    }
    WebElement parentElement = childElement.findElement(By.xpath("..")); 
    List<WebElement> childrenElements = parentElement.findElements(By.xpath("*"));
    int count = 0;
    for(int i=0;i<childrenElements.size(); i++) {
        WebElement childrenElement = childrenElements.get(i);
        String childrenElementTag = childrenElement.getTagName();
        if(childTag.equals(childrenElementTag)) {
            count++;
        }
        if(childElement.equals(childrenElement)) {
            return generateXPATH(parentElement, "/" + childTag + "[" + count + "]"+current);
