如何在xslt中将特定节点作为列表，我希望在json中输出

Question

我有xml，我希望使用xslt将其输出为json。我发现它的solution，但我需要一些改变，我无法做到这一点因为我是xslt的新手。在这个解决方案中我想要一些嵌套标签作为json中的列表，但是这个解决方案将xml中的所有嵌套标签作为json中的列表给出了我不想要的。重点是我要删除额外的[]。请帮帮我

我的xml是

<?xml version="1.0" encoding="UTF-8"?><User>
<MaritalStatus>Single</MaritalStatus>
<Name>
    <FirstName>abc</FirstName>
    <MiddleName>def</MiddleName>
    <LastName>ghi</LastName>
</Name>
<Relative>
    <Father>
        <Name>
            <FirstName>abc</FirstName>
            <MiddleName>def</MiddleName>
            <LastName>ghi</LastName>
        </Name>
    </Father>
    <Mother>
        <Name>
            <FirstName>abc</FirstName>
            <MiddleName>def</MiddleName>
            <LastName>ghi</LastName>
        </Name>
    </Mother>
    <Sibling>
        <Name>
            <FirstName>abc</FirstName>
            <MiddleName>def</MiddleName>
            <LastName>ghi</LastName>
        </Name>

    </Sibling>
</Relative>
<Friend>
    <Name>
        <FirstName>abc</FirstName>
        <MiddleName>def</MiddleName>
        <LastName>ghi</LastName>
    </Name>
</Friend></User>

给我的解决方案我提到的是给我json

[{
"MaritalStatus": "Single",
"Name": [
  {
    "FirstName": "abc",
    "MiddleName": "def",
    "LastName": "ghi"
  }
],
"Relative": [
  {
    "Father": [
      {
        "Name": [
          {
            "FirstName": "abc",
            "MiddleName": "def",
            "LastName": "ghi"
          }
        ]
      }
    ],
    "Mother": [
      {
        "Name": [
          {
            "FirstName": "abc",
            "MiddleName": "def",
            "LastName": "ghi"
          }
        ]
      }
    ],
    "Sibling": [
      {
        "Name": [
          {
            "FirstName": "ewqrew",
            "MiddleName": "defasdfadsf",
            "LastName": "ghiqwerwqer"
          }
        ]
      }
    ]
  }
],
"Friend": [
  {
    "Name": [
      {
        "FirstName": "asd",
        "MiddleName": "ghd",
        "LastName": "rtu"
      }
    ]
  }
]}]

但我想要的输出是

{
"MaritalStatus": "Single",
"Name":
  {
    "FirstName": "abc",
    "MiddleName": "def",
    "LastName": "ghi"
  },
"Relative": [
  {
    "Father":
      {
        "Name":
          {
            "FirstName": "abc",
            "MiddleName": "def",
            "LastName": "ghi"
          }
      },
    "Mother":
      {
        "Name":
          {
            "FirstName": "abc",
            "MiddleName": "def",
            "LastName": "ghi"
          }
      },
    "Sibling": [
      {
        "Name":
          {
            "FirstName": "ewqrew",
            "MiddleName": "defasdfadsf",
            "LastName": "ghiqwerwqer"
          }
      }
    ]
  }
],
"Friend": [
  {
    "Name": 
      {
        "FirstName": "asd",
        "MiddleName": "ghd",
        "LastName": "rtu"
      }
  }
]}

使用Saxon Home您可以利用XPath 3.1功能fn:xml-to-json。我将提供一个非常简单的解决方案，以便了解这个问题。

下载Saxon Home并在下面创建xslt（test.xsl）。跑

java -jar Saxon-HE-9.7.0-7.jar -s:<your-xml-file> -xsl:test.xsl

（用您下载的版本替换Saxon jar文件名）

test.xsl

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fn="http://www.w3.org/2005/xpath-functions">
    <xsl:output method="text" encoding="UTF-8" indent="yes" />

    <!-- Naive approach -->
    <xsl:template match="/">
        <xsl:variable name="xmljson">
            <xsl:apply-templates />
        </xsl:variable>
        <xsl:value-of select="fn:xml-to-json($xmljson)" />
    </xsl:template>

    <xsl:template match="User">
        <fn:map>
            <xsl:apply-templates />
        </fn:map>
    </xsl:template>

    <xsl:template match="MaritalStatus">
        <fn:string key="MaritalStatus">
            <xsl:value-of select="." />
        </fn:string>
    </xsl:template>

    <xsl:template match="Name">
        <fn:map key="Name">
            <xsl:apply-templates />
        </fn:map>
    </xsl:template>

    <xsl:template match="FirstName">
        <fn:string key="FirstName">
            <xsl:value-of select="." />
        </fn:string>
    </xsl:template>

    <!-- TODO (naive approach)-->
    <xsl:template match="Relative" />
    <xsl:template match="Friend" />
    <xsl:template match="MiddleName" />
    <xsl:template match="LastName" />

    <!-- TODO better way: fiddle with copy local-name() and more -->

</xsl:stylesheet>
