I'm doing some attribute parsing as a string, so I need to know how spaces are used in HTML/XHTML element attributes:

  <div id='myid' width='150px' />

Is this also correct?

  <div id = 'myid' width = '150px' />

If anyone knows other ways of iterating through attributes and their values using JavaScript, I'd be interested to know.

  • You might want to specify what language you're trying to do the parsing in - if in C, C#, JavaScript. If JavaScript, are you perhaps trying to your own HTML document from within a browser, or offline? – Shalom Craimer Commented May 6, 2009 at 6:27
  • Note that the width attribute is (a) deprecated and (b) takes either an integer or percentage - don't specify px in HTML (but always specify units in CSS). The validator won't pick this up, because the DTD doesn't express this rule (and I don't think DTDs are capable of doing that either) – Quentin Commented May 6, 2009 at 8:35

Yes, both are correct. Rather than string parsing, you'll want to use the DOM. Check out jquery.

The spaces are allowed. If you are parsing attributes why don't you let the browser parse? If you are using innerHTML than you get elements that have an attribute list
