我需要将顺序
XML节点列表转换为层次结构,但我遇到了一些特定于XSLT的知识差距.
输入XML包含文章,颜色和大小.在下面的示例中,’Record1’是一篇文章,’Record2’代表一种颜色,’Record3’代表大小.颜色和大小(record2和record3)元素的数量可以变化.

<root> <Record1>...</Record1> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record1>...</Record1> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> </root>
所有字段都在相同的层次结构级别,但我仍然需要创建此结构作为输出：
<root> <article> -> Record1 <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> </article> <article> -> Record1 <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> </article> </root>
我已经尝试按顺序迭代节点,但是例如’article'(= record1)节点标签需要保持未闭合,同时处理’color'(= record2)节点.处理’color'(= record3)处理’color’未闭合的计数相同,但XSLT不允许这样做.
我的下一个想法是为每篇文章,颜色和大小级别调用模板,但我不知道如何选择例如当前’record2’和’record1’所代表的下一篇文章之间的所有’record3’节点.
我对XSLT版本也有限制,因为我需要在BizTalk Server中进行这种转换,它只支持XSLT 1.0
有人能把我推向正确的方向吗？
这是一个XSLT 1.0选项.我不确定你想用Record1和Record2的值做什么,所以我把它们放在一个val属性中.

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