Examples

Shows how to select certain nodes by using an XPath expression.

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

// This expression will extract all paragraph nodes,
// which are descendants of any table node in the document.
NodeList nodeList = doc.SelectNodes("//Table//Paragraph");

// Iterate through the list with an enumerator and print the contents of every paragraph in each cell of the table.
int index = 0;

using (IEnumerator<Node> e = nodeList.GetEnumerator())
    while (e.MoveNext())
        Console.WriteLine($"Table paragraph index {index++}, contents: \"{e.Current.GetText().Trim()}\"");

// This expression will select any paragraphs that are direct children of any Body node in the document.
nodeList = doc.SelectNodes("//Body/Paragraph");

// We can treat the list as an array.
Assert.AreEqual(4, nodeList.ToArray().Length);

// Use SelectSingleNode to select the first result of the same expression as above.
Node node = doc.SelectSingleNode("//Body/Paragraph");

Assert.AreEqual(typeof(Paragraph), node.GetType());
