带有多条目标记的JSONX到XML示例

首先，我非常感谢，因为这个论坛对学习者真的很有帮助。我再次需要你的帮助

我正在尝试将jsonx转换为常规xml，这里需要做的几件事是

1输出xml应位于提要标记中，如果有多个条目标记进入，则在末尾href link，它应附加条目计数，如下所示

2如果请求中有一个条目，那么我的xml如下所示

3如果授权名称更改为身份验证，则在href链接的末尾，只有最后一部分将更改为身份验证

示例Jsonx附带多个条目标记

这是我的XLST，我不知道如何使用for循环并在末尾将计数附加到href链接

<xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:date="http://exslt.org/dates-and-times"
    xmlns:dp="http://www.datapower.com/extensions" 
    xmlns:dpconfig="http://www.datapower.com/param/config" 
    xmlns:dpfunc="http://www.datapower.com/extensions/functions"
    exclude-result-prefixes="dp" 
    extension-element-prefixes="dp dpconfig dpfunc date">
    <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
    <xsl:template match="/">


        <!-- Generate variables-->
        <xsl:variable name="vCurrentTime" select="date:date-time()"/>
        <xsl:variable name="vRandomSalt" select="dp:generate-uuid()"/>
        <!-- create the AI node -->
        <feed xmlns="http://www.w3.org/2005/Atom" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <id>urn:uuid:<xsl:value-of select="$vRandomSalt"/>
            </id>
            <title>Datausage</title>
            <updated>
                <xsl:value-of select="$vCurrentTime"/>
            </updated>
            <link href="https://services.org/resource/Authorization/Authorization" rel="self"/>
            <xsl:copy-of select="."/> 
        </feed>
    </xsl:template>
</xsl:stylesheet>

首先，您需要执行以下操作，而不是在主模板中使用：

 <xsl:apply-templates />

在本例中，只需跳过它们，选择子json:object，然后在下一个模板中将其转换为条目元素，如下所示：

<xsl:template match="json:array/json:object" priority="2">
    <xsl:element name="{../@name}" namespace="http://www.w3.org/2005/Atom">

        <!-- More code here -->

        <xsl:apply-templates />
    </xsl:element>
</xsl:template>

请注意，此处使用属性值模板来输出数字。大括号表示要计算的表达式，而不是字面上的输出

编辑：要使其依赖于子体对象，它可以如下所示

<link href="https://services.org/resource/{.//json:object[@name='content']/json:object/@name}" rel="up"/>

不过，可能值得先将表达式放在变量中

最后，您将有一个更通用的模板来操作其他json元素

<xsl:template match="json:*[@name]">
    <xsl:element name="{@name}" namespace="http://www.w3.org/2005/Atom">
        <xsl:apply-templates />
    </xsl:element>
 </xsl:template>

请注意，前两个模板被赋予了优先权，以确保它们在这个通用模板之前得到使用

试试这个XSLT

请注意，json的名称空间也必须在XSLT中定义。

非常感谢XSLT。我非常感谢您的帮助…一个快速问题。非常感谢XSLT。我非常感谢您的帮助…一个快速问题。假设如果请求带有Authenticationafter content tag标记，而不是if Authorization，那么我如何更改href的结尾部分，就像我做了一次编辑，表明可以完成一样，如果我理解正确的话！如果没有，它可能会引导您走向正确的方向，至少……如果您遇到XSLT不太有效的情况，最好修改您原来的问题来说明这一点。非常感谢。嘿，蒂姆，我不明白。。。很抱歉
