<p>I need to modify a (xml-)file from Apache Ant. "loadfile" task allows to load the file's content in a property. But how to store the property's value back to a file after its (property) modification?</p>

<p>Of course I could write custom task to perform this operation but I would like to know if there's some existing implementation.</p>

You can use the
echo
task.
```
```
<echo file="${fileName}" message="${xmlProperty}"/>
```
```
The
echoxml
task might be of interest to you as well.
