当我在以下文件上运行xmlstarlet sel -t -v '//i[@class = "iconSucc"]/@class'时，出现以下错误消息。有人知道如何解决该问题吗？

Answer 1

您的HTML文件不是格式正确。第77行的<img>元素

<img style="height: 24px; border: 0px none; vertical-align: middle;" src="/Content/images/gongshangbiaoshi.gif" alt="" class="footpic" >

未关闭。添加结束标记... />以使其格式正确：

<img style="height: 24px; border: 0px none; vertical-align: middle;" src="/Content/images/gongshangbiaoshi.gif" alt="" class="footpic" />

然后输出将是：

iconSucc
