Reverse Engineer XPath of WebElement
Question
I was wondering if it's possible to reverse engineer the XPath of a WebElement if one of the attributes are known but the path is unknown. For example, suppose the XPath to a certain WebElement is (@id,'vi_main_img_fs_thImg')]/img but this is not known. I know however that this WebElement will return http://myimage.com/72hjf89 (ie, a unique value) when calling WebElement.getAttribute("src") - is it possible to use the information to "reverse engineer" the original XPath value? Perhaps using Regex or something?
Note: The .getAttribute("src") was only an example, I suppose whatever method works will work no matter what attribute is used as long as this value occurs once on page.
Any ideas?
Update:
To give more detailed example of what I'm trying to achieve I'm copying HTML code below.
The page I am looking at is: http://www.ebay.com/itm/111488868372
The HTML on page is:
<document>

<!-- </span> -->
</div>
</a>
The "src" value is: http://i.ebayimg.com/images/g/eHAAAOSwLzdWS4C8/s-l300.jpg (this is the only known value)
The value (ID) I am trying to obtain with this method is:
.//*[@id='PicturePanel']/div[1]/div[1]/table/tbody/tr/td/a/div/img[2] (this is the XPath to element)

You can just use a different XPATH.
The id will (usually) be unique, so it makes more sense to look for an element using the id attribute.
UPDATE: You can retrieve the ID by using an XPATH that looks like this:
//img[@src = "http://i.ebayimg.com/images/g/eHAAAOSwLzdWS4C8/s-l300.jpg"]/string(@id)
In case the result has more than one elements, you will get a sequence.
