stripping chars from property

[Henrik Gemal <sp...@mail.dk>]

I have the following:
<property file="ext.version" value="4.0.0" />

Now I need to create a file with the version in it's name but without 
the . (dots) something like:
blabla400.zip

So is there a way to convert the ${ext.version} into a new property 
without the dots?

I need this to be a generic way since I'm using the build.xml file in 
different places

Hello Henrik,

Here is one way to do this using ant-contrib[1] and
its task <propertyregex>[2]:

<project>
  <taskdef
  resource="net/sf/antcontrib/antcontrib.properties"/>
  <property name="ext.version" value="4.0.0"/>
  <propertyregex property="ext.version.undotted"
    input="${ext.version}"
    regexp="\." replace=""/>
  <echo>$${ext.version.undotted} is
${ext.version.undotted}</echo>
</project>

The output of this build file is:
[echo] ${ext.version.undotted} is 400.

There are also other ways to do it, like using
<scriptdef> and a scripting language like javascript
to do the string manipulation, but I think the one
above is the easiest.
