使用XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0">
<xsl:output method="xml"/>
<xsl:template match="/">
<records>
<record>
<!-- Group record by bigID, for further processing -->
<xsl:for-each-group select="records/record" group-by="bigID">
<xsl:sort select="bigID"/>
<xsl:for-each select="current-group()">
<!-- Create new combined record -->
<bigID>
<!-- <xsl:value-of select="."/> -->
<xsl:for-each select=".">
<xsl:value-of select="bigID"/>
</xsl:for-each>
</bigID>
<text>
<xsl:value-of select="text"/>
</text>
</xsl:for-each>
</xsl:for-each-group>
</record>
</records>
</xsl:template>
</xsl:stylesheet>
我想改变:
<?xml version="1.0" encoding="UTF-8"?>
<records>
<record>
<bigID>123</bigID>
<text>Contains text for 123</text>
<bigID>456</bigID>
<text>Some 456 text</text>
<bigID>123</bigID>
<text>More 123 text</text>
<bigID>123</bigID>
<text>Yet more 123 text</text>
</record>
</records>
成:
<?xml version="1.0" encoding="UTF-8"?>
<records>
<record>
<bigID>123
<text>Contains text for 123</text>
<text>More 123 text</text>
<text>Yet more 123 text</text>
</bigID>
<bigID>456
<text>Some 456 text</text>
</bigID>
</record>
</records>
现在,我只是单独列出分组<bigID
&gt; s。我错过了分组后的步骤,我将分组<bigID
&gt;组合在一起。节点。我怀疑是我需要以某种方式使用“密钥”功能,但我不确定。
感谢您的帮助。

以下是想要的XSLT 2.0转换:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:key name="kTextforId" match="text"
use="preceding-sibling::bigID[1]"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="record">
<record>
<xsl:for-each-group select="bigID" group-by=".">
<bigID>
<xsl:sequence select="current-grouping-key()"/>
<xsl:copy-of select=
"key('kTextforId', current-grouping-key())"/>
</bigID>
</xsl:for-each-group>
</record>
</xsl:template>
</xsl:stylesheet>
在提供的XML文档上执行时,会生成所需的结果。

在XSLT 2.0中,您不需要用于分组的键。
由于您只是复制组中的text
元素,因此可以删除内部for-each。
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<records>
<record>
<xsl:for-each-group select="records/record/bigID" group-by=".">
<xsl:sort select="." data-type="number" />
<bigID>
<xsl:value-of select="." />
<xsl:copy-of select="current-group()/following-sibling::text[1]" />
</bigID>
</xsl:for-each-group>
</record>
</records>
</xsl:template>
</xsl:stylesheet>
如果您想要输出bigID
元素后跟其文本元素,那么我的循环将替换为以下内容。
<xsl:for-each-group select="records/record/bigID" group-by=".">
<xsl:sort select="." data-type="number" />
<xsl:copy-of select="." />
<xsl:copy-of select="current-group()/following-sibling::text[1]" />
</xsl:for-each-group>
