Python 元素不'；不存在于抛出超时异常的网站中，反之亦然

我正试图从这个特定网站的excel工作表中获取大量参考文件的DOI和URL“https://git.macropus.org/citation-finder/"我的问题是，有些引用没有DOI和URL，这意味着对于这些引用，包含与DOI和URL相关信息的web元素在网站中不存在，因此，在这种情况下，它应该进入NoTouchElementFoundException，但是它进入TimeoutException，这是我的代码，请帮助我更正代码

更清楚地说，正如您从参考woody的Image1中看到的，web元素引用数据存在，而参考woodybase的Image2没有web元素引用数据，因此，在这种情况下，它应该进入NosTouchElementFoundException，而不是进入TimeoutException，最初我有一个输入excel文件，它如下图所示，这就是excel输出的样子
