I'm assuming that you want to sort the "page" elements into ascending order based on the value of each elements' "number" attribute? This will do that and save the modified XML file at the end. $x = @' '@ $xml = [xml]$x $SortedPageElements = $xml.pages.page | sort {[int]$_.number} $xml.pages.page | ForEach-Object{ $_.ParentNode.RemoveChild($_) | Out-Null } $SortedPageElements | ForEach-Object{ $xml.DocumentElement.AppendChild($_) | Out-Null } $xml.Save('c:\junk\new.xml')Note that the new file will have numeric values for the "number" attributes' value. The XML you posted has text values and if you sort those you won't have the sort turn out the way I think you want it to. |
