It always depends on the rules and the structure of the contents
you are converting, but when someone says "I want to traverse this
hierarchy looking for ...", then apply-templates/mode is normally
a pretty good answer.

Thanks Phil! I wasn't aware of the mode statement. However, as I don't
see a performance benefit, then solution in my initial e-mail looks
bit simpler.

Use apply-templates and a distinct mode to traverse the entire
hierarchy and apply rules to rebuild content, like:

version 1.2;

main  {
var $alphabet :=  {
 {
 "bbb  ";
 "ccc  ";
}
 {
 "ddd  ";
 "fff  ";
}
}

var $new = {
apply-templates $alphabet {
mode "trim";
}
}

 { copy-of $new; }
}

match text() {
mode "trim";

if (name(..) == "d") {
 translate(., " ", "");
} else {
copy-of .;
}
}

match @* | * | processing-instruction() | comment() {
mode "trim";

copy-node {
apply-templates * |@* | text() | processing-instruction() | comment() {
mode "trim";
}
}
}

[j-nsp] How to trim the text node of a specific element node in SLAX node-set?

2018-10-24 Thread Martin T 
Hi!

I need to trim the text node of a specific element node in SLAX. All
other elements should remain as in the original node-set. At the
moment, I do it like this:

$ cat trim_node-set.slax
version  1.2;

main  {

  var $alphabet := {
 {
   {
 "bbb  ";
 "ccc  ";
  }
   {
 "ddd  ";
 "fff  ";
  }
}
  }

  var $alphabet_trimmed := {
 {
  for-each ( $alphabet/letters/consonants ) {
 {
  for-each ( * ) {
if ( name() == "d" ) {
   translate(.," ", "");
}
else {
  copy-of .;
}
  }
}
  }
}
  }

  copy-of $alphabet_trimmed;
}
$

As seen above, if element node is , then space characters are
removed. Output of this script can be seen below:

$ slaxproc -g -E trim_node-set.slax


  

  bbb  
  ccc  


  ddd
  fff  

  

$

Is there a more elegant way to do this? In addition, if I do the same
for rpc-reply, then for some reason, every element node gets the
'xmlns:junos="http://xml.juniper.net/junos/*/junos;' attribute node.
Just out of curiosity, why does this happen? As seen in the output
above, this does not happen in slaxproc, i.e ,  and  do not
get any attribute nodes added.


thanks,
Martin
