我希望通过查看 XSLT 是否可以为每个匹配项增加文本编号来缩短我的 XSLT 代码库。文本编号存在于属性值“label-period0”和“xls:value-of”值中。
代码有效,没有错误,所以这更多的是如何缩短代码并利用字符串中特定字符的某种迭代的问题。
我为“period0”和“period1”添加了 2 个类似的代码结构,以更好地查看文本字符串中数字方面所需的确切更改。
源 XML 文件:
<data>
<periods>
<period0><from>2016-01-01</from><to>2016-12-01</to></period0>
<period1><from>2015-01-01</from><to>2015-12-01</to></period1>
<period2><from>2014-01-01</from><to>2014-12-01</to></period2>
<period3><from>2013-01-01</from><to>2013-12-01</to></period3>
</periods>
<balances>
<balance0><instant>2016-12-31</instant></balance0>
<balance1><instant>2015-12-31</instant></balance1>
<balance2><instant>2014-12-31</instant></balance2>
<balance3><instant>2013-12-31</instant></balance3>
</balances>
</data>
XSL 文件:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:transform
version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output method="xml" indent="yes"/>
<!-- Block all data that has no user defined template -->
<xsl:mode on-no-match="shallow-skip"/>
<xsl:template match="data">
<results>
<periods>
<periods label="period0">
<xsl:value-of
select =
"concat(periods/period0/from, '--', periods/period0/to)"
/>
</periods>
<periods label="period1">
<xsl:value-of
select =
"concat(periods/period1/from, '--', periods/period1/to)"
/>
</periods>
<!-- Etc for period [2 and 3]-->
</periods>
<balances>
<balance label="balance0">
<xsl:value-of select ="balances/balance0/instant"/>
</balance>
<!-- Etc for balance [1,2 and 3] -->
</balances>
</results>
</xsl:template>
</xsl:transform>
结果:
<?xml version="1.0" encoding="UTF-8"?>
<results>
<periods>
<periods label="period0">2016-01-01--2016-12-01</periods>
<periods label="period1">2015-01-01--2015-12-01</periods>
</periods>
<balances>
<balance label="balance0">2016-12-31</balance>
</balances>
</results>
想要的结果:
(使用 XSL 对文本字符串中的数字进行步进,或 XSL 中可以满足操作文本字符串中数字的任何其他逻辑)
<?xml version="1.0" encoding="UTF-8"?>
<results>
<periods>
<periods label="period0">2016-01-01--2016-12-01</periods>
<periods label="period1">2015-01-01--2015-12-01</periods>
<periods label="period2">2014-01-01--2015-12-01</periods>
<periods label="period3">2013-01-01--2015-12-01</periods>
</periods>
<balances>
<balance label="balance0">2016-12-31</balance>
<balance label="balance1">2015-12-31</balance>
<balance label="balance2">2014-12-31</balance>
<balance label="balance3">2013-12-31</balance>
</balances>
</results>
