想要检索给定WebElement的Xpath [英] Want to Retrieve Xpath of Given WebElement

问题描述

使用Selenium WebDriver，我可以在页面中找到所有Web元素的列表.我想编写一个函数，该函数将向我返回所传递元素的XPath字符串.

Using Selenium WebDriver, I am having a list of all web elements in the page. I want to write one function which will return me the XPath string of passed element.

函数调用将类似于:- String XpathOfElement = myWebDriver.getXpath(My_Web_Element)

Call for Function will be like:- String XpathOfElement = myWebDriver.getXpath(My_Web_Element)

提示:-我认为我们可以使用javascript(使用JavaScriptExecuter).但是不熟悉javascript.

Hint :- I think we can use javascript(using JavaScriptExecuter). But not familiar with javascript.

推荐答案

选中此 post ，我编写了获取绝对XPath的代码.

Check this post, I wrote code to get an absolute XPath.

public static String getAbsoluteXPath(WebElement element)
{
    return (String) ((JavascriptExecutor) driver).executeScript(
            "function absoluteXPath(element) {"+
                    "var comp, comps = [];"+
                    "var parent = null;"+
                    "var xpath = '';"+
                    "var getPos = function(element) {"+
                    "var position = 1, curNode;"+
                    "if (element.nodeType == Node.ATTRIBUTE_NODE) {"+
                    "return null;"+
                    "}"+
                    "for (curNode = element.previousSibling; curNode; curNode = curNode.previousSibling) {"+
                    "if (curNode.nodeName == element.nodeName) {"+
                    "++position;"+
                    "}"+
                    "}"+
                    "return position;"+
                    "};"+

                    "if (element instanceof Document) {"+
                    "return '/';"+
                    "}"+

                    "for (; element && !(element instanceof Document); element = element.nodeType == Node.ATTRIBUTE_NODE ? element.ownerElement : element.parentNode) {"+
                    "comp = comps[comps.length] = {};"+
                    "switch (element.nodeType) {"+
                    "case Node.TEXT_NODE:"+
                    "comp.name = 'text()';"+
                    "break;"+
                    "case Node.ATTRIBUTE_NODE:"+
                    "comp.name = '@' + element.nodeName;"+
                    "break;"+
                    "case Node.PROCESSING_INSTRUCTION_NODE:"+
                    "comp.name = 'processing-instruction()';"+
                    "break;"+
                    "case Node.COMMENT_NODE:"+
                    "comp.name = 'comment()';"+
                    "break;"+
                    "case Node.ELEMENT_NODE:"+
                    "comp.name = element.nodeName;"+
                    "break;"+
                    "}"+
                    "comp.position = getPos(element);"+
                    "}"+

                    "for (var i = comps.length - 1; i >= 0; i--) {"+
                    "comp = comps[i];"+
                    "xpath += '/' + comp.name.toLowerCase();"+
                    "if (comp.position !== null) {"+
                    "xpath += '[' + comp.position + ']';"+
                    "}"+
                    "}"+

                    "return xpath;"+

                    "} return absoluteXPath(arguments[0]);", element);
}
