wso2 将 xml 转换为 json 与数组

Question

I am trying to convert xml to json using an xslt. When I have single node, the JSON output does not contain an array, but when it has multiple nodes it will show up as an array

If I have single Report Entry then JSON output is as follows (missing the array):

XML:

<Report_Data>
    <Report_Entry>
        <ID>0025440</ID>
    </Report_Entry>
</Report_Data>

Results:

{
    "Report_Data": {
        "Report_Entry": 
            {  "ID": "0025440" }
    }
}

When I have multiple entry in XML then the output is as follows (array exists):

XML:

<Report_Data>
    <Report_Entry>
        <ID>0025440</ID>
    </Report_Entry>
    <Report_Entry>
        <ID>00254401</ID>
    </Report_Entry>
</Report_Data>

Results:

{
    "Report_Data": {
        "Report_Entry": [
            { "ID": "0025440" },
            { "ID": "0025441" }
        ]
    }
}

This is a sample Input XML File Trying to Add Arrays in WSo2. This fails to add arays in JSON output.

 <xyz:AStatus xyz:Descriptor="Pending"> <xyz:ID xyz:type="ID">5e3ae98c7e4b4af9836cd</xyz:ID> <xyz:ID xyz:type="DID">PENDING</xyz:ID> </xyz:AStatus> <xyz:Net>0</xyz:Net> <xyz:AMoment>2019-10-10</xyz:AMoment> </xyz:Report_Entry> </xyz:Report_Data> </env:Body> </env:Envelope> </xyz:Body> </xyz:Envelope>

This is formatted properly with out any issues since it has multiple Report Entrys:

Answer 1

If you want to present 'Report_Entry' as a JSON array, regardless of it has one or many elements, this needs to be done inside the XSLT file and need to include below XML processing instruction.

<xsl:processing-instruction name="xml-multiple">Report_Entry</xsl:processing-instruction>

Answer 2

You can try this:

    <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="xs"
    version="2.0">
    <xsl:output method="text" omit-xml-declaration="yes" indent="yes"/>
    <xsl:template match="Report_Data">
        <xsl:text>{</xsl:text>
        <xsl:text>&#x0A;</xsl:text>
        <xsl:text>&#x2003;"</xsl:text><xsl:value-of select="local-name()"/><xsl:text>":</xsl:text>
        <xsl:for-each select="Report_Entry">
            <xsl:text>{</xsl:text><xsl:text>&#x0A;</xsl:text>
            <xsl:text>&#x2003;&#x2003;"</xsl:text><xsl:value-of select="local-name()"/><xsl:text>":</xsl:text>
            <xsl:for-each select="ID">
                <xsl:if test="following-sibling::* and position()=1">[&#x0A;</xsl:if>
                <xsl:if test="not(following-sibling::*) and position()=1"><xsl:text>&#x0A;</xsl:text></xsl:if>
                <xsl:text>&#x2003;&#x2003;&#x2003;{</xsl:text><xsl:text>"</xsl:text><xsl:value-of select="local-name()"/><xsl:text>": </xsl:text><xsl:value-of select="concat('&quot;',.,'&quot;')"/><xsl:text>}</xsl:text><xsl:text>&#x0A;</xsl:text>
                <xsl:if test="preceding-sibling::* and position()=last()">&#x2003;&#x2003;]&#x0A;</xsl:if>
            </xsl:for-each>
            <xsl:text>&#x2003;}</xsl:text><xsl:text>&#x0A;</xsl:text>
        </xsl:for-each>
        <xsl:text>}</xsl:text>
    </xsl:template>
</xsl:stylesheet>
