Question

你能帮我用xslt将xml转换成另一种格式吗？我有一个输入XML需要转换为另一种格式，但我尝试使用XSLT，但徒劳无功。请提供示例代码。

这是源XML

在XSL转换后

名称2而不是名称1，名称3而不是名称1。 15而不是388061,1569而不是388061。

我应该在XSL中更改以获得正确的结果？提前谢谢。

Answer 1

xsl:value-of中的两个表达式以/ns0:Messages/开头，这意味着他们将从文档节点开始选择，最终将选择它在文档中找到的第一个值，无论您在何处地定位。

将xsl:for-each更改为此，其中包含相对于当前Product节点的表达式。

<xsl:for-each select="$valueFromSource">
    <Products>
        <IdOrigin>SAP_ERP_MATNR</IdOrigin>
        <Id><xsl:value-of select="Values/Value[@AttributeID='atr_ext_ar_nr']"/></Id>
        <Name><xsl:value-of select="Values/Value[@AttributeID='atr_pt_calc']"/></Name>
        <Description><xsl:value-of select="Values/Value[@AttributeID='atr_pt_calc']"/></Description>
    </Products>
</xsl:for-each>

获取XML并转换为具有上下文更改的另一种xml格式
