		<Total>81678.600000</Total>
		<Invoice>
			<InvoiceNum>153</InvoiceNum>
			<Date>2013-03-01</Date>
			<Customer>2589</Customer>
			<Line>
				<ProductId>AT.02-2584</ProductId>
				<Description>Product 1</Description>
				<Quantity>1.000</Quantity>
				<UnitPrice>265.140000</UnitPrice>
			</Line>
		</Invoice>		
		<Invoice>
			<InvoiceNum>154</InvoiceNum>
			<Date>2013-03-01</Date>
			<Customer>2589</Customer>
			<Line>
				<ProductId>AT.02-2584</ProductId>
				<Description>Product 1</Description>
				<Quantity>1.000</Quantity>
				<UnitPrice>265.140000</UnitPrice>

filepath1 = "C:\Users\Documents\WorkP\March2013.xml"
       Dim XmlDoc As XDocument = RemoveXmlNamespace(XDocument.Load(filepath1))
        Dim query = From xe In XmlDoc.Descendants("Invoice")
              Where xe.Element("InvoiceNo").Value = "154"
              Select New With {
                 .Factura = xe.Element("InvoiceNo").Value,
                 .Cliente = xe.Element("CustomerID").Value,
                 .Produto = xe.Element("Line").Element("ProductCode").Value

look at line 8, instead of :

.Produto = xe.Element("Line").Element("ProductCode").Value

Open in new window

i used

.Produto = xe.Element("Line").Elements("ProductCode").Select(n=>n.Value)

Open in new window

so it returns for each line in the invoicenum, the ProductCode value.

Meir Rivkin

now that i look at the xml there's no ProductCode element inside Line element.
did u mean u have ProductId?

ASKER

I have two xml files one with ProductCode and another with ProductId. I'm a little confused (with Linq and Collections), what should put where is "n" in the code ".Select(n=>n.Value) ".

Meir Rivkin

I made a mistake, it should be:

.Produto = xe.Elements("Line").Select(n=>n.Element("ProductCode").Value)

Open in new window

this little linq code means loop through line elements and for each get productcode value.
The reason u got only the 1st one is cause u called xe.Element("Line") and not xe.Elements("Line").
xe.Element("Line") return the first one if exists.

ASKER

Sorry. Something is wrong with me. With the code provided ".Produto = xe.Elements("Line").Select(n=>n.Element("ProductCode").Value)", an error occurs saying "n is not declared".
