I'm trying to collect data from a web service. The xml data has this format:

<?xml version="1.0" encoding="UTF-8"?>
<Result>
<UserStatus Status="2" StatusFrom="230904080005" ClientType="13,16" Device="tel:0123456789" TerminalCapabilities="1" DeviceStatusFrom="231204092543" OfficeDeviceStatusFrom="230918121327" MobileDeviceStatusFrom="231204092543" ServerTime="231204155632" DisplayName="Full Name">mailaddress@example.com</UserStatus>
</Result>

When using DCI parameter WebService1:/Result/UserStatus, I get mailaddress@example.com returned.
When trying to collect the value of an attribute, for example WebService1:/Result/UserStatus/Status, I get <<ERROR>> instead of the value 2.

Is the XML parser in NetXMS compliant with the XML standard?
When testing on xmlvalidation.com it says No errors were found, and this PowerShell oneliner demonstrates it should work:

([xml]'<Result><UserStatus Status="2"/></Result>').Result.UserStatus.Status

Thanks in advance.
