IXMLReader.Attributes Property
Attributes of current element.
Public ReadOnly Property Attributes As IXMLAttributes
public IXMLAttributes Attributes {get;}
IXMLReader.CloseElement Method
Moves position to parent element.
Public Sub CloseElement ( _
)
public void CloseElement (
);
IXMLReader.HasElementChildren Property
Indicates whether the current element has child elements.
Public ReadOnly Property HasElementChildren As Boolean
public bool HasElementChildren {get;}
IXMLReader.IsLastChild Property
Indicates whether the current element is the last child element of its parent.
Public ReadOnly Property IsLastChild As Boolean
public bool IsLastChild {get;}
IXMLReader.LocalName Property
Local name of current element.
Public ReadOnly Property LocalName As String
public string LocalName {get;}
IXMLReader.LookupPrefix Method
Obtains the prefix for a declared URI.
Public Function LookupPrefix ( _
ByVal Prefix As String _
) As String
public string LookupPrefix (
string Prefix
);
IXMLReader.NamespaceDeclarations Property
Namespace declarations of current element.
Public ReadOnly Property NamespaceDeclarations As IXMLNamespaces
public IXMLNamespaces NamespaceDeclarations {get;}
IXMLReader.NamespacePrefix Property
Namespace prefix of current element.
Public ReadOnly Property NamespacePrefix As String
public string NamespacePrefix {get;}
IXMLReader.NamespaceURI Property
Namespace URI of current element.
Public ReadOnly Property NamespaceURI As String
public string NamespaceURI {get;}
IXMLReader.NextElement Method
Moves position to next element.
Public Sub NextElement ( _
)
public void NextElement (
);
IXMLReader.OpenElement Method
Moves position to first child element.
Public Sub OpenElement ( _
)
public void OpenElement (
);
IXMLReader.ReadBinary Method
Reads the current element value as a binary array.
Public Function ReadBinary ( _
) As Byte[]
public Byte[] ReadBinary (
);
Remarks
The ReadBinary method specifies the current element value as a binary array.
IXMLReader.ReadBoolean Method
Reads the current element value as a boolean.
Public Function ReadBoolean ( _
) As Boolean
public bool ReadBoolean (
);
Remarks
The ReadBoolean method specifies the current element value as a boolean.
Element value 1 or true will return boolean value of true, anything else will return false.
IXMLReader.ReadByte Method
Reads the current element value as a byte.
Public Function ReadByte ( _
) As Byte
public byte ReadByte (
);
Description
Remarks
The ReadByte method specifies the current element value as a byte.
Byte variables are stored as single, unsigned 8 bit numbers (1 byte), its range is from 0 to 255. Anything below and above these numbers will cause the Invalid Procedure Call Error.
IXMLReader.ReadDate Method
Reads the current element value as a date.
Public Function ReadDate ( _
) As DateTime
public DateTime ReadDate (
);
Remarks
The ReadDate method specifies the current element value as a date.Date value in xml file should be only of this format:2005-01-28T12:17:58otherwise the ReadDate will invoke Invalid Procedure Call Error.Example of "data.xml" file:
<?xml version="1.0"?><Data description="example of ReadDate"><type><date>2005-01-28T12:23:34</date>
</type>
</Data>
VB6 code to get date value:
Dim pXMLStream As IXMLStreamSet pXMLStream = New XMLStreampXMLStream.LoadFromFile App.Path + "\data.xml"pXMLReader.OpenElementpXMLReader.OpenElementDim dateValue As DatedateValue = pXMLReader.ReadDate
IXMLReader.ReadDouble Method
Reads the current element value as a double.
Public Function ReadDouble ( _
) As Double
public double ReadDouble (
);
Remarks
The ReadDouble method specifies the current element value as a double.
IXMLReader.ReadFloat Method
Reads the current element value as a float.
Public Function ReadFloat ( _
) As Single
public float ReadFloat (
);
Remarks
The ReadFloat method specifies the current element value as a float.
IXMLReader.ReadFrom Method
Specifies the input XML stream.
Public Sub ReadFrom ( _
ByVal inputStream As IStream _
)
public void ReadFrom (
IStream inputStream
);
Remarks
The ReadFrom method specifies the input XML stream.
For example:
Dim pXmlReader As IXMLReaderSet pXmlReader = New XMLReader
Dim pXmlStream as IXMLStreamSet pXmlStream = new XMLStream
pXmlStream.OpenFromFile App.Path & "\file.xml"pXmlReader.ReadFrom pXmlStream
If xml file is empty the XMLStream will evoke Automation error. Xml file needs to be of a proper structure.
IXMLReader.ReadInteger Method
Reads the current element value as a long.
Public Function ReadInteger ( _
) As Integer
public int ReadInteger (
);
Remarks
The ReadInteger method specifies the current element value as a Integer.
IXMLReader.ReadShort Method
Reads the current element value as a short.
Public Function ReadShort ( _
) As Short
public short ReadShort (
);
Remarks
The ReadShort method specifies the current element value as a short.

Reads the current element value as a variant.
Public Function ReadVariant ( _
) As Object
public object ReadVariant (
);
Remarks
The ReadVariant method specifies the current element value as a variant.
