Question

我是XSLT的新手。使用XSLT将XML转换为JSON时遇到问题。

XML输入

<ArrayOfApiInvoiceReport>
<ApiInvoiceReport>
    <BillingAddress1>9055 LOCUST ST STE B10</BillingAddress1>
    <BillingAddress2/>
    <BillingCity>ELK GROVE</BillingCity>
    <BillingCountry>US</BillingCountry>
    <InvoiceItems>
        <InvoiceItemSizes>
            <InvoiceLineNumber>1</InvoiceLineNumber>
            <InvoicedQuantity>2</InvoicedQuantity>
        </InvoiceItemSizes>
        <InvoiceLineNumber>1</InvoiceLineNumber>
        <InvoiceNumber>101000001</InvoiceNumber>
    </InvoiceItems>
    <InvoiceItems>
        <InvoiceItemSizes>
            <InvoiceLineNumber>2</InvoiceLineNumber>
            <InvoicedQuantity>2</InvoicedQuantity>
        </InvoiceItemSizes>
        <InvoiceLineNumber>2</InvoiceLineNumber>
        <InvoiceNumber>101000001</InvoiceNumber>
    </InvoiceItems>
    <InvoiceNumber>101000001</InvoiceNumber>
    <InvoiceSentDate>20141109</InvoiceSentDate>
    <InvoiceStatus>95</InvoiceStatus>
</ApiInvoiceReport>
<ApiInvoiceReport>
    <BillingAddress1>9055 LOCUST ST STE B10</BillingAddress1>
    <BillingAddress2/>
    <BillingCity>ELK GROVE</BillingCity>
    <BillingCountry>US</BillingCountry>

    <InvoiceItems>
        <InvoiceItemSizes>
            <InvoiceLineNumber>1</InvoiceLineNumber>
            <InvoicedQuantity>2</InvoicedQuantity>
        </InvoiceItemSizes>
        <InvoiceLineNumber>1</InvoiceLineNumber>
        <InvoiceNumber>101000002</InvoiceNumber>
    </InvoiceItems>
    <InvoiceNumber>101000002</InvoiceNumber>
    <InvoiceSentDate>20141109</InvoiceSentDate>
    <InvoiceStatus>95</InvoiceStatus>
</ApiInvoiceReport>
</ArrayOfApiInvoiceReport>

输出JSON

从JSON输出中我们只需要删除ApiInvoiceReport标记。我试图解决这个问题但我做不到。

Answer 1

一个解决方案可能是（不是最优雅的）。改变下一个：

    <xsl:when test="following-sibling::*[1][name() = name(current())]">
        <xsl:text>"</xsl:text>
        <xsl:value-of select="name()"/>
        <xsl:text>" : [</xsl:text>
        <xsl:apply-templates mode="obj-content" select="."/>
        <xsl:text>, </xsl:text>
    </xsl:when>

要：

    <xsl:when test="following-sibling::*[1][name() = name(current())]">
        <xsl:choose>
            <xsl:when test="local-name(current()) = 'ApiInvoiceReport'">
                <xsl:apply-templates mode="detect" select="*"/>
            </xsl:when>
            <xsl:otherwise>
                <xsl:text>"</xsl:text>
                <xsl:value-of select="name()"/>
                <xsl:text>" : [</xsl:text>
                <xsl:apply-templates mode="obj-content" select="."/>
                <xsl:text>, </xsl:text>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:when>
