Try this: 

mystring.substring(mystring.lastIndexOf("at /")+4, mystring.lastIndexOf("/@"))

but you probably should use a more generic solution. To extract all the section that have this format you can use something like this:

String mystring = "<EQHO state=\"degraded\"...> at /NE[1]/EQHO[2]/@state to <EQHO state=\"working\"...> at /NE[1]/EQHO[1]/@state";
ArrayList<String> values = new ArrayList<String>();
while(mystring.indexOf("at /") < mystring.indexOf("/@")){
    String val = mystring.substring(mystring.indexOf("at /") + 4, mystring.indexOf("/@"));
    values.add(val);
    mystring = mystring.substring(mystring.indexOf("/@")+2);
}
System.out.println(values);

You can change the value of a string like this

mystring = "NE[1]/EQHO[1]";

Remember to include the semicolon!
