Rewrite the html tags for frontpage I am using views for front page. I was able to customize some things.

But I have some &lt;h1&gt;&lt;/h1&gt; in the body of an article and for the frontpage I want to change that automatically into &lt;h2&gt;&lt;/h2&gt;. Is that possible with views and if yes, how?
If you are having issue with the content that is being printed on the front page.
Then you can create a page--front.tpl.php and print the variable according to the requiremt.

If $title gives you the &lt;h1&gt; and &lt;h2&gt; tags, then you can strip_tags($title, 'tags that need to be maintained e.g. &lt;a&gt;') to remove the tags. 

If you have issues with views field label, you can use 'Rewrite the output of this field' and 'Strip HTML tags' to change the output mentioned in the image below:-



Hope it will help!
