This isn't specifically about mobile programming but more about detecting mobile content so I would guess mobile gurus can advise on this....
Basically my VB.Net app is pulling down pages from servers using a webrequest. I parse these files to determine their content type etc.
I want to detect mobile content which is easy for the likes of :
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.2//EN"
"http://www.openmobilealliance.org/tech/DTD/xhtml-mobile12.dtd">
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.2//EN"
"http://www.wapforum.org/DTD/wml12.dtd">
<!DOCTYPE HTML PUBLIC "-//W3C//DTD Compact HTML 1.0 Draft//EN">
However looking at a few of the mobile frameworks (jquery to name one) they don't require any kind of signature. Having checked the content-type of a number of sites this also doesn't give anything away.
I could parse the script tags and assume that if there is a framework attached it is in use, but this seems like a pretty ropey assumption and requires me to know about all frameworks.
How would you propose that I detect if a page is a mobile one?
Should developers really be adding a DOCTYPE as good practice?

Writing your app was the hard part, but it’s not the last part. You still need to sell your app. Here's how to make sure your description puts your app in the best light. |
