Please edit your question to include your XML code you meant to share. Click on the gear icon to the right of your question's title and click Edit. After you paste your XML, highlight all of that code and, as @jkat54 says, click on the Code Sample button in the text editing tools. This will ensure your XML renders properly on this site.
Use the "code sample/blocks" button to put your xml code in blocks. Or use a site like pastebin.com if you still cant get the code to show up.
if you use the single leaning quote (below ~ tilda on my keyboard) it quotes the xml and html tags very well
