It depends on what you want to do, however, if you are primarily interested in the text between the two tabs, then this is one of the cases when the semantics of XmlDocument / XPath are easier to use than LINQ to XML, a typed Open XML object model SDK V2. The semantics of the "next :: *" XPath axis are what you want. The following example uses XmlDocument and XPath to print node names between the beginning and end of a bookmark.
using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Xml; using DocumentFormat.OpenXml.Packaging; using DocumentFormat.OpenXml.Wordprocessing; class Program { public static XmlDocument GetXmlDocument(OpenXmlPart part) { XmlDocument xmlDoc = new XmlDocument(); using (Stream partStream = part.GetStream()) using (XmlReader partXmlReader = XmlReader.Create(partStream)) xmlDoc.Load(partXmlReader); return xmlDoc; } static void Main(string[] args) { using (WordprocessingDocument doc = WordprocessingDocument.Open("Test.docx", false)) { XmlDocument xmlDoc = GetXmlDocument(doc.MainDocumentPart); string wordNamespace = "http://schemas.openxmlformats.org/wordprocessingml/2006/main"; XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable); nsmgr.AddNamespace("w", wordNamespace); XmlElement bookmarkStart = (XmlElement)xmlDoc.SelectSingleNode("descendant::w:bookmarkStart[@w:id='0']", nsmgr); XmlNodeList nodesFollowing = bookmarkStart.SelectNodes("following::*", nsmgr); var nodesBetween = nodesFollowing .Cast<XmlNode>() .TakeWhile(n => { if (n.Name != "w:bookmarkEnd") return true; if (n.Attributes.Cast<XmlAttribute>().Any(a => a.Name == "w:id" && a.Value == "0")) return false; return true; }); foreach (XmlElement item in nodesBetween) { Console.WriteLine(item.Name); if (item.Name == "w:bookmarkStart" || item.Name == "w:bookmarkEnd") foreach (XmlAttribute att in item.Attributes) Console.WriteLine("{0}:{1}", att.Name, att.Value); } } } }
