我有一个像这样的输入xml - 

<SAMPLE>
<SAMPLE_ID>111</SAMPLE_ID>
<ROWS>
                    <ROW ROW_TYPE="SPECIFICATION" ROW_ID="1">

                    </ROW>                  
                </ROWS>

我的转换看起来像这样 - 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*"/>
    <xsl:key name="kRowById" match="ROW[not(@ROW_TYPE='SUBTOTAL' or @ROW_TYPE='MAIN' or @ROW_TYPE='COMMENT')]" use="@ROW_ID"/>
    <xsl:template match="ROW[not(@ROW_TYPE='SPECIFICATION')]">
        <xsl:copy-of select="."/>
        <xsl:copy-of select="key('kRowById', @ROW_ID)"/>
    </xsl:template>
    <xsl:template match="text()"/>
</xsl:stylesheet>

我的输出结构正确但唯一的问题是，这个逻辑是在输出xml中添加额外的重复ROWS。 这不是必需的。对此有任何建议。

答案 0 :(得分：0)

因为你的问题只有一个“SAMPLE”元素，所以你想要它看多个“SAMPLE”元素并不完全清楚，但我想你可能需要扩展你的xsl：key来包含SAMPLE_ID元素

<xsl:key name="kRowById" 
         match="ROW[not(@ROW_TYPE='SUBTOTAL' or @ROW_TYPE='MAIN' or @ROW_TYPE='COMMENT')]"
         use="concat(@ROW_ID, '|', ../../SAMPLE_ID)"/>

因此，密钥使用ROW_ID和SAMPLE_ID。注意使用|字符作为分隔符;它可以是任何字符，只要它不出现在ROW_ID或SAMPLE_ID中。

然后，在获取SAMPLE的ROW元素时，在现有xsl：copy中使用相同的键。

<xsl:copy-of select="key('kRowById', concat(@ROW_ID, '|', ../../SAMPLE_ID))"/>

试试这个XSLT 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:key name="kRowById" match="ROW[not(@ROW_TYPE='SUBTOTAL' or @ROW_TYPE='MAIN' or @ROW_TYPE='COMMENT')]" use="concat(@ROW_ID, '|', ../../SAMPLE_ID)"/>

    <xsl:template match="ROW[not(@ROW_TYPE='SPECIFICATION')]">
        <xsl:copy-of select="."/>
        <xsl:copy-of select="key('kRowById', concat(@ROW_ID, '|', ../../SAMPLE_ID))"/>
    </xsl:template>

    <xsl:template match="text()"/>

    <xsl:template match="SAMPLE">
      <xsl:copy>
        <xsl:apply-templates />
      </xsl:copy>
    </xsl:template>
</xsl:stylesheet>
