需要获取iframe内跨度的xpath表达式。
在获取IPath弹出窗口中跨度的XPath表达式时需要帮助。
我可以获取iframe，但在iframe中获取/html/body不会发生任何帮助，我们将不胜感激
<div class="gwt-PopupPanelGlass" style="position: absolute; left: 0px; top: 0px; visibility: visible; display: block; width: 1680px; height: 222px;"></div>
<div class="gwt-PopupPanel" style="left: 439px; top: 0px; visibility: visible; position: absolute; overflow: visible;">
<div class="popupContent">
<div class="ph-PopupDialog" style="position: relative; width: 800px; height: 220px;">

最佳答案
使用:
//iframe//span
这将选择XML文档中任何
span元素的后代的每个iframe元素。关于javascript - 需要帮助以获取XPath表达式以在iframe弹出窗口中生成跨度，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/7923718/
