HOWTO: Make Windows Live Writer Output XHTML Markup

Problem:

• The output you get from Windows Live Writer is not XHTML, i.e. unclosed br and img tags.

Possible causes:

• When you’ve setup your blog in Windows Live Writer, you have used a version older than Beta 3
• Your blog’s style couldn’t have been detected by WLW
• Your blog’s style was been detected correctly, however you do not have a valid XHTML DOCTYPE declaration in your blog

Setting XHTML output manually:

• Weblogs

  Edit Weblog Settings

  Advanced

  Markup Type

Thanks Mr. Joe Chang, from the Windows Live Writer team, who have pointed that out for me.
