ImportXML查询给出内部错误

我刚刚写了我的第一个ImportXML函数来获取这样的产品。我想获取所有h3元素。但其显示import internal error。ImportXML查询给出内部错误

=ImportXML("https://www.google.com/products?q=ipod+nano","//h3")

我想这个查询还给予所有r类H3的元素，但它仍然显示了同样的错误？

=ImportXML("https://www.google.com/products?q=ipod+nano", 
       "//h3[@clsass='r')")

两个思路：1）首先尝试一个正常的HTTP地址，因为HTTPS通常需要特殊处理或设置的选项。 b）第二个XPath表达式包含两个错误。试试'// h3 [@ class ='r']'。 – 2014-10-20 09:36:39

是的，它的工作。谢谢@MarcusRickert – Diffy 2014-10-21 11:50:53

正如@MarcusRickert指出的那样，HTTPS页面可能是一个问题。使用他们的HTTP版本：

=IMPORTXML("http://www.google.com/search?tbm=shop&q=ipod+nano&gws_rd=ssl", "//h3")

结果（裁剪）：

Apple iPod Nano (6th Generation) - 8 GB - Graphite 
Apple iPod Nano (3rd Generation) - 4 GB - Silver 
Apple iPod Nano (4th Generation) - 8 GB - Pink 
Apple iPod Nano (PRODUCT) RED (7th Generation) - 16 GB - Red 
Apple iPod Nano (2nd Generation) - 4 GB - Silver 
Apple iPod Nano (5th Generation) - 8 GB - Black

Apple iPod Nano (7th Generation) - 16 GB - Space Gray 
Apple iPod Nano (5th Generation) - 16 GB - Black 
Apple iPod Nano (2nd Generation) - 4 GB - Green 
.....

这样做与你的第二个查询。再一次，信贷去马库斯发现在您的XPath表达式中的两个错误。试着更加小心地写出这些表达式！特别是clsass而不是class应该很容易捕捉到，如果你看看你的代码两次。

=IMPORTXML("http://www.google.com/search?tbm=shop&q=ipod+nano&gws_rd=ssl", "//h3[@class='r']")

结果：

感谢您给我的信贷！顺便提一下，这是Mar * c *我们。 SO的引擎不太聪明，无法纠正拼写。 :-) – 2014-10-21 06:01:28

@MarcusRickert我明白了，道歉 - K拼写在波恩更为常见！ – 2014-10-21 08:04:14

Http部分工作。另外我给了错误的URL，所以无法解析。 – Diffy 2014-10-21 11:52:20
