how to use XMLTextWriter to write XML node at a specified position

Question

I have an xml file likes below.

<?xml version="1.0" encoding="utf-8" ?>
<Book>
  <Title>Title</Title>
  <Content>Content</Content>
</Book>

I want to write a new node after 'Content', I know how to use XMLDocument to do that, is there a way to use XMLTextWriter to do that?

Answer 1

You will have to write the whole Xml document, i.e. all elements and attributes and attribute values by using the XmlTextWriter. After you've written the <Content> element, you can write your additional element.

Something like this:

writer.WriteStartDocument();
writer.WriteStartElement("Book");
writer.WriteStartElement("Title");
writer.WriteString("Title");
writer.WriteEndElement();
writer.WriteStartElement("Content");
writer.WriteString("Content");
writer.WriteEndElement();
// insert your new data here
writer.WriteEndElement();
writer.WriteEndDocument();
