The following SB code and XML code work OK in PureBasic, but in SpiderBasic the debug message after the call to MainXMLNode never appears. It's like MainXMLNode never returns.

Code: Select all

hXML = LoadXML(#PB_Any,"TestXML.xml")
If hXML
  If IsXML(hXML)
    Debug "IsXML OK"
    If XMLStatus(hXML) = #PB_XML_Success
      Debug "XMLStatus OK"
      Debug "Calling MainXMLNode"
      hParent = MainXMLNode(hXML)
      Debug "MainXMLNode returned"
      If hParent
        Children = XMLChildCount(hParent)
        Debug "Parent has " + Str(Children) + " children"
        hChild = ChildXMLNode(hParent)
        GrandChildren = XMLChildCount(hChild)
        Debug "First child has " + Str(GrandChildren) + " chldren"
      EndIf
    Else
      Debug "XMLStatus Failed, " + XMLError(hXML)    
    EndIf
  Else
    Debug "IsXML failed, " + XMLError(hXML)
  EndIf
Else
  Debug "LoadXML(#PB_Any,'TestXML.xml') failed"
EndIf

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<Parent>
	<Child>Child1
  	<GrandChild>GrandChild1</GrandChild>
  	<GrandChild>GrandChild2</GrandChild>
  	<GrandChild>GrandChild3</GrandChild>
  	<GrandChild>GrandChild4</GrandChild>
  	<GrandChild>GrandChild5</GrandChild>
	</Child>
	<Child>Child2
  	<GrandChild>GrandChild1</GrandChild>
  	<GrandChild>GrandChild2</GrandChild>
  	<GrandChild>GrandChild3</GrandChild>
  	<GrandChild>GrandChild4</GrandChild>
  	<GrandChild>GrandChild5</GrandChild>
	</Child>
</Parent>

Thanks for quick response. I did a search for Loading in SB help and didn't come up with anything although I do see Loading procedures in examples. I don't see a call to Loading so I presume the LoadXML call somehow triggers it internally. Where can I find more documentation on what SB calls require Loading procedures, and how such seemingly asynchronous loading behavior is typically synchronized?
