Procedure Test
    Handle hoXml
    Boolean iAutoCreate
    Boolean iSuccess
    String sTemp1

    // Note: This example requires Chilkat v9.5.0.64 or later.
    Get Create (RefClass(cComChilkatXml)) To hoXml
    If (Not(IsComObjectCreated(hoXml))) Begin
        Send CreateComObject of hoXml
    End

    Set ComTag Of hoXml To "animals"

    Move True To iAutoCreate

    // When the autoCreate argument equals True, the UpdateAttrAt
    // method auto-creates the children as needed:

    Get ComUpdateAttrAt Of hoXml "mammal|rodent|squirrel" iAutoCreate "feature" "bushy tail" To iSuccess
    Get ComUpdateAttrAt Of hoXml "mammal|rodent|rat" iAutoCreate "feature" "long hairless tail" To iSuccess

    // Show the XML
    Get ComGetXml Of hoXml To sTemp1
    Showln sTemp1
