Groovy xml基于父模式属性选择子节点属性

Question

我有一个像这样的xml结构

<JJJ version="2.0" >
<Data >
 <Object class="classX">
  <k name="constname1">variable1</p>
  <k name="constname2">variable2</p>
  <k name="constname3">variable3</p>
</Object>
 <Object class="classY">
  <k name="constname1">variable11</p>
  <k name="constname2">variable12</p>
  <k name="constname3">variable13</p>
</Object>

我需要选择ClassX节点，并在包含constname1（即variable1）AttAttribute的值中

def parser = new XmlSlurper()
def mymo=records.'Data'.'Object';
def mytest =  mymo.findAll{[e-mail]()=="ClassX"};
mytest.each{
it.'p'.each{
  println  [e-mail]() +'-'+ it.text() }
 }

这起作用了。但是，我需要做如下操作，而不是在循环中混合文本

def testme= mytest.'k'.find{ [e-mail]()=="constname1"}

这是我不对的

然而下面是正确的

      println mymo.'k'.find{[e-mail]()=="constname1"}

但我希望将选择范围限制为classX的节点

更正xml以使其有效,可以得到：

def xml = '''<JJJ version="2.0" >
            |  <Data >
            |    <Object class="classX">
            |      <k name="constname1">variable1</k>
            |      <k name="constname2">variable2</k>
            |      <k name="constname3">variable3</k>
            |    </Object>
            |    <Object class="classY">
            |      <k name="constname1">variable14</k>
            |      <k name="constname2">variable15</k>
            |      <k name="constname3">variable16</k>
            |    </Object>
            |    <Object class="classX">
            |      <k name="constname1">variable7</k>
            |      <k name="constname2">variable8</k>
            |      <k name="constname3">variable9</k>
            |    </Object>
            |  </Data>
            |</JJJ>'''.stripMargin()

List var = new XmlSlurper().parseText( xml ).'**'.grep { 
  it.@name == 'constname1' && it.parent().@class == 'classX'
}

assert var == [ 'variable1', 'variable7' ]

这是你想要的吗？
