I want to replace the ProductVersion value at <DefineConstants> node of the following xml.

  • 0

I want to replace the ProductVersion value at <DefineConstants> node of the following xml. Remaining part of the line has to be preserved.
Example:

<DefineConstants>XXXXX;ProductVersion=20.323.23;YYYYY</DefineConstants>

to

<DefineConstants>XXXXX;ProductVersion=21.58.44;YYYYY</DefineConstants>

I tried the replaceregexp but it changes the remaining contents. 

<replaceregexp file="${basedir}\Installer.wixproj"
     match="ProductVersion=([0-9].*);(.*)"
     replace="ProductVersion=${SpaceVersion};\1"
     byline="true"
/>

Could you guide me what i am doing wrong in this.

    I think trying to capture the remainder of the line after the product version is unnecessary.

    You don’t need to worry about that. If your regex leaves the rest of the text alone, you can just replace the ProductVersion only.

    I had success with this:

    <replaceregexp file="${basedir}\Installer.wixproj"
    match="ProductVersion=[0-9]+\.?[0-9]+\.?[0-9]+\.?[0-9]+\.?;"
    replace="ProductVersion=${SpaceVersion};"
    byline="true"
    />
