Yesterday I needed to uncomment multiple lines in the applicationcontext of a Prana XML. After some searching I found the Ant Task I needed: replaceregexp.

Threre were four blocks that I needed to uncomment:

1

	</object>

I couldn’t just search for and replace it by because there were childnodes that had to stay uncommented.

So here are the replaceregexp tasks that made it work:

	<substitution expression="&lt;!--value&gt;

				&lt;/object&gt;

</replaceregexp>

</replaceregexp>
<replaceregexp file="${selor-salto-test-deploy-folder.dir}/backend/application-context-backoffice.xml"
	byline="false" flags="s">

	<substitution expression="MetaDataContentModule.swf&quot; /&gt;

				&lt;/object&gt;
			&lt;/value--&gt;"/>
</replaceregexp>

The thing me and a colleague searched on for a while was the s flag that was needed to make it work. I will try the other flags because I’m really not sure what this s flag means… (trial and error yeah!). I’ve seen that after the task ran the layout was messed up (no newlines anymore in the replaced text).

The .{1,150} means that a maximum of 150 characters may occur between for example MetaDataContentModule.swf and </value>.

Ciao!
