Using Lua you can read anything, convert and set variables.

Can you give me some example with lua ?

https://www.google.nl/#q=nginx+lua+read+xml

http://viremo.eludi.net/LuaXML/

And then do something in a location block like:

set_by_lua $notused '
ngx.var.myroot = "default value";
if myuri == "www" then ngx.var.myroot = "someothervalue"; end;
';

But then of-course with a variable to be used in proxy_pass.

My xml is on local disk in c:/mystring.xml with this lines :

<Streamer>

<StringText>SomeURL</StringText>

</Streamer>

Please if you can show me how can I get text from StringText attribute ?

You read the file into an array,

dsarr = {};
local file = io.open("file.txt", "r");
for i = 1, count, 1 do
ds_line = file:read();
table.insert (dsarr, ds_line);

And while reading you could parse the line or later parse the array.

Though at http://viremo.eludi.net/LuaXML/ is a good example of using a library and being able to get a value from a xml attribute, once you have a variable simple do something like "ngx.var.myprox = xmlvar;"
inside nginx you do then proxy_pass $myprox;
