I need to override this data record from blog module:

<record id="menu_news" model="website.menu">            
  <field name="name">Blog</field>            
  <field name="url" eval="'/blog/'+str(ref('website_blog.blog_blog_1'))"/>            
  <field name="parent_id" ref="website.main_menu"/>            
  <field name="sequence" type="int">40</field>            
  <field name="website_id" ref="website.default_website"/>        
</record>

Then I will change the URL. How can I inherit that in my module?
