Question

我是groovy的新手。我试图运行这个时髦的脚本：

def inxml = "<?xml  version='1.0' encoding='UTF-8' standalone='yes'  ?> <doc><extension source='ExtractTextStage'>" +                 
 "<field name='DC.Date.Modified'>2006-04-13</field><field  name='dc.date'>01-01-2016</field><field  name='dc.language'>EN</field></extension>"+
 "<extension source='you'>" +                 
 "<field  name='dc.date'>02-02-2015</field><field  name='dc.language'>EN</field></extension></doc>"

 def doc = new XmlSlurper().parseText(inxml)

 def date = doc.extension.find{ extension-> extension.@source='ExtractTextStage'}.field.find { field->field.@name == "DC.Date.Modified" }

 doc.add("last_modified", date)

 print doc;

但我收到此错误：

groovy.lang.MissingMethodException: No signature of method: groovy.util.slurpersupport.NodeChild.add() is applicable for argument types: (java.lang.String, groovy.util.slurpersupport.NodeChild) values: [last_modified, 2006-04-13]
Possible solutions: any(), wait(), name(), pop(), min(), tail()
    at Script1.run(Script1.groovy:10)

我想添加一个名为＆＃34; last_modified＆＃34;的新字段。在我的XML中，并为其分配与＆＃34; DC.Date.Modified＆＃34;相同的值。场价值。任何帮助将不胜感激。

认为你需要做这样的事情：

def inxml = '''<?xml  version='1.0' encoding='UTF-8' standalone='yes'?>
              |<doc>
              |    <extension source='ExtractTextStage'>
              |        <field name='DC.Date.Modified'>2006-04-13</field>
              |        <field  name='dc.date'>01-01-2016</field>
              |        <field  name='dc.language'>EN</field>
              |    </extension>
              |    <extension source='you'>
              |        <field  name='dc.date'>02-02-2015</field>
              |        <field  name='dc.language'>EN</field>
              |    </extension>
              |</doc>'''.stripMargin()

def doc = new XmlSlurper().parseText(inxml)

def date = doc.extension
              .find { extension -> extension.@source='ExtractTextStage'}
              .field
              .find { field -> field.@name == "DC.Date.Modified" }

def newNode = new XmlSlurper().parseText("<last_modified>$date</last_modified>")

doc.appendNode(newNode)

println groovy.xml.XmlUtil.serialize(doc)

groovy.lang.MissingMethodException：没有方法签名：groovy.util.slurpersupport.NodeChild.add（）
