Maven Ant 中截取字符串

在ant中，无法实现常见的字符串操作，比如截取、替换。我们可以借助ant-contrib中实现字符串的截取、替换.

下面的例子是在maven中运行ant，ant中来做字符串截取，我们从一个txt中读取字符串，并使用回车换行进行字符串的分割。

				<for list="${strfile}" delimiter="&#xD;&#xA;" param = "val">
                                    <sequential><echo message = "val = @{val}"/></sequential>
