XSLT3 用分隔符连接值 [英] XSLT3 joining values with separator
问题描述
我对 XSLT 还很陌生，我一直在努力复制这里提到的解决方案XSL for-each:如何检测最后一个节点?比我愿意承认的时间更长:(
I'm pretty new to XSLT and I've been struggling to replicate the solution mentioned here XSL for-each: how to detect last node? for longer than I'm willing to admit :(
我已经设置了这个小提琴.https://xsltfiddle.liberty-development.net/naZXVFi
I've setup this fiddle. https://xsltfiddle.liberty-development.net/naZXVFi
我希望我可以只使用 value-of + 分隔符，而不是选择/when xslt 工具，因为它看起来更惯用.
I was hoping I could use just the value-of + separator, vs choose / when xslt tools, as it did seem more idiomatic.
- 我无法显示分隔符；
- 我也不能只选择技能的孩子，我总是也会得到后代.也就是说，我不应该在输出中看到任何
detail. - 奖励:不知道为什么那个元标记没有自动关闭(在 html 部分中发出警告)
所需的输出:skill1、skill2、skill3、skill4、skill5(最后一个没有逗号)
Desired output:
skill1, skill2, skill3, skill4, skill5 (no comma space for the last one)
任何帮助将不胜感激.谢谢.
Any help would be greatly appreciated. Thanks.
也包括此处的代码:xml: (需要给 xslt 添加 ref):
including the code here too: xml: (need to add ref to xslt):
<?xml version="1.0" encoding="utf-8" ?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?> <!-- not in fiddle -->
<skills>
<skill>skill1</skill>
<skill>skill2</skill>
<skill>skill3
<details>
<detail>detail1</detail>
<detail>detail2</detail>
</details>
</skill>
<skill>skill4</skill>
<skill>skill5</skill>
</skills>
和test.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"

xmlns:map="http://www.w3.org/2005/xpath-functions/map"
xmlns:array="http://www.w3.org/2005/xpath-functions/array"
exclude-result-prefixes="#all"
version="3.0">
<xsl:mode on-no-match="shallow-copy"/>
<xsl:output method="html" indent="yes" html-version="5"/>
<xsl:template match="/">
<html>
<head>
<title>.NET XSLT Fiddle Example</title>
</head>
<body>
<xsl:for-each select="/skills/skill">
<xsl:value-of select="." separator=", "/>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
推荐答案
一般来说，使用 XSLT 2/3 来输出由一些分隔符字符串分隔的序列，您只需使用 xsl:value-of select="$sequence" 在 separator 属性中带有适当的分隔符字符串(并且没有 for-each):
In general, with XSLT 2/3 to output a sequence separated by some separator string, you simply use xsl:value-of select="$sequence" with the appropriate separator string in the separator attribute (and no for-each):
<xsl:template match="skills">
<xsl:value-of select="skill/text()[normalize-space()]/normalize-space()" separator=", "/>
</xsl:template>

在大多数情况下，您只需要 select="skill" separator=", " 但考虑到您的后代和空白，您似乎想要消除 select上面的表达式有点复杂.
In most cases you would just need select="skill" separator=", " but given your descendants and the white space you seem to want to eliminate the select expression above is a bit more complicated.
