Xpath and arrays with apply to each

Hello!

 

I have an XML file which I want to parse to an e-mail message.

 

...

 

Action: Data Operation -> Compose: Produtcnames

 

 

 

xpath(xml(outputs('ValidXML')), '/invoice/items/item/productname')

 

 

 

 

Action: Control -> Apply for each: Apply for each product name

Selected output: outputs('Productnames')

      Action: Variable -> Increment variable: Increase product ID

                   Name: ProductID
                   Value: 1

 

      Action: Variable -> Append to array variable:  Add to productsArray

 

 

 

{
"No.:": @{variables('ProductID')},
"Product": @{replace(replace(decodeBase64(item()?['$content']),'<productname>',''),'</productname>','')}
}

 

 

 

 

The code above is working fine but I have an another step:

Action: Data Operation -> Compose: ProductPrices

 

 

 

xpath(xml(outputs('ValidXML')), '/invoice/items/item/productprice')

 

 

 

 

So I would like to modify

  Action: Variable -> Append to array variable:  Add to productsArray

 

 

 

{
"No.:": @{variables('ProductID')},
"Product": @{replace(replace(decodeBase64(item()?['$content']),'<productname>',''),'</productname>','')},
"Price": @{replace(replace(decodeBase64(item()?['$content']), '<productprice>', ''), '</productprice>', '')}
} 

 

 

 

 

 

But only the item() function can not be changed to

 

 

 

replace(replace(decodeBase64(outputs('ProductPrices')?['$content']), '<producprice>', ''), '</producprice>', '')

 

 

 

Here is the xml:

 

<?xml version="1.0" encoding="utf-8" ?>
<invoice>
	<items>
		<item id="5">
			<productname>Product one</productname>
			<productprice>1000</productprice>
		</item>
		<item id="7">
			<productname>Product two</productname>
			<productprice>9000</productprice>
		</item>
	</item>
</invoice>

Hi
Each xml item has a single Product Name, right?. Did you try to iterate through xml items instead of iterating through xml Product names?
Inside each iteration you should be able to grab current item's product name, product price, and append a new element to your array
Hope this helps
