Google spreadsheet importxml : how to grab all names of element nodes in XML

问题

I'm trying to use importxml function to import XML.

<item>
    <name>James</name>
    <date>11/11/2016</date>
    <description>Student</description>
</item>

If I use,

=importxml(URL, "//item")

I can import the information, but not the names of each information.

I'd like to pull something like this

name      date       description
James     11/11/2016 Student

Any xPath function to do this?

回答1:

You can get the headers with this formula:

=unique(arrayformula(regexreplace(transpose(split(IMPORTDATA(A1),"><",false)),">.*|\/","")))

Basically what I do, is use importdata to pull everything on the page, then using split and transpose functions, I force it to split based on each nested item >< , transpose is to swap it vertically.

At that point this is what you would see:

Then using regexreplace with arrayformula I remove all the data after the headers with ">.*|\/" and then use unique to give me a final unique list of all headers.
