, next.GetFirstChild().NextSibling(), val, true);
    }

After that, I call:

Public static bool deleteElement(OpenXmlElement parentElement, OpenXmlElement elem, string id, bool seekParent)
{
    bool found = false;

    //Loop until I find BookmarkEnd or null element
    while (!found && elem != null && (!(elem is BookmarkEnd) || (((BookmarkEnd)elem).Id.Value != id)))
    {
        if (elem.ChildElements != null && elem.ChildElements.Count > 0)
        {
            found = deleteElement(elem, elem.FirstChild, id, false);
        }

        if (!found)
        {
            OpenXmlElement nextElem = elem.NextSibling();
            elem.Remove();
            elem = nextElem;
        }
    }

    if (!found)
    {
        if (elem == null)
        {
            if (!(parentElement is Body) && seekParent)
            {
                //Try to find bookmarkEnd in Sibling nodes
                found = deleteElement(parentElement.Parent, parentElement.NextSibling(), id, true);
            }
        }
        else
        {
            if (elem is BookmarkEnd && ((BookmarkEnd)elem).Id.Value == id)
            {
                found = true;
            }
        }
    }

    return found;
}

This code is working good if u have no empty Bookmarks. I hope it can help someone.
