groovy - Sorting a resultset during the iteration over them -

given xml file following content

<root>   <group name="database">       <user name="thorsten"/>      <user name="karl"/>      <user name="beate"/>      <user name="heinz"/>      <user name="andreas"/>   </group> </root> 

now can read groovy script this

def out = ""; def result = new xmlslurper().parse(new file("d:\\user.xml")); result.group.user.each { out += it.@name.text()+ '\n'; } println out; 

the output in order appear in xml file

is possible sort, in alphabetic order, resultset during iteration on them?

georg

during iteration? of course not.

but if use xmlparser, this:

def doc = new xmlparser().parse(new file("users.xml")); foo = doc.group.user.sort { it.@name }.collect { it.@name }.join("\n") println foo 

which outputs:
