Indexing (all): XPath and CSS use 1-based indexing; DOM and Selenium’s table syntax use 0-based indexing.
Prefixes (all): xpath= required unless expression starts with // ● dom= required unless expression starts with “document.” ● css= always required ● identifier= never required.
Cardinality (Selenium): XPath and CSS may specify a node set or a single node; DOM must specify a single node. When a node set is specified, Selenium returns just the first node.
Content (XPath): Generally should use normalize-space() when operating on display text.
General
Notes
 DOM has limited capability with a simple ‘document…’ expression; however, arbitrary JavaScript code may
be used as shown in this example.
 CSS does not support qualifying elements with the style attribute, as in div[style*='border-width'].
 Selenium uses a special syntax for returning attributes; normal XPath, CSS, and DOM syntax will fail.
 CSS: The CSS2 contains function is not in CSS3; however, Selenium supports the superset of CSS1, 2, and 3.
DOM: firstChild, lastChild, nextSibling, and previousSibling are problematic with mixed content; they will
point to empty text nodes rather than desired elements depending on whitespace in web page source.

Rosetta Stone and Cookbook
Sprinkled with Selenium usage tips, this is both a general-purpose set of recipes for each technology as well as
a cross-reference to map from one to another. The validation suite for this reference chart
(http://bit.ly/gTd5oc) provides example usage for each recipe supported by Selenium (the majority of them).
