如何在 xsl 转换中将多个属性从源映射到目标上的多值属性 [英] How to map multiple attributes from source to a multivalued attribute on target in xsl transformations

问题描述

我必须使用 xsl 转换来从一个 wsdl 映射到另一个.在我的源 wsdl 中，我有一个具有多个值的属性，例如源 wsdl 的结果是

I have to use xsl transformations for mapping from one wsdl to another.In my source wsdl I have an attribute which has multiple values for example the result from the sorce wsdl is

<Groups>
<group>Group1</group>
<group>Group2</group>
</Groups>

在目标 wsdl 中 this 要映射到的属性的类型是:

The type of the attribute to which this is to be mapped in the target wsdl is :

    <xs:complexType name="attributesMultiValued">
    <xs:sequence>
      <xs:element name="name" type="xs:string" minOccurs="0"/>
      <xs:element name="values" type="xs:string"
                  nillable="true" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>

我尝试使用简单的 for-each，但这并没有得到值.

I tried with simple for-each, but this is not getting the values.

示例转换代码:

<attributesMultiValued>
  <name>
    <xsl:text disable-output-escaping="no">Groups</xsl:text>
  </name>
  <xsl:for-each select="tns:Groups">
    <values>
      <xsl:value-of select="group"/>
    </values>
  </xsl:for-each>
</attributesMultiValued>

如何获取values中的所有group?

推荐答案

看起来这就是您要执行的操作:

It looks like this is what you're trying to do:

<attributesMultiValued>
  <name>Groups</name>
  <xsl:for-each select="tns:Groups/tns:Group">
    <values>
      <xsl:value-of select="." />
    </values>
  </xsl:for-each>
</attributesMultiValued>

更好的方法是使用模板:

A better approach is to use templates:

<attributesMultiValued>
  <name>Groups</name>
  <xsl:apply-templates select="tns:Groups/tns:Group" />
</attributesMultiValued>

<!-- A bit further down... -->
<xsl:template match="tns:Group">
  <values>
    <xsl:value-of select="." />
  </values>
</xsl:template>    

但是，如果没有更广泛的 XML 示例(例如，tns: 命名空间来自何处?未显示在您的示例 XML 中.

However, I can't be sure that either of these is what you need without a more extensive example of your XML (for example, where is the tns: namespace coming from? It's not shown in your example XML.
