Question

我有另一张地图问题。这是地图格式的问题，我似乎无法做到正确。这是XML：

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
 <SearchRS>
     <SearchStatus>SUCCESS</SearchStatus>
     <Itinerary>
         <Carrier>Joe</Carrier>
         <Total>111.11</Total>
         <Duration>111</Duration>
     </Itinerary>
     <Itinerary>
         <Carrier>Bob</Carrier>
         <Total>222.22</Total>
         <Duration>222</Duration>
     </Itinerary>
     <Itinerary>
         <Carrier>Joe</Carrier>
         <Total>333.33</Total>
         <Duration>333</Duration>
     </Itinerary>
     <Itinerary>
     <Itinerary>
          <Carrier>Bob</Carrier>
          <Total>444.44</Total>
          <Duration>444</Duration>
     </Itinerary>
          <Carrier>Joe</Carrier>
          <Total>234.10</Total>
          <Duration>167</Duration>
     </Itinerary>
 </SearchRS>

我想创建一个看起来像这样的简单地图：

[[carrier：Joe，cost：111.11，duration：111]，[carrier：Bob，cost：222.22，duration：222]，[carrier：Joe，cost：333.33，duration：333]，[carrier：Bob] ，费用：444.44持续时间：444]，[承运人：乔，费用：234.10，工期167]]

我所看到的是：

[[Joe：[111.11,333.33,234.10]，Bob：[222.22,444.44]]

这是我的代码，例如它;

 def carriers = [:]
 for (name in doc.'**'.findAll { it.name() == 'CarrierCode' }.unique()) {
        carriers[name] = doc.'**'.findAll { it.name() == 'Itinerary' && name == it.CarrierCode.text() }.collect {
        Double.parseDouble(it.DisplayTotal.text()) + Double.parseDouble(it.Duration.text())
      }
 }
 log.info("map is " + carriers)

我需要这些地图上的帮助，直到我能进入一个时髦的课程，我真的坚持这些事情，所有人都非常感谢！

您不仅要构建地图，还要构建地图列表

def xml='''<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
 <SearchRS>
     <SearchStatus>SUCCESS</SearchStatus>
     <Itinerary>
         <Carrier>Joe</Carrier>
         <Total>111.11</Total>
         <Duration>111</Duration>
     </Itinerary>
     <Itinerary>
         <Carrier>Bob</Carrier>
         <Total>222.22</Total>
         <Duration>222</Duration>
     </Itinerary>
     <Itinerary>
         <Carrier>Joe</Carrier>
         <Total>333.33</Total>
         <Duration>333</Duration>
     </Itinerary>
     <Itinerary>
     <Itinerary>
          <Carrier>Bob</Carrier>
          <Total>444.44</Total>
          <Duration>444</Duration>
     </Itinerary>
          <Carrier>Joe</Carrier>
          <Total>234.10</Total>
          <Duration>167</Duration>
     </Itinerary>
 </SearchRS>'''
def doc=new XmlSlurper().parseText(xml)
doc.Itinerary.collect{
    [
        carrier:  it.Carrier,
        cost:     it.Total.toBigDecimal(),
        duration: it.Total.toBigDecimal(),
    ]
}

Answer 2

尝试使用此代码：

def root = new XmlSlurper().parse(new File ('/tmp/stack.xml'))

List <Map> totalresult = []

root.'**'.findAll{ it.name() == 'Itinerary'}.each{

    Map temp = [:]

    temp [it.Carrier.name()] = it.Carrier.text()

    temp [it.Total.name()] = it.Total.text()

    temp [it.Duration.name()] = it.Duration.text()

    totalresult << temp
}

println totalresult
