Dmitri Colebatch commented on XMLBEANS-267:
-------------------------------------------

Thanks Cezar - while you're in there, I might add another comment.  I was after a \
method to extract the attributes from a cursor and have this:

	private static Map extractAttributes(XmlCursor cursor)
	{
		Bookmark bookmark = new Bookmark();
		cursor.setBookmark(bookmark);
		if (cursor.isStartdoc())
			cursor.toNextToken();

		Map attributes = new HashMap();
		if (cursor.toFirstAttribute())
		{
			do
				attributes.put(cursor.getName(), cursor.getTextValue());
			while (cursor.toNextAttribute());
		}

		cursor.toBookmark(bookmark);
		return attributes;
	}

The part I found curious was that I had to call toFirstAttribute before calling \
toNextAttribute, which I can understand, but it doesn't really provide for what I \
would imagine would be the typical usage pattern.  It might be worth adding a comment \
on this in the javadoc as well.

> toFirstAttribute/toNextAttribute doesn't work

> 
> Key: XMLBEANS-267
> URL: http://issues.apache.org/jira/browse/XMLBEANS-267
> Project: XMLBeans
> Type: Bug

> Components: XmlObject
> Versions: Version 2.1
> Environment: Windows XP, Intel, Sun JRE 1.5.0_04
> Reporter: Dmitri Colebatch

> 
> Either I'm misinterpreting the expected usage of toNextAttribute, or it simply \
> doesn't work.  Here's my test code:  public static void main(String[] args) throws \
> Exception  {
> 		XmlObject xml = XmlObject.Factory.parse(new StringReader("<foo \
> a=\"x\"><bar>test</bar></foo>"));  XmlCursor cursor = xml.newCursor();
> 		boolean found = cursor.toFirstAttribute();
> 		System.out.println("found attribute: " + found);
> 	}
> And it outputs:
> 	found attribute: false
> I'm assuming this is a bug as the javadoc implies this should work.
