XMLWriter for HTML creation - how to add simple non-pair tags?

Question

Hi, I was advised to use XMLwriter to build HTML documents in order to display them in webbrowser object. Creating doctype and startelements like HTML,BODY is OK..but I am experiencing 2 main problems:

1. I cannot add tags like <br>. Using WriteString skips < and >.
2. The output string is one line - I would need something like writeLine. You know, when I display source its all in the first line.

Thanks

Answer 1

HTML is not a valid XML format, as you are discoving with tags like <img ...>

You could create XHTML, which is XML compliant (specify this in your DOCTYPE)

In XHTML single tags are writen like this <br /> for example

 HTML: <img src="..">
 XHTML: <img src=".." />

Whitespace layout is nice for humans to read, but makes no difference to how the browser renders the Xhtml. In fact stripping unnecessary whitespace will produce slightly smaller files.

Answer 2

You could use the Indent property:

var settings = new XmlWriterSettings();
settings.Indent = true;
using (var writer = XmlWriter.Create(outputStream, settings))
{
    writer.WriteDocType("html", "-//W3C//DTD XHTML 1.0 Transitional//EN", "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd", null);
    writer.WriteStartElement("html");
    writer.WriteStartElement("body");
    writer.WriteStartElement("b");
    writer.WriteValue("Test");

    writer.WriteEndElement();
    writer.WriteEndElement();
    writer.WriteEndElement();
}
