如何找到图像元素的xpath

2024-05-13 • 问答

我有一个下面的HTML代码，该代码指向屏幕上的SVG（图像）元素

<div _ngcontent-c25="" class="chart-div ng-star-inserted">
      <!---->
      <!----><div _ngcontent-c25="" class="pie-div ng-star-inserted" d3-pie="">
				<svg width="80" height="80">
					<g transform="translate(40,40)" width="80" height="80"><g transform="translate(40,40)"></g>

					</g>
				</svg>
			<div class="attrFilter-tooltip" id="attributeFilterTooltipCountry" style="display: none; position: fixed; left: 1567px; top: 325px; z-index: 1000; background: rgb(238,238,238); box-shadow: rgb(153,153,153) 0px 0px 5px; color: rgb(51,51,51); width: 100px; text-align: center;"><div class="attrLabel" style="font-weight: bold;">Germany</div><div class="attrCount">693</div><div class="attrPercent">51.4%</div></div></div>

      </p>
      <!---->

    </div>

我能够找到直到div标签的元素，但是如果我尝试在SVG中访问该元素，并且其子镶边无法找到该元素

XPath：// div [@ class ='pie-div ng-star-inserted']-直到div 但是，如果我尝试访问其子元素SVG和路径，则根本找不到它（尽管代码在屏幕上可见）

我尝试过的Xpath：// div [@ class ='pie-div ng-star-inserted'] / svg / g / path 1

在屏幕上，该元素将如下图所示。

该元素实际上是屏幕上的svg图像（饼图），我们将其悬停在该元素上会显示相应位置数据的弹出窗口

您的xpath必须为//div[@class='pie-div ng-star-inserted']/*[name()='svg']/*[name()='g']/*[name()='path']-通过搜索xpath + svg来找到

还有另一种语法//div[@class='pie-div ng-star-inserted']/svg:svg/svg:g/svg:path-使用NSresolver参数，可以使其工作如下

const xpath = "//div[@class='pie-div ng-star-inserted']/svg:svg/svg:g/svg:path";
let result = document.evaluate(
  xpath,document,prefix => prefix === 'svg' ? 'http://www.w3.org/2000/svg' : null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null
);

for (var i = 0; i < result.snapshotLength; i++) {
  console.log(result.snapshotItem(i).getAttribute('fill'));
}
