Choices, xpath, & [Brackets]

Posted on by russrimm Microsoft Employee

Hi all, I'm using xpath(xml(json(concat('{"root":{"choices":', item()?['MyValue'] , '}}'))), '/root/choices/Value/text()') to return an array from my Sharepoint list for each Choices column type and adding it to an HTML table.

When the values appear for each of the Choices columns, they appear in the HTML table as ["Value1","Value2"] but I want them to appear as Value1, Value2.

I've been trying to use replace unsuccessfully, so far, to strip out the brackets and quotes around each of the values so only the value itself is returned. ?

Thanks in advance!

Hi @russrimm

If you are getting results as ["Value1","Value2"] you can assign it to an array variable to get each value as you expected.

Now being said that i am not sure if this is your issue, if not please share a screen capture and a bit more details of your flow.

Thanks Deepak, I can get them into an array, I guess what i'm not sure if is once I get them into the array how to get them into my html table without the [""] around the values. I can't initialize an array variable in an Apply to Each, so it seems like ultimately I need to somehow initialize the array and join the values with a comma and then insert that into each row in my html table just to get rid of the [""]. When I try to initiailze the array it automatically adds an apply to each and then I get an error letting me know I can't initialize an array in an apply to each. My first step is a "Get sharepoint items" and then 3 of the columns are a "Choices" type and may have more than one value. Those are the ones i'm trying to strip the brackets and quotes from when they're added to my html table.

Hi @russrimm ,

Please try to use Join to remove brackets and quotes, since that it is an array.

Hope this helps.

Best Regards,

If I try doing an initialize variable of the Array type, as soon as I add my "Choices" column, it automatically adds an Apply to Each step and then tells me that I can't have an initialize array as the first step in an Apply to Each. I just want all the choices they selected (the choices columns allow multiple selection) to show in the CSV and HTML tables without the [" "] around them, otherwise it's working OK as it is. It just gets the items and adds them all to a csv and html, but the Choices columns are always adding the [" "].

Hi @Exon02 I ended up changing the column type to text and using comma delimited values with Split. I've learned to avoid using Choice column types more.

@russrimm @Exon02
Add join to your xpath to set your delimiter at the end of the expression.

join(xpath(xml(json(concat('{"root":{"choices":', item()?['MyValue'] , '}}'))), '/root/choices/Value/text()'), ', ')

Or for example pulling a DisplayName out of a people picker.

join(xpath(xml(json(concat('{"body":{"value":', item()?['value'], '}}'))), '/body/value/DisplayName/text()'), ', ')
