Vba Selenium:检查源代码中是否存在html标记 [英] Vba Selenium: Check if html tag is present in the source code

问题描述

这是我的问题，我有一个使用硒的Vba代码，该代码循环了很多网址.我需要验证是否存在一个标签，如果需要的话，我接下来需要继续执行代码，问题是我刚刚开始使用硒，并且我不知道如何验证给定标签是否存在.源代码.

This is my issue, I have a Vba code using selenium that loops trough a lot of urls. I need to validate if one tag is present, and if it is I need the code to resume next, the problems is that I just started to use selenium, and I don't know how to validate if the tag is present in a given source code.

这是标签:

<a class="fontdn" id="fontdn" href="#" title="Zoom Out (Key: -)">Zoom Out (Key: -)</a>

这是我到目前为止拥有的Vba-Selenium代码，它假定返回具有此id的元素数量，但是不起作用.

and this is the Vba-selenium code I have so far, this suppose to return the number of elements with this id but doesn't work.

If IE.findElementsByTitle("Zoom Out (Key: -)").Size() > 0 Then Exit For

推荐答案

我检查了Excel VBA的包装，但在代码中没有看到findElementsByTitle:

I checked the wrapper for Excel VBA, I don't see a findElementsByTitle in the code: https://code.google.com/p/selenium-vba/source/browse/trunk/wrapper/WebElement.cs

您应该可以使用:

If IE.findElementsByClassName("fontdn").Size() > 0 Then Exit For

修改

我仔细查看了包装器源，findElementsByClassName返回了一个数组.据我所知，Excel VBA阵列使用Length而不是Size().

I looked through the wrapper source some more, findElementsByClassName returns an array. Excel VBA array uses Length, not Size(), from what I can tell.

也许是吗?

If IE.findElementsByClassName("fontdn").Length > 0 Then Exit For
