Please provide examples of what you've already tried, rather than asking for a solution straight out the door. — Jonathan, Apr 02 '17 at 05:25
i have tried this `substring-before(substring-after((//div/div[@class="ColorPicker"]/a/@style, "background-color: "), ";")')` — itsmnthn, Apr 02 '17 at 05:30
XPath is working but there is no results if i use `substring-before(substring-after((XPath/@style, "background-color: "), ";")')` with xpath — itsmnthn, Apr 02 '17 at 05:37
How did you execute that XPath? What was the function you used? — har07, Apr 02 '17 at 05:44
I execute XPath in chrome and this functions are i found in this site in another question — itsmnthn, Apr 02 '17 at 05:55
I have tried this `$e.outerHTML.substring($e.outerHTMLsubstring(';vertical',76).lastIndexOf(" ") + 1)` in PHP and in this $e is contain xpath result for `` this means `$e.outerHTML` contains the value or it is the variable — itsmnthn, Apr 02 '17 at 05:56
The XPath in your first comment should work if you run it using `DOMXPath::evaluate()` : [XPath Substring-After Help / Query/Evaluate?](http://stackoverflow.com/questions/30450323/xpath-substring-after-help-query-evaluate/30476787#30476787) — har07, Apr 02 '17 at 06:01
