Loops XSLT通过节点循环以获得所需的层次结构
我有一个xml。我想根据Loops XSLT通过节点循环以获得所需的层次结构,loops,xslt,Loops,Xslt,我有一个xml。我想根据BA的值获取的值。我的XSLT正在检索的所有值，如图所示。我希望根据BA获取的值，正如我在所需的XML输出中所示 XML数据：- <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Parent> <parent1 id="parent1_313_1"> <child

我认为我的内部循环没有获取正确的数据。我是XSLT新手。请分享我遗漏的信息。我认为您只需要分组一次：
<?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="#all"
expand-text="yes"
version="3.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="Parent">
<cccs>
<xsl:for-each-group select="parent1/child1" group-by="..//entry[key = 'BA']/value">
<ccc id="BA_{if (current-grouping-key()) then current-grouping-key() else 'unknown'}">
<name>{if (current-grouping-key()) then current-grouping-key() else 'default'}</name>
<cccs>
<xsl:apply-templates select="current-group()"/>
</cccs>
</ccc>
</xsl:for-each-group>
</cccs>
</xsl:template>
<xsl:template match="child1">
<ccc id="BA_{if (current-grouping-key()) then current-grouping-key() else 'unknown'}_{.}">
<name>{.}</name>
</ccc>
</xsl:template>
</xsl:stylesheet>
{if（current-grouping-key（））则current-grouping-key（）否则为“默认值”}
{.}
请用文字解释所需的逻辑。谢谢Martin，这真的很有帮助。我和一个不同的人一起搬家
