Question

当我使用

时

'page-break-always: always'

表中的

样式。解析器抛出以下异常：

}

}

我也试过将样式添加到div元素中。它似乎不起作用。它会抛出相同的错误。

只有当作者有“OnEndPage”时才会抛出异常。与之相关的事件。如果删除事件，它可以正常工作，但需要在页面中添加页脚。

我做错了什么吗？有没有更好的方法可以强制div进入新页面？

更新

我已经意识到只有当我尝试在事件监听器中解析html页脚时才会发生这种情况。

我这样做：

footer=XMLWorkerHelper.ParseToElementList(footerHTML.Replace("pageNum", document.PageNumber.ToString()).Replace("updateDate", date), footerCss);

一旦它回到解析方法，它就会失败抛出上述错误。
