I noticed that the recent update of Mac OS X 10.5.8 breaks
compatibility with previous versions regarding XQuery statements in
NSXMLNode, specifically using the XQuery function tokenize. I
originally reported this bug against a future version of Mac OS X and
now seems to have slipped into the latest update of Mac OS X 10.5.
rdar://problem/7037807
The following code works on Mac OS X 10.5.0 - 10.5.7 but does not work
on Mac OS X 10.5.8.
@interface Bug7037807 : NSObject
{
NSXMLDocument* _document;
}
- (void)performXQuery:(NSString*)query;
@end
@implementation Bug7037807
- (id)init
{
if (self = [super init]) {
_document = [[NSXMLDocument alloc]
initWithXMLString:@"<html><title>title</title><body><h1>header</
h1><p>astring, bstring, cstring, dstring, estring</p><p>astring &
bstring & cstring & dstring & estring</p></body></html>"
options:NSXMLDocumentTidyHTML error:nil];
}
return self;
}
- (void)awakeFromNib
{
[self performXQuery:@"/descendant-or-self::p[1]"];
[self performXQuery:@"xs:string(/descendant-or-self::p[1])"];
[self performXQuery:@"tokenize(xs:string(/descendant-or-self::p[1]),
',')"];
}
- (void)performXQuery:(NSString*)query
{
NSError* __error = nil;
NSArray* __results;
__results = [_document objectsForXQuery:query error:&__error];
if (!__results) {
NSLog(@"error: %@", __error);
}
else {
NSLog(@"results: %@", __results);
}
}
@end

"invalid arguments to function - tokenize"
What does the 10.5.8 version of tokenize want as arguments? Any known
work-around?
