CoClasses that implement IXMLAttributes

CoClasses and Classes Description
XMLAttributes A collection of XML element attributes.

Remarks

In XML (as well as in HTML) attributes provide additional information about elements.

For example,

<software cpu="800 Mhz" min_memory="256 mb" rec_memory="512 mb">ArcInfo</software >

Software element has cpu, min_memory, and rec_memory attributes that specify hardware requirements for ArcInfo.

Use the AddAttribute method to add new attributes to the element, the DeleteAttribute method to remove any unwanted attributes from the attribute list. The FindAttribute method searches for the attribute based on its local name (in our case: cpu, min_memory, or rec_memory) and its namespace URI (Unique Resource Identifier), and returns the index at which the searched attribute was found. The AttributeCount  property returns number of attributes in the list. The LocalName, NamespaceURI, and Value  properties return local name, URI, and value of the attribute.

Example (VB6):

  Dim pXMLAttributes As IXMLAttributes
  Set pXMLAttributes=new XMLAttributes

   '*** Add a few attributes to the attribute list ***
  pXMLAttributes.AddAttribute "first", "", "First name"
  pXMLAttributes.AddAttribute "last", "", "Last name"
  pXMLAttributes.AddAttribute "middle", "", "Middle name"

  '*** Remove the middle name attribute ***
  pXMLAttributes.DeleteAttribute "middle", ""

  '*** Count the number of attributes in the list ***
  Dim count as Long
  count=pXMLAttributes.AttributeCount

  '*** Get the index of the Last name attribute ***
  Dim index as Long
  index=pXMLAttributes.FindAttribute "last", ""

  '*** Get local name, uri, and value ***
  Dim localName as String
  Dim uri as String
  Dim value as String

  localName=pXMLAttributes.LocalName(index)
  uri=pXMLAttributes.NamespaceURI(index)
  value=pXMLAttributes.Value(index)< /P >< /P >
