Using if then else and expression

Given this code:

      <b:if cond='data:blog.pageType == &quot;item&quot;'>
        <h3 class='post-title entry-title *itempage'* itemprop='name'>
          <b:if cond='data:post.link or (data:post.url and data:blog.url != 
data:post.url)'>
            <a expr:href='data:post.link ? data:post.link : 
data:post.url'><data:post.title/></a>
          <b:else/>
            <data:post.title/>
          </b:if>
        </h3>
      <b:else/>
        <h3 class='post-title entry-title' itemprop='name'>
          <b:if cond='data:post.link or (data:post.url and data:blog.url != 
data:post.url)'>
            <a expr:href='data:post.link ? data:post.link : 
data:post.url'><data:post.title/></a>
          <b:else/>
            <data:post.title/>
          </b:if>
        </h3>
            </b:if> 

Is there a specialist who can do this in a shorter way like in this pseudo 
code?

        <h3 <b:if cond='data:blog.pageType == &quot;item&quot;'> THEN set 
class="post-title entry-title *itempage*" ELSE set class"post-title 
entry-title"' itemprop='name'>
          <b:if cond='data:post.link or (data:post.url and data:blog.url != 
data:post.url)'>
            <a expr:href='data:post.link ? data:post.link : 
data:post.url'><data:post.title/></a>
          <b:else/>
            <data:post.title/>
          </b:if>
        </h3>
