How to use Special Characters in CONCAT function or another form with Xquer

Question

Hello everyone
I'm using PS3 OEPE within message flow (proxy)and I'm using Xquery.
I'm using the CONCAT function, but this does not allow me to concatenate special characters not allowed, for example:
I want to concatenate these strings:
String1 = “<get-person><id-person&;gt;”
String2 = “123”
String3 = “</id-person&;gt; </get-person>”
I want to represent characters regex. It means no XML characters
Someone knows some way, any function that allows me to concatenate in OSB these values with Xquery?

Hi,
It seems to me you're doing things in the most complicated way possible...
Firstly, you should use codepoints-to-string not the reverse... Secondly, the function work with decimals, not hexa
http://www.xqueryfunctions.com/xq/fn_codepoints-to-string.html
http://www.xqueryfunctions.com/xq/fn_string-to-codepoints.html
This works...
concat(codepoints-to-string(38),'lt',codepoints-to-string(59),'get-person')But this also works... Note that I've inserted a space between the & and the lt so the forum formatting can show it...
let
$String1 := "& lt;get-person& gt;& lt;id-person& gt;",
$String2 := "123",
$String3 := "& lt;/id-person& gt;& lt;/get-person& gt;"
return
     concat($String1,$String2,$String3)And, finally this also works... So what's the reason for escaping < and > with &lt and > and why codepoints?
let
$String1 := "<get-person><id-person>",
$String2 := "123",
$String3 := "</id-person></get-person>"
return
     concat($String1,$String2,$String3)Cheers,
