@XMLPUTATTR[name,namespaceURI,value] : Writes an XML attribute
@XMLPUTATTR writes an XML attribute on the currently opened XML element. It must be called right after calling @XMLSTARTELEMENT and before any calls to @XMLPUTSTRING, @XMLPUTCOMMENT, or @XMLPUTRAW. The file must have been opened with a previous @XMLOPEN.
If name is a local name without a prefix, the class will automatically introduce a new xmlns="NamespaceURI" attribute if necessary.
If name is in the form prefix:local, then class will automatically introduce a new xmlns:prefix="NamespaceURI" as necessary.
Certain attribute names will be handled in special ways by this method. If name is "xmlns" or uses the "xmlns" prefix, the attribute will be interpreted as a namespace declaration, regardless of the value of NamespaceURI. Similarly, any attribute using the "xml" prefix will be interpreted as a special attribute (like "xml:lang") and NamespaceURI will be ignored.
Returns 0 on success, or an XML error on failure.
Example:
To create this XML named books.xml:
<book xmlns='urn:loc.gov:books' xmlns:isbn='urn:ISBN:0-395-36341-6'>
<title>Cheaper by the Dozen</title>
<isbn:number>1568491379</isbn:number>
</book>
Use the code:
echo %@xmlcreate[books.xml]
echo %@xmlstartelement[book,urn:loc.gov:books]
echo %@xmlputattr[xmlns:isbn,"",urn:ISBN:0-395-36341-6]
echo %@xmlputelement[title,urn:loc.gov:books,Cheaper by the Dozen]
echo %@xmlputelement[isbn:number,urn:ISBN:0-395-36341-6,1568491379);
echo %@xmlendelement[]
echo %@xmlclose[]
