Question

我一直在尝试编写一个xslt转换，将'俄罗斯娃娃'风格的xsd转换为'百叶帘'。

我写了一些东西，但这并不像我想的那样完全奏效。所以我有以下xsd文件：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="GX" targetNamespace="GX" elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:complexType name="topType">
        <xs:sequence>
            <xs:element name="REQUESTOR" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
            <xs:element name="RETURN_CANCELLED_CUSTOMERS" nillable="false" minOccurs="0" maxOccurs="1">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="EXTERNAL_CUSTOMER_ID" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
                        <xs:element name="ON_BEHALF_OF" type="xs:string" nillable="false" minOccurs="1" maxOccurs="1"/>
                        <xs:element name="MSISDN_aaa" nillable="false" minOccurs="0" maxOccurs="1">
                            <xs:complexType>

                                    <xs:element name="GSP_ID" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
                                    <xs:element name="MSISDN_bbb" nillable="false" minOccurs="0" maxOccurs="1">

                                                <xs:element name="MSISDN_ccc" nillable="false" minOccurs="0" maxOccurs="1">
                                                    <xs:complexType>
                                                        <xs:sequence>
                                                            <xs:element name="SSPC_ID" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
                                                            <xs:element name="MSISDN_ddd" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
                                                            <xs:element name="IMSI" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
                                                            <xs:element name="MSISDN" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>
                                                        </xs:sequence>
                                                    </xs:complexType>
                                                </xs:element>
                                            </xs:sequence>
                                        </xs:complexType>
                                    </xs:element>
                                </xs:sequence>
                            </xs:complexType>
                        </xs:element>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:schema>

我尝试转换为：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="GX" targetNamespace="GX" elementFormDefault="qualified" attributeFormDefault="unqualified">

            <xs:element name="RETURN_CANCELLED_CUSTOMERS" type="tns:RETURN_CANCELLED_CUSTOMERSType" nillable="false" minOccurs="0" maxOccurs="1"/>
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="RETURN_CANCELLED_CUSTOMERSType">
        <xs:sequence>
            <xs:element name="EXTERNAL_CUSTOMER_ID" type="xs:string" nillable="false" minOccurs="0" maxOccurs="1"/>

        </xs:sequence>
    </xs:complexType>
</xs:schema>

我写的XSLT正在进行中，我正在努力......有没有人做过类似的事情，可以提供一些建议？基本上我被卡住了。

    </xsl:template>
    <!--find the most nested complex type i.e. there are no more child complext types-->
    <xsl:template match="xs:complexType[not(xs:sequence/xs:element/xs:complexType)]">
        <xs:complexType name="{../@name}Type">
            <xsl:copy-of select="child::node()"/>
            <xs:element>current:<xsl:value-of select="./@name"/> parent: <xsl:value-of select="../@name"/>NO MORE NESTING!!!!!!!!!!!!!</xs:element>
        </xs:complexType>
    </xsl:template>
    <xsl:template match="xs:element">
        <xsl:copy>
            <xsl:apply-templates select="attribute()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="attribute()">
        <xsl:copy/>
    </xsl:template>
    <xsl:template match="xs:element[xs:complexType]">
        <xs:element name="{@name}" type="{@name}Type" nillable="{@nillable}" minOccurs="{@minOccurs}" maxOccurs="{@maxOccurs}"/>
        <xsl:apply-templates/>
    </xsl:template>
</xsl:stylesheet>

Answer 1

您可以在根模板中开始，只需在xsd中选择所有复杂类型

<xsl:apply-templates select="//xs:complexType" />

然后，您将拥有一个模板来匹配没有名称的复杂类型，因此您可以使用基于其父元素的名称输出它们。

<xsl:template match="xs:complexType[not(@name)]">
    <xs:complexType name="{../@name}Type">
        <xsl:apply-templates/>
    </xs:complexType>
</xsl:template>

最后，您将拥有一个模板来匹配具有复杂类型的元素，并添加一个类型属性

<xsl:template match="xs:element[xs:complexType]">
    <xs:element type="{@name}Type">
        <xsl:apply-templates select="@*" />
    </xs:element>
</xsl:template>

这是完整的XSLT

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:exsl="http://exslt.org/common" exclude-result-prefixes='exsl'>
  <xsl:output method="xml" indent="yes"/>
  <xsl:template match="/">
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="GX" targetNamespace="GX" elementFormDefault="qualified" attributeFormDefault="unqualified">
      <!-- processing starts here from the root element -->
      <xsl:apply-templates select="//xs:complexType" />
    </xs:schema>
  </xsl:template>

  <xsl:template match="xs:complexType[not(@name)]">
    <xs:complexType name="{../@name}Type">
      <xsl:apply-templates/>
    </xs:complexType>
  </xsl:template>

  <xsl:template match="xs:element[xs:complexType]">
    <xs:element type="{@name}Type">
      <xsl:apply-templates select="@*" />
    </xs:element>
  </xsl:template>

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()" />
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

当应用于XSD XML时，输出以下内容

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:tns="GX"
           targetNamespace="GX"
           elementFormDefault="qualified"
           attributeFormDefault="unqualified">
  <xs:complexType name="topType">
    <xs:sequence>
      <xs:element maxOccurs="1" minOccurs="0" name="REQUESTOR" nillable="false" type="xs:string"/>
      <xs:element type="RETURN_CANCELLED_CUSTOMERSType" maxOccurs="1" minOccurs="0" name="RETURN_CANCELLED_CUSTOMERS" nillable="false"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="RETURN_CANCELLED_CUSTOMERSType">
    <xs:sequence>
      <xs:element maxOccurs="1" minOccurs="0" name="EXTERNAL_CUSTOMER_ID" nillable="false" type="xs:string"/>
      <xs:element maxOccurs="1" minOccurs="1" name="ON_BEHALF_OF" nillable="false" type="xs:string"/>
      <xs:element type="MSISDN_aaaType" maxOccurs="1" minOccurs="0" name="MSISDN_aaa" nillable="false"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="MSISDN_aaaType">
    <xs:sequence>
      <xs:element maxOccurs="1" minOccurs="0" name="GSP_ID" nillable="false" type="xs:string"/>
      <xs:element type="MSISDN_bbbType" maxOccurs="1" minOccurs="0" name="MSISDN_bbb" nillable="false"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="MSISDN_bbbType">
    <xs:sequence>
      <xs:element maxOccurs="1" minOccurs="0" name="SSPP_ID" nillable="false" type="xs:string"/>
      <xs:element type="MSISDN_cccType" maxOccurs="1" minOccurs="0" name="MSISDN_ccc" nillable="false"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="MSISDN_cccType">
    <xs:sequence>
      <xs:element maxOccurs="1" minOccurs="0" name="SSPC_ID" nillable="false" type="xs:string"/>
      <xs:element maxOccurs="1" minOccurs="0" name="MSISDN_ddd" nillable="false" type="xs:string"/>
      <xs:element maxOccurs="1" minOccurs="0" name="IMSI" nillable="false" type="xs:string"/>
      <xs:element maxOccurs="1" minOccurs="0" name="MSISDN" nillable="false" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>
