我有一个源 xml，其中包含现场地址，需要转换为一个 xml，将所有地址保存到单个元素中并引用每个地址。
我正在使用 Saxon 9.1 处理器和样式表版本 1.0。
感谢您的帮助。
源代码：
<?xml version="1.0" encoding="utf-8"?>
<ContactDetails xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<AddressDetails StartDate="1992-04-03" Type="Previous">
<Address>
<City City="Wien" />
<Postcode Postcode="LSP-123" />
</Address>
</AddressDetails>
<AddressDetails StartDate="1982-09-19" Type="Current">
<Address>
<City City="Toronto" />
<Postcode Postcode="LKT-947" />
</Address>
</AddressDetails>
<AddressDetails StartDate="1977-05-27" Type="Mailing">
<Address>
<City City="Sydney" />
<Postcode Postcode="OKU-846" />
</Address>
</AddressDetails>
</ContactDetails>
目标代码：
<?xml version="1.0" encoding="utf-8"?>
<Application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ContactDetails>
<AddressDetails StartDate="1992-04-03" Type="Previous">
<AddressRef ReferedID="Prev_1" />
</AddressDetails>
<AddressDetails StartDate="1982-09-19" Type="Current">
<AddressRef ReferedID="Curr_2" />
</AddressDetails>
<AddressDetails StartDate="1977-05-27" Type="Mailing">
<AddressRef ReferedID="Mail_3" />
</AddressDetails>
</ContactDetails>
<AddressSegment>
<Address>
<ID ID="Prev_1" />
<City City="Wien" />
<Postcode Postcode="LSP-123" />
</Address>
<Address>
<ID UniqueID="Curr_2" />
<City City="Toronto" />
<Postcode Postcode="LKT-947" />
</Address>
<Address>
<ID UniqueID="Mail_3" />
<City City="Sydney" />
<Postcode Postcode="OKU-846" />
</Address>
</AddressSegment>
</Application>
当我尝试先生成 ID 并将其复制到地址中时，我使用了 key 和generate-id。这是我对 xslt 的最后一次尝试（我得到的最好结果是 UniqueID 为空，所以我不知道这个解决方案还有多远:)）
<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="ID_key" match="*[@ReferedID]" use="@ReferedID"/>
<xsl:template match="/">
<Application>
<ContactDetails>
<xsl:for-each select="Application/Person/ContactDetails/AddressDetails">
<AddressDetails>
<xsl:attribute name="StartDate">
<xsl:value-of select="@StartDate"/>
</xsl:attribute>
<xsl:attribute name="Type">
<xsl:value-of select="@Type" />
</xsl:attribute>
<AddressRef>
<xsl:attribute name="ReferedID">
<xsl:value-of select="generate-id()"/>
</xsl:attribute>
</AddressRef>
</AddressDetails>
</xsl:for-each>
</ContactDetails>
<AddressSegment>
<xsl:for-each select="Application/Person/ContactDetails/AddressDetails">
<Address>
<ID>
<xsl:attribute name="UniqueID">
<xsl:value-of select="Address/ID[generate-id()=generate-id(key('ID_key',@UniqueID))]" />
</xsl:attribute>
</ID>
<City>
<xsl:attribute name="City">
<xsl:value-of select="Address/City/@City"/>
</xsl:attribute>
</City>
<Postcode>
<sl:attribute name="Postcode">
<xsl:value-of select="Address/Postcode/@Postcode"/>
</xsl:attribute>
</Postcode>
</Address>
</xsl:for-each>
</AddressSegment>
</Application>
</xsl:template>
</xsl:stylesheet>
为了给您提供如何使用generate-id和模式的示例，示例样式表
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:strip-space elements="*"/>
<xsl:output indent="yes"/>
<xsl:template match="ContactDetails">
<xsl:copy>
<xsl:copy-of select="@*"/>
<ContactDetails>
<xsl:apply-templates select="AddressDetails/Address" mode="det"/>
</ContactDetails>
<AddressSegment>
<xsl:apply-templates select="AddressDetails/Address"/>
</AddressSegment>
</xsl:copy>
</xsl:template>
<xsl:template match="Address" mode="det">
<AddressDetails StartDate="{../@StartDate}" Type="{../@Type}">
<AddressRef ReferedID="{generate-id()}"/>
</AddressDetails>
</xsl:template>
<xsl:template match="Address">
<xsl:copy>
<xsl:copy-of select="@*"/>
<ID ID="{generate-id()}"/>
<xsl:copy-of select="*"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
转换输入
<?xml version="1.0" encoding="utf-8"?>
<ContactDetails xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<AddressDetails StartDate="1992-04-03" Type="Previous">
<Address>
<City City="Wien" />
<Postcode Postcode="LSP-123" />
</Address>
</AddressDetails>
<AddressDetails StartDate="1982-09-19" Type="Current">
<Address>
<City City="Toronto" />
<Postcode Postcode="LKT-947" />
</Address>
</AddressDetails>
<AddressDetails StartDate="1977-05-27" Type="Mailing">
<Address>
<City City="Sydney" />
<Postcode Postcode="OKU-846" />
</Address>
</AddressDetails>
</ContactDetails>
将 Saxon 6.5.5 输入到输出中
<ContactDetails xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ContactDetails>
<AddressDetails StartDate="1992-04-03" Type="Previous">
<AddressRef ReferedID="d0e3"/>
</AddressDetails>
<AddressDetails StartDate="1982-09-19" Type="Current">
<AddressRef ReferedID="d0e7"/>
</AddressDetails>
<AddressDetails StartDate="1977-05-27" Type="Mailing">
<AddressRef ReferedID="d0e11"/>
</AddressDetails>
</ContactDetails>
<AddressSegment>
<Address>
<ID ID="d0e3"/>
<City City="Wien"/>
<Postcode Postcode="LSP-123"/>
</Address>
<Address>
<ID ID="d0e7"/>
<City City="Toronto"/>
<Postcode Postcode="LKT-947"/>
</Address>
<Address>
<ID ID="d0e11"/>
<City City="Sydney"/>
<Postcode Postcode="OKU-846"/>
</Address>
</AddressSegment>
</ContactDetails>
