XPath sorting
For some reason I've ended up with a list of (xpath, char content)
pairs for every node in an XML document and need to recreate the
original document using these. This is easy, I can sort it
alphabetically and then create the nodes in the right order. Apart
from annoying /foo/bar[1]/quux, /foo/bar[2]/quux, ..., /foo/bar[10]/quux not sorting in the right order. I currently work
around it as in the code below. Is there an other way I could do this?
It seems a little hacky to have to change them all to /foo/bar/[00004]/quux to sort it...
sub xpath_sort {
my($self, @xpaths) = @_;
my %canon;
foreach my $xpath (@xpaths) {
my $c = $xpath;
$c =~ s{\[(\d+)\]}{'[' . sprintf("%05d", $1) . ']'}e;
$canon{$xpath} = $c;
}
@xpaths = sort { $canon{$a} cmp $canon{$b} } @xpaths;
return @xpaths;
}
XPath rocks. I can't imagine XML without it anymore...

Why not create triplets (XPath, char content, order number) instead of just pairs?

I don't think there's a solution to your problem, apart from having a way of creating the nodes not in order (and using ghost nodes) which would be a great thing to have.

Be careful... you're getting very dangerously close to liking XSLT...
