这是xml-data:

<DATA VERSION="1.0">
  <TABLES>
    <ITEM>
      <identifyer V="1234"></identifyer>
      <property1 V="abcde"></property1>
      <Property2 V="qwerty"></property2>
    </ITEM>
    <ITEM>
      <identifyer V="5678"></identifyer>
      <Property1 V="zyxwv"></property1>
      <Property2 V="dvorak"></property2>
    </ITEM>
  </TABLES>
</DATA>

我试图找到有价值property2的项目.我可以选择数据:identifyer1234

$ xmlstarlet sel -t -c "/DATA/TABLES/ITEM/identifyer [@V=1234]" test.xml 
<identifyer V="1234"/>

需要两种类型的输出:

$ xmlstarlet <some magic>
<identifyer V="1234"></identifyer>
<property1 V="abcde"></property1>
<Property2 V="qwerty"></property2>

和:

$ xmlstarlet <some magic>
qwerty

请随意编辑标题,我不知道如何最好地表达它:).

我有JSON,例如,看起来像这样:

{
  "things": [
     {
        "name": "foo",
        "params": [
           {
             "type": "t1",
              "key": "key1",
              "value": "val1"
           },
           {
              "type": "t1",
              "key": "category",
              "value": "thefoocategory"
           }
        ]
      },
      {
        "name": "bar",
        "params": [
           {
             "type": "t1",
             "key": "key1",
             "value": "val1"
           },
           {
             "type": "t1",
             "key": "category",
             "value": "thebarcategory"
           }
        ]
     }
  ]
}

我想要实现的是输出看起来像

[
  {
    name: "foo",
    category: "thefoocategory"
  },
  {
    name: "bar",
    category: "thebarcategory"
  }
]

我能够很容易地提取名称 jq ' .things | .[] | .name'

我也可以提取类别 jq ' .things …
