I am working with a lot of DOM manipulation and need to know several values of an element to determine its position within the DOM and I have written the following to help scrape several of the bits of information I need to proceed.

To me this looks very heavy and there might be some room to help improve the speed / accuracy of returning this information.

Any help in speeding this up or helping with the redundancy issues would be most helpful.
