[英]Merge two XML files with XSLT
我需要合并两个XML文件。
我尝试根据使用XSLT的基于属性值的Merge 2 XML文件中的答案编写XSLT样式表。 ,但我没有成功。
<?xml version="1.0" encoding="UTF-8"?>
<ExtData>
<table bName="B SERs" id="BSER">
<Col bName="Bus" id="BUS">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="Bus" coreId="BUS"/>
</Col>
<Col bName="Ser" id="NAME">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="Ser" coreId="NAME"/>
</Col>
<Col bName="ID" id="ID">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="SerId" coreId="UCMDB_ID"/>
</Col>
</table>
</ExtData>
<?xml version="1.0" encoding="UTF-8"?>
<ExtData>
<table bName="B SERs" id="BSER">
<Col EName="SER" bName="Bus" Id="BUS"/>
<Col EName="SER" bName="Ser" Id="NAME"/>
<Col EName="SER" bName="SerId" Id="DB_ID"/>
<Col EName="SER" bName="SerDate" Id="date"/>
<Col EName="SER" bName="Person" Id="Manager"/>
<Col EName="SER" bName="desc" Id="desc"/>
</table>
</ExtData>
输出需要是:
<?xml version="1.0" encoding="UTF-8"?>
<ExtData>
<table bName="B SERs" id="BSER">
<Col bName="Bus" id="BUS">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="Bus" coreId="BUS"/>
</Col>
<Col bName="Ser" id="NAME">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="Ser" coreId="NAME"/>
</Col>
<Col bName="ID" id="ID">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="SerId" coreId="UCMDB_ID"/>
</Col>
<Col bName="" id="">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="SerDate" coreId="date"/>
</Col>
<Col bName="" id="">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="Person" coreId="Manager"/>
</Col>
<Col bName="" id="">
<CoreCol coreEName="SER" coreHref="../_a2.xml" corebName="desc" coreId="desc"/>
</Col>
</table>
</ExtData>
可以使用XSLT做类似的事情吗?
我敢肯定有更好的方法,但这是我想到的第一个与XSLT 1.0兼容的选项:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- Identity transform -->
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="table">
<xsl:copy>
<xsl:apply-templates select="@* | Col"/>
<!--
Apply <Col> elements in _a2.xml that have a @bName attribute that DOESN'T
have a <CoreCol> element under the current <table> element with a
corresponding @corebName attribute.
-->
<xsl:apply-templates
select="document('_a2.xml')/ExtData/table[@id = current()/@id]
/Col[not(current()/Col/CoreCol/@corebName = @bName)]" mode="merge"/>
</xsl:copy>
</xsl:template>
<xsl:template match="table/@bName">
<xsl:copy/>
</xsl:template>
<!-- Match the elements applied in the template above. -->
<xsl:template match="Col" mode="merge">
<Col bName="" id="">
<CoreCol>
<xsl:apply-templates select="@EName"/>
<xsl:attribute name="coreHref">../_a2.xml</xsl:attribute>
<xsl:apply-templates select="@bName" mode="merge"/>
<xsl:apply-templates select="@Id"/>
</CoreCol>
</Col>
</xsl:template>
<!-- Transform attribute names -->
<xsl:template match="@EName">
<xsl:attribute name="coreEName">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<!--
The @bName attributes in <Col> elements in _a2.xml need to be transformed
into @coreBname elements in the output file. We'll use the "merge" mode so
the @bName attributes in <Col> elements in _a1.xml aren't affected.
-->
<xsl:template match="@bName" mode="merge">
<xsl:attribute name="corebName">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<xsl:template match="@Id">
<xsl:attribute name="coreId">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
