[jira] Created: (XMLBEANS-267) toFirstAttribute/toNextAttribute
doesn't work
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.

[jira] Commented: (XMLBEANS-267) toFirstAttribute/toNextAttribute
doesn't work

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.

[jira] Closed: (XMLBEANS-267) toFirstAttribute/toNextAttribute
doesn't work
Posted by "Cezar Andrei (JIRA)" <xm...@xml.apache.org>.
[ http://issues.apache.org/jira/browse/XMLBEANS-267?page=all ]
Cezar Andrei closed XMLBEANS-267:
---------------------------------
Resolution: Fixed
The method XmlCuresor.toFirstAttribute() works from two states:
1. on START - goes to the first attribute of that element if one exists
2. on STARTDOC - goes to the first top level attribute of a document fragment - if STARTDOC is a docfrag and a top level attribute exists.
I'll add this comment to the java doc.
