Question

嘿，我有一个非常糟糕的标签元素，我需要从中获取文本。它被我不想要的其他元素所包围。

我可以轻松地定位我想要的元素的兄弟。

我如何定位＆＃34; Next Sibling＆＃34;的？

dlg4.window（标题=＆＃39; WindowTitleThing＆＃39;，CLASS_NAME =＆＃39;文本＆＃39）。draw_outline（）

我可以针对第一个孩子？

使用UIA后端。谢谢！

找到了这个，但无法让它发挥作用：

# Monkey patch for pywinauto that adds a first_only parameter to the window function 
# for the UIA backend, in order to work around slow FindAll calls (win10 bug?)
# First copy paste this code on your REPL, then do:
# d1 = pywinauto.Desktop("uia")
# d1.window(first_only=True, title="Calculator").window_text()
# Currently only title is supported, but its easy to implement all the others as well,
# most importantly title_re
