Hi,

I have a code like this:

Str toXML() {
   doc := XDoc
         {
            XElem("root")
              {
                XElem("number") { XText(number.toStr), },
                        XElem("tags") {
                            Tags.each |Tupla tupla, Str label| {
                                XElem("tag"),/* { XText(label.toStr), },*/
                            }
                        },
                 },
          }
   buf := StrBuf()
   doc.write(buf.out)
   return buf.toStr
 }

and when I run fan myfile.fan, I get:

/home/xan/proves/xitz/xitz-ng/xtz.fan(120,22): Invalid use of 'it' outside of it-block
ERROR: cannot compile script

(the line 120 is "XElem("tag")" line.

What's wrong.

Thanks in advance,

You're in a closure there - so your scope has changed - should be able to just assign to a local var (didn't try this):

XElem("tags") {
  temp := it
  Tags.each |tupla, label| {
    temp.add(XElem("tag"))
  }
}

Thank you very much, andy.
