Blogger Template Issue

Today I tried to understand Blogger's template and then to reorganize my template for my blog. As I understand that the template is a html-like file. I can update this file so that I can add other elements such as RRS link I did previous.

Based on xml and html knowledge I have, I tried to change me template. Here is an example tags for blog title before my change:

<BlogItemUrl><a href="<$BlogItemUrl$>"
  title="external link"></BlogItemUrl>

  <$BlogItemTitle$>

<BlogItemUrl></a></BlogItemUrl>

These tags are not looks in right logic. Then I tried to change them as:

<BlogItemUrl><a href="<$BlogItemUrl$>"
  title="external link">

  <$BlogItemTitle$>

  </a>
</BlogItemUrl>

I thought the updated one is better. However, after I saved the new template, I lost my blog title! I had to change these codes back. Fortunately, I saved my template before I did the change. As Blogger suggested, Always back up your template before you make any changes!
