Replace in File w/ Macro Value

[draymond]

Text or regular expression to find:

<row><td>C:\Build Area\1.2.3.4</td><td>

Text or regular expression to replace matches with:

<row><td>C:\Build Area\1.2.3.5</td><td>

I would like to replace 1.2.3.4 will the macro of the build version. I am uncertain how to use macros with the "Text or regular expression to replace matches with". Thanks.

UPDATE:
Use Text or regular expression to replace matches with:
<row><td>C:\Build Area\%MACRO_NAME%</td><td>

RELATED PROBLEM:
But how do I select just a select group of characters to replace?
<row><td>C:\Build Area\REPLACEME</td><td>

This does not work for me.
^<row><td>C:\Build Area\\.*?</td><td>$
