Remarks
The DeletePropertyByNameAndAttribute method provides additional parameters to delete XML elements and their corresponding values from metadata documents. Similar actions can be accomplished through other methods (DeleteProperty, DeletePropertyByAttribute) and XPath strings. For instance the following lines of pseudocode accomplish the same action;
xmlPropertySet.DeletePropertyByNameAndAttribute("idinfo/keywords/theme/themekey", "new", "yes", False)
xmlPropertySet.DeleteProperty("idinfo/keywords/theme/themekey[@new='yes']")
The Name parameter uses XPath to describe the location and condition of XML nodes in metadata. More information on XPath can be found at the IXmlPropertySet documentation.
If children elements of the specified Name parameter exist, the DeletePropertyByNameAndAttribute method will also remove them from the XML Document.
The Attribute parameter must contain a valid string character. Otherwise the DeleteProperty method should be used for deleting elements without having to specify attributes.
By setting the attribute Value parameter to "", all elements that match the Name and Attribute parameter will be deleted. The DeletePropertyByAttribute method should be used to delete elements without specifying attribute values.
The deleteParent parameter is a Boolean expression that indicates if the parent element of the Name parameter should be deleted. Special attention should be made to this parameter when deleting a Thumbnail or Binary Enclosure. The parent of the Thumbnail element is the Enclosure element, which also happens to be a parent element of the Data element that holds the Binary information. If deleteParent is set to true when specifying the Data or Thumbnail tag, all Enclosures information will be removed.
