XML : How to show a text in only search pages on Blogger?

I'm having a problem about showing headdings. I have added search box into my blog, but in homepage there is a text called "Latest News". It is in just homepage and archive pages. But when I search something in my search box, there is still this headding.

I use this code:

  <b:if cond='data:blog.url == data:blog.homepageUrl'>  <h5>Latest News</h5>  </b:if>    

What can I do to change this text in only search pages.
