sed/awk string replacement with newline and tabs

I have an XML file that contains the following:
<ipaddr>192.168.1.1</ipaddr>
<subnet>24</subnet>
The goal is to modify <ipaddr>192.168.1.1</ipaddr> to <ipaddr>192.168.1.125</ipaddr> and <subnet>24</subnet> to <subnet>25</subnet> in one command. I do not want to change any other subnet tags inside the file.
The problem I have encountered is that there is a newline after </ipaddr> and there are two tabs before <subnet>.
I have tried this: awk '{gsub (/<ipaddr>192.168.1.1</ipaddr>n<subnet>24</subnet>/, "<ipaddr>192.168.1.125</ipaddr>ntt<subnet>25</subnet>")}' config.xml
but it does not work.
Could someone guide me in the right direction for this?

This is quite incomplete a specification. What are we going to search for? Some generic pattern? The exact IP address, and exact subnet? If yes, try
$ sed -r '/(192.168.1.)1/{s//1125/; N; s/24/25/}' file
<ipaddr>192.168.1.125</ipaddr>
<subnet>25</subnet>

If the IP is changed to124it will be again changed to125by the next substitution. Also, better use a limited subnet to be precise. Think what will hapen if the original subnet is 24 and the subnet change is4to8(for example). Finally, using-Eis POSIX compliant (and portable).

Assuming that you want to change the IP on one line and the sub-net on the next line:
sed -E '/(192.168.1.)1/{s//1125/; n; s/>24</>25</}' infile
That is not reporting any error if the IP is changed but the sub-net is not. Which seems to be what you want from your description.
