xmlReaderMoveToFirstAttribute() moves the xmlReader on to the
first attribute of the current element, which makes it the target of
<$ret = (xmlReaderMoveToFirstAttribute($reader))>
<while $ret eq 1>
<$name = (xmlReaderGetName($reader))>
<$content = (xmlReaderGetContent($reader))>
attr '$name' = '$content'
<$ret = (xmlReaderMoveToNextAttribute($reader))>
The ordering of the attributes as provided by this function might NOT be the same as the ordering of the attributes in the XML document. This is legal, as the ordering of attributes is not significant in an XML document (see section 3.1 of the XML spec).
