Count XML attributes

version 2003

Count XML attributes (elementRef) Longint

Parameter	Type		Description
elementRef	String		XML element reference
Function result	Longint		Number of attributes

The Count XML attributes command returns the number of XML attributes present in the XML element designated by elementRef. For more information about XML attributes, refer to the Presentation of XML commands section.

Before retrieving the values of elements in an array, you want to know the number of attributes in the following XML element:

   C_BLOB(myBlobVar)
   C_STRING(16;$xml_Parent_Ref;$xml_Child_Ref)
   C_TEXT(myResult)
   C_LONGINT($numAttributes)

   $xml_Parent_Ref:=Parse XML variable(myBlobVar)
   $xml_Child_Ref:=Get First XML element($xml_Parent_Ref)

   $numAttributes:=Count XML attributes($xml_Child_Ref)
   ARRAY TEXT(tAttrib;$numAttributes)
   For($i;1;$numAttributes)
      GET XML ATTRIBUTE BY INDEX($xml_Child_Ref;$i;tAttrib{$i})
   End for

In the above example, $numAttributes equals 3, tAttrib{1} contains "Font", tAttrib{2} contains "N" and tAttrib{3} contains "size".

Note: The index number does not correspond to the location of the attribute in the XML file displayed in text form. In XML, the index of an attribute indicates its position among the attributes arranged in alphabetical order (according to their name).

Count XML elements.

If the command has been correctly executed, the system variable OK is set to 1. If an error occurs, it is set to 0.
