Question

我刚刚编写了第一个ImportXML函数来获取这样的产品。我想获取所有h3个元素。但它显示import internal error。

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

我也试过这个查询来给所有h3元素添加类r，但它仍然显示相同的错误？

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

Answer 1

正如@MarcusRickert所指出的，HTTPS页面可能存在问题。使用它们的HTTP版本：

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

结果是（剪辑）：

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 (4th Generation) - 8 GB - Silver
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
.....

对第二个查询执行相同操作。再次，Marcus会在您的XPath表达式中发现两个错误。写这些表达时要小心点！如果您对代码进行两次查看，则clsass而不是class应该很容易捕获。

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

结果：

Apple iPod Nano (7th Generation) - 16 GB - Slate
Apple iPod Nano (6th Generation) - 8 GB - Graphite
Apple iPod Nano (3rd Generation) - 4 GB - Silver
Apple iPod Nano (4th Generation) - 8 GB - Pink
