Answer 1

In general DOM: For getting element by text in DOM

//*[text()='anytext']

or

Answer 2

Will 'contains' selector from jquery solve the problem?

Answer 3

If you have a modern browser, you can always use XPATH, since it has content-based search.

This is an example:

document.evaluate('//*[text()="' + string + '"]', document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE).snapshotItem(0);

And with older browsers, you can shim XPATH in with something like http://llamalab.com/js/xpath/
