xslt 如何将两个 XSLT 合并为一个

Question

我有以下XML。第一个XSLT删除重复记录。第二个XSLT将记录格式化为特定的文件格式。如何将第一个和第二个XSLT合并到一个XSLT中以提供所需的结果?

<XML>
    <Record>
        <GroupId>10028</GroupId>
        <SessionId>264-10028-1-515530-2</SessionId>
        <TxnId>264-10028-1-515539-1</TxnId>
        <Date>31-Jul-2014</Date>
        <Time>11:22:40</Time>
        <Account>1111111111</Account>
        <NAD>5000</NAD>
    </Record>
    <Record>
        <GroupId>10028</GroupId>
        <SessionId>264-10028-1-515530-2</SessionId>
        <TxnId>264-10028-1-515539-2</TxnId>
        <Date>31-Jul-2014</Date>
        <Time>11:22:40</Time>
        <Account>2222222222</Account>
        <NAD>6000</NAD>
    </Record>
    <Record>
        <GroupId>10028</GroupId>
        <SessionId>264-10028-1-515545-1</SessionId>
        <TxnId>264-10028-1-515545-2</TxnId>
        <Date>31-Jul-2014</Date>
        <Time>11:22:55</Time>
        <Account>3333333333</Account>
        <NAD>1000</NAD>
    </Record>
    <Record>
        <GroupId>10028</GroupId>
        <TxnId>264-10028-1-515550-1</TxnId>
        <Date>31-Jul-2014</Date>
        <Time>11:23:32</Time>
        <OrigTxnId>264-10028-1-515545-2</OrigTxnId>
        <Account>3333333333</Account>
        <NAD>1000</NAD>
    </Record>
</XML>

XSLT

第一

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:strip-space elements="*"/>
    <xsl:key name="original" match="Record" use="TxnId" />
    <xsl:key name="copy" match="Record" use="OrigTxnId" />
    <!-- identity transform -->
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="Record[key('original', OrigTxnId) or key('copy', TxnId)]"/>
</xsl:stylesheet>

第二个XSLT:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="no" encoding="iso-8859-1" omit-xml-declaration="yes"/>
    <xsl:template match="/">
        <xsl:for-each select="XML/Record">
            <?Record Type - 1 - Fixed value “D”(etail)?>
            <xsl:text>D</xsl:text>
            <?SeqNo - 6 - Right justified, zero padded?>
            <xsl:value-of select="format-number(count(preceding-sibling::Record)+1, '000000')"/>
            <?CompanyCode - 3 - Leave Blank, Space padded?>
            <xsl:text>&#160;&#160;&#160;</xsl:text>
            <?CustAccountNo - 20 - Right justified, zero padded?>
            <xsl:value-of select="format-number(Account, '00000000000000000000')"/>
            <?NamPostBranch - 50 - ?>
            <xsl:call-template name="reformat-string-length">
                <xsl:with-param name="value" select="GroupId"/>
                <xsl:with-param name="str-len" select="50"/>
            </xsl:call-template>
            <?NamPostReceiptNo - 16 - Group-Node-Sequence No?>
            <xsl:call-template name="reformat-string-length">
                <xsl:with-param name="value" select="substring(TxnId,5,16)"/>
                <xsl:with-param name="str-len" select="16"/>
            </xsl:call-template>                            
            <?MOPCheck?>
            <xsl:choose>
                <xsl:when test="ChequeNo &gt; 0">

Answer 1

在第二个模板中这样定义键:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="no" encoding="iso-8859-1" omit-xml-declaration="yes"/>
    <xsl:key name="original" match="/XML/Record" use="TxnId" />
    <xsl:key name="copy" match="/XML/Record" use="OrigTxnId" />
    <xsl:template match="/">

使用第二个模板的选择器中的键;但是把条件反过来:

    <xsl:template match="/">
        <xsl:for-each select="XML/Record[not(key('original', OrigTxnId) or key('copy', TxnId))]">
