Hi -
I don't believe there's any concept of attribute ordering in XML (and
hence in any DOM implementation). See http://www.w3.org/TR/REC-xml/,
section 3.1

Jacob,
I've been looking at teh xmlproperty source. The order the task works
through attrs is driven by the order it comes from the DOM in
node.getAttributes():
if (node.hasAttributes()) {
NamedNodeMap nodeAttributes = node.getAttributes();
// Is there an id attribute?
Node idNode = nodeAttributes.getNamedItem(ID);
id = (semanticAttributes && idNode != null
? idNode.getNodeValue() : null);
// Now, iterate through the attributes adding them.
for (int i = 0; i < nodeAttributes.getLength(); i++) {
Node attributeNode = nodeAttributes.item(i);
if (!semanticAttributes) {
String attributeName =
getAttributeName(attributeNode);
String attributeValue =
getAttributeValue(attributeNode);
addProperty(prefix + attributeName,
attributeValue, null);
} else {
String nodeName = attributeNode.getNodeName();
String attributeValue =
getAttributeValue(attributeNode);
Being an XML person, perhaps you can answer some details that are not
in the javadocs.
1. What is the ordering in node.getAttributes() according to the
normative DOM specification?
2. If we want attributes in declaration order, how do we do it? Go
through all child nodes and only pick up things that are in the right
order.
3. Does the same ordering appear when running Ant with the older
version of Xerces?
XmlProperty is all dom based. If we cannot get stuff except in alpha
order, then we are going to have to live with it and document the fact.
