样式表将XML源文件转换为XML目标格式，同时向目标元素引入前缀

Question

我有这个源xml

<?xml version="1.0" encoding="UTF-8" ?>
<Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<StartOfTransmission>
<SenderId>SENDERSID</SenderId>
<ReceiverId>RECEIVERSID</ReceiverId>
<TRANSDATE>13-09-2010</TRANSDATE>
<TRANSTIME>12:00:00</TRANSTIME>
<SenderReference>1234</SenderReference>
<ReceiverReference/>
<ApplicationReference>ORDHDR</ApplicationReference>
</StartOfTransmission>
</Document>

，我想使用样式表转换将其转换为这种格式。(请注意a:和xmlns:前缀是必需的。)

<?xml version="1.0" encoding="UTF-8"?>
<a:Document xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://127.0.0.1:8080 http://127.0.0.1:8080/test/tbattributesxml2.xsd"
xmlns:a="http://127.0.0.1:8080">
<a:StartOfTransmission SenderId="SENDERSID" ReceiverId="RECEIVERSID" transdatetime="2010-09-13T12:00:00.000" SenderReference="1234" ReceiverReference="" ApplicationReference="ORDHDR"/>
</a:Document>

一旦正确转换，目标xml将通过下面的xsd验证。

<xs:schema  attributeFormDefault="unqualified"
elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://127.0.0.1:8080"
xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
xmlns:w="http://127.0.0.1:8080"
vc:minVersion="1.1" >

<xs:element name="Document">
<xs:complexType>
<xs:sequence>
<xs:element ref="w:StartOfTransmission" minOccurs="1" maxOccurs="1"/>    
</xs:sequence> 
</xs:complexType>
</xs:element>

<xs:element name="StartOfTransmission">
<xs:complexType>
<xs:attribute name="SenderId" use="required">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:minLength value="1"/>
<xs:maxLength value="14"/>
</xs:restriction>

</xs:restriction>
</xs:simpleType>
</xs:attribute>
<xs:attribute name="ReceiverReference" use="optional">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:minLength value="0"/>
<xs:maxLength value="14"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
<xs:attribute name="ApplicationReference" use="required">
<xs:annotation>
<xs:documentation>Value = ORDHDR</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="ORDHDR"/>
<xs:minLength value="1"/>
<xs:maxLength value="14"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
</xs:complexType>
</xs:element>

</xs:schema>

我已经开始这个样式表下面的一半工作(除了冒号丢失)。当我尝试引入a:和xmlns:标记时，它会中断。而且我无法让'xmlns:xsd="http://www.w3.org/2001/XMLSchema"'作为Document元素中的第一个属性出现。一如既往，感谢您的帮助。

Answer 1

AFAICT，您所需要做的就是:

XSLT 2.0

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:a="http://127.0.0.1:8080">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/Document">
<a:Document xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://127.0.0.1:8080 http://127.0.0.1:8080/test/tbattributesxml2.xsd">
<xsl:apply-templates/>
</a:Document>
</xsl:template>     
<xsl:template match="StartOfTransmission">
<a:StartOfTransmission transdatetime="{replace(TRANSDATE, '(.{2})-(.{2})-(.{4})', '$3-$2-$1')}T{TRANSTIME}">
<xsl:apply-templates select="* except(TRANSDATE, TRANSTIME)"/>
</a:StartOfTransmission>
</xsl:template> 

<xsl:template match="StartOfTransmission/*">
<xsl:attribute name="{name()}" select="."/>
</xsl:template>     

</xsl:stylesheet>

注意，这假设TRANSDATE是DD-MM-YYYY格式(即在需要的地方有一个前导零表示day)。
