我有一个xml,如下所示:
<data>
<foo>value1</foo>
<foo>value2</foo>
<foo>value3</foo>
</data>
我想创建实现以下功能的macrodef:
<?xml version="1.0"?>
<project name="OATS" default="execute" basedir=".">
<xmlproperty file="data.xml" collapseAttributes="true"/>
<target name="execute">
<foreach list="${data.foo}" target="runScript" param="script"/>
</target>
<target name="runScript">
<echo>Doing things with ${script}</echo>
</target>
</project>
有谁知道怎么做?提前谢谢。

xmltask是Ant社区中用于此目的的最佳选择,您无需定义自己的macrodef。
例如:
<tools:xmltask source="data.xml" report="false" >
<tools:call path="data/foo">
<param name="value" path="text()"/>
<actions>
<echo>Doing things with @{value}</echo>
</actions>
</tools:call>
</tools:xmltask>
我鼓励您阅读用户手册,因为xmltask有很多选项。它基本上支持XPath来提取和迭代xml的任何部分。除了匿名代码块之外,它还支持对现有目标的调用(如示例所示)。
这很难被击败。

以下示例使用groovy ANT task
<project name="OATS" default="execute" basedir=".">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy">
<classpath>
<pathelement location="lib/groovy-all-2.1.0-rc-2.jar"/>
</classpath>
</taskdef>
<target name="execute">
<groovy>
def data = new XmlSlurper().parse(new File("data.xml"))
data.foo.each {
properties["script"] = it
ant.project.executeTarget("runScript")
}
</groovy>
</target>
<target name="runScript">
<echo>Doing things with ${script}</echo>
</target>
</project>

这是我的macrodef。
<?xml version="1.0" encoding="UTF-8"?>
<project name="OATS" default="test" basedir=".">
<property environment = "env"/>
<path id = "antcontrib.path">
<fileset file = "${env.ANT_HOME}/../net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar"/>
</path>
<taskdef resource="net/sf/antcontrib/antlib.xml" classpathref="antcontrib.path"/>
<macrodef name="runOATS">
<attribute name="suite"/>
<attribute name="toDir"/>
<sequential>
<delete dir="@{toDir}"/>
<mkdir dir="@{toDir}"/>
<xmlproperty file="@{suite}" collapseAttributes="true"/>
<for list="${data.foo}" param="script">
<sequential>
<runScript script="@{script}"/>
</sequential>
</for>
</sequential>
</macrodef>
<macrodef name="runScript">
<attribute name="script"/>
<sequential>
<echo>Doing things with @{script}</echo>
</sequential>
</macrodef>
<target name="test">
<runOATS toDir="/OATS/results" suite="data.xml"/>
</target>
</project>
