There is no need to do this for java >= 1.4.

You may need to "quote the quotes"(tm)
Your regex has &gt;, &quot; etc, if these are in the regex you tested
with grep, they need to be quoted for ant (as ant uses XML).

the \\ may need to be replaced with just a single \.
as the \\ is to escape the \ for the shell with using grep
"(&amp;lt;img src=\&amp;quot;)([^\.]+\.svg)(\&amp;quot;/?&amp;gt;)"/
of course it now looks completely like line noise. (xml/regex/xml encoding)

It may be better to use a task that is designed for xml processing:
like: xmltask - http://www.oopsconsultancy.com/software/xmltask/
or use xslt.

if the regex does not match anything, nothing happens.
