No, you can count on webpages being different between each 
domain. There is no convention between using <TR> or <Tr> or 
<tr>. Even "<font face" can be "<FONT ecaf". No table on any 
webpage is like any other table on another domain's pages. And 
some domains like to add new "features" and delete others 
occasionally. Comments will be changed, so will "class" names. 
Some sites change the web address of the pictures on a page 
every 5 minutes (so people cannot link to them). Advertising is 
inserted or deleted in the html, and the domain of the adserver will 
be changed. Javascript or style sheets will be edited as authors 
find whatever they write won't work the same on all browsers. You 
may notice some html tags can include other html tags, on some 
pages, but some other site will use separate tags. It's a good idea 
to verify the page format you write code for hasn't changed 
periodically. Put in some code so that if the page's format has 
changed, or the data item in a table is not what you expect, it 
alerts you. Perhaps you search for "<!-- begin data -->", and 
someone changes that to "<!-- Data Goes Below -->". It's also a 
good idea to make sure your automatic "browser" doesn't register 
as a spammer or as a feeble denial of service attack by accessing 
the site too often.
