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>

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.
