如何在ImportXML的URL中包含Google表格单元格引用

Question

I have this ImportXML formula :

=IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date=2018-04-01"; "//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']")

I want the value of the parameter "&date=" to be replaced by a cell reference (B1).

I've tried this :

=IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date="&B1"; "//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']")

But Google Sheet gave me an error. Any insights?

Answer 1

I think that when "https://www.x-rates.com/historical/?from=USD&amount=1&date="&B1 is used, 2018-04-01 of "B1" may be converted to the serial number. And please remove " of &B1"; . So how about these modifications? I think that there are several answers for your situation. So please think of this as one of them.

=IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date=" & TO_TEXT(B1) ; "//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']")

or

=IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date=" & TEXT(B1,"yyyy-MM-dd") ; "//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']")

References :

• TO_TEXT
• TEXT

If this was not what you want, I'm sorry.

Edit :

In your question, =IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date=2018-04-01"; "//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']") returns the same values like 1.232118 1.232118 . So this is not due to date=" & TO_TEXT(B1) ; . It is considered that this is due to the xpath. I couldn't notice that this is your another issue from your question. I'm really sorry. So I updated the xpath.

=IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date= & TO_TEXT(B1) , "//tr[1]//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']")

Note :

• There are 2 <td class='rtRates'><a href='http://www.x-rates.com/graph/?from=EUR&amp;to=USD'> in the URL. So 1st one is retrieved in this modification. When you want to 2nd one please use =IMPORTXML("https://www.x-rates.com/historical/?from=USD&amount=1&date= & TO_TEXT(B1) , "//tr[position()>1]//a[@href='http://www.x-rates.com/graph/?from=EUR&to=USD']")

If I couldn't notice something yet and I misunderstand your question, I'm sorry.
