如何解决在xml到json转换中排序和分组
我正在尝试根据“地址”中的“itemLotNo”对订单项进行排序和分组。当 Address 中的 lineitems 相同时，它们应该在方括号或 Array Address[[{...},{...}],[{...}],[{...}]] 之间形成.
数据应该保持不变，即行项目没有变化，只需对相同的“itemLotNo”进行排序和分组。
xml文件：
<root>
<FirstName>Alex</FirstName>
<LastName>Fin</LastName>
<Details>
<Id_Number>111</Id_Number>
<Location>NC</Location>
<Contact>
<PhoneNumber>+1 323</PhoneNumber>
</Contact>
</Details>
<Details>
<Id_Number>222</Id_Number>
<Location>TX</Location>
<Contact>
<PhoneNumber>+1 323</PhoneNumber>
</Contact>
</Details>
<Address>
<itemLotNo>19949-2018-0001-45116-Dot1</itemLotNo>
<Locality>Urban</Locality>
<Type>Mobile</Type>
</Address>
<Address>
<itemLotNo>19950-2018-0001-45116-Dot1</itemLotNo>
<Locality>Rural</Locality>
<Type>Landline</Type>
</Address>
<Address>
<itemLotNo>19949-2018-0001-45116-Dot1</itemLotNo>
<Locality>Rural</Locality>
<Type>Landline</Type>
</Address>
<Address>
<itemLotNo>19958-2018-0001-45116-Dot1</itemLotNo>
<Locality>Rural</Locality>
<Type>Landline</Type>
</Address>
</root>
预期的Json文件：
{
"FirstName": "Alex","LastName": "Fin","Details": [
[
{
"Id_Number": "111","Location": "NC","Contact": {
"PhoneNumber": "+1 323"
}
},{
"Id_Number": "222","Location": "TX","Contact": {
"PhoneNumber": "+1 323"
}
}
]
],"Address": [
[
{
"itemLotNo": "19949-2018-0001-45116-Dot1","Locality": "Urban","Type": "Mobile"
},{
"itemLotNo": "19949-2018-0001-45116-Dot1","Locality": "Rural","Type": "Landline"
}
],[
{
"itemLotNo": "19950-2018-0001-45116-Dot1",[
{
"itemLotNo": "19958-2018-0001-45116-Dot1","Type": "Landline"

解决方法
Address 的特殊处理似乎是您想要的
<xsl:template match="*[*]">
<xsl:param name="key" as="xs:boolean" select="false()"/>
<map>
<xsl:if test="$key">
<xsl:attribute name="key" select="local-name()"/>
</xsl:if>
<xsl:for-each-group select="*" group-by="node-name()">
<xsl:choose>
<xsl:when test="current-group()[2] or self::Details or self::Address">
<array key="{local-name()}">
<xsl:choose>
<xsl:when test="self::Details">
<array>
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="false()"/>
</xsl:apply-templates>
</array>
</xsl:when>
<xsl:when test="self::Address">
<xsl:for-each-group select="current-group()" group-by="itemLotNo">
<array>
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="false()"/>
</xsl:apply-templates>
</array>
</xsl:for-each-group>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="false()"/>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</array>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="true()"/>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</map>
</xsl:template>
如果你把最后一个模板改成这样：
<xsl:template match="*[*]">
<xsl:param name="key" as="xs:boolean" select="false()"/>
<map>
<xsl:if test="$key">
<xsl:attribute name="key" select="local-name()"/>
</xsl:if>
<xsl:for-each-group select="*" group-by="node-name()">
<xsl:choose>
<xsl:when test="current-group()[2] or self::Details or self::Address">
<array key="{local-name()}">
<xsl:choose>
<xsl:when test="self::Details">
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="false()"/>
</xsl:apply-templates>
</xsl:when>
<xsl:when test="self::Address">
<xsl:iterate select="current-group()">
<xsl:apply-templates select="self::Address"/>
</xsl:iterate>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="false()"/>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</array>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()">
<xsl:with-param name="key" select="true()"/>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</map>
</xsl:template>
你会得到这个json：
{
"FirstName": "Alex","LastName": "Fin","Details": [
{
"Id_Number": "111","Location": "NC","Contact": {"PhoneNumber": "+1 323"}
},{
"Id_Number": "222","Location": "TX","Contact": {"PhoneNumber": "+1 323"}
}
],"Address": [
{
"itemLotNo": "19949-2018-0001-45116-Dot1","Locality": "Urban","Type": "Mobile"
},{
"itemLotNo": "19950-2018-0001-45116-Dot1","Locality": "Rural","Type": "Landline"
},{
"itemLotNo": "19949-2018-0001-45116-Dot1",{
"itemLotNo": "19958-2018-0001-45116-Dot1","Type": "Landline"
}
]
}
这与您的 ExpectedJsonFile 不同，因为它没有用于 Address 和 Details 的嵌套数组，但也许它甚至更好。 See json question about array of objects.
