looking for code like this

<!-- navigation --> <b:include name='nextprev'/>






and replace with code

<!-- navigation -->
<b:if cond='data:blog.pageType == &quot;index&quot;'>
<b:include name='nextprev'/>
<b:else/>
<b:if cond='data:blog.pageType == &quot;archive&quot;'>
<b:include name='nextprev'/>
<b:else/>
<b:if cond='data:blog.homepageUrl != data:blog.url'>
<!-- navigation -->
<b:include name='nextprev'/>
