Regex XSLT2.0:创建正则表达式从连续文本节点枚举章节号和描述
我喜欢将章节号、标题和描述从XML文件提取到XML元素/属性层次结构。它们分布在不同元素的连续文本中。XML如下所示:Regex XSLT2.0:创建正则表达式从连续文本节点枚举章节号和描述,regex,xml,xslt-2.0,Regex,Xml,Xslt 2.0,我喜欢将章节号、标题和描述从XML文件提取到XML元素/属性层次结构。它们分布在不同元素的连续文本中。XML如下所示: <?xml version="1.0" encoding="utf-8"?> <root> <cell>3.1.1.17 First Section The “First appropriate” section lists things that can occur when an event happens.

3.1.1.17第一节“第一适当”节列出了事件发生时可能发生的事情。所有这些事件条件都会导致错误。

到目前为止,我的XSLT是:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" method="xml" encoding="utf-8" />
<xsl:template match="text()" />
<xsl:template match="/root">
<Root>
<xsl:apply-templates select="cell" />
</Root>
</xsl:template>
<xsl:template match="cell">
<xsl:variable name="sections" as="element(Desc)*">
<xsl:analyze-string regex="(\d+\.\d+\.\d+\.\d+)\s(.*?Section)(.*?)" select="text()">
<xsl:matching-substring>
<Desc chapter="{regex-group(1)}" title="{regex-group(2)}">
<xsl:value-of select="regex-group(3)" />
</Desc>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:variable>
<xsl:for-each select="$sections">
<xsl:copy-of select="." />
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
问题位于正则表达式的最后一部分:(.*)
——一个非贪婪的消费表达式。不幸的是,我不能让它停在正确的位置。我试图使用?:
和(?=…)
使其在下一次\d+\.\d+\.\d+\.\d+\.
之前停止非消费,但XSLT-2.0的正则表达式语法似乎与其他方言有所不同
我如何提取相关部分,以便在中为每个作为regex组(1..3)
方便地处理它们
此外,我还对所有正则表达式标记的一个相当完整的XSLT-2.0引用感兴趣。
<xsl:template match="cell">
<xsl:variable name="sections">
<xsl:analyze-string regex="(\d+\.\d+\.\d+\.\d+)\s(.*?Section)" select=".">
<xsl:matching-substring>
<xsl:message select="concat('|', regex-group(3), '|')"/>
<Desc chapter="{regex-group(1)}" title="{regex-group(2)}">
<xsl:value-of select="regex-group(3)" />
</Desc>
</xsl:matching-substring>
<xsl:non-matching-substring>
<Value>
<xsl:value-of select="."/>
</Value>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:variable>
<xsl:for-each select="$sections/Desc">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:value-of select="following-sibling::Value[1]"/>
</xsl:copy>
</xsl:for-each>
</xsl:template>
捕获要选择的数据和尾随文本。看起来
<xsl:template match="cell">
<xsl:variable name="sections">
<xsl:analyze-string regex="(\d+\.\d+\.\d+\.\d+)\s(.*?Section)" select=".">
<xsl:matching-substring>
<xsl:message select="concat('|', regex-group(3), '|')"/>
<Desc chapter="{regex-group(1)}" title="{regex-group(2)}">
<xsl:value-of select="regex-group(3)" />
</Desc>
</xsl:matching-substring>
<xsl:non-matching-substring>
<Value>
<xsl:value-of select="."/>
</Value>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:variable>
<xsl:for-each select="$sections/Desc">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:value-of select="following-sibling::Value[1]"/>
</xsl:copy>
</xsl:for-each>
</xsl:template>
捕获您要选择的数据和尾随文本。很抱歉,我必须用JS回复,但我相信您可以简单地了解发生了什么。您的regex和replace解决方案应该是这样的

非常感谢。使用xsl:non-matching substring
是个好主意。非常感谢。使用xsl:non-matching substring
是个好主意。很抱歉,我必须用JS回复。不,你真的不必用JS回复。如果你真的很抱歉,那么首先不要回复(或者现在就删除你的答案)。使用正则表达式解析XML是非常困难的。通过发布JS来回答XSLT问题是没有帮助和糟糕的形式。未来读者:不要这样做。对不起,我必须用JS回复。不,你真的不必用JS回复。如果你真的很抱歉,那么首先不要回复(或者现在就删除你的答案)。使用正则表达式解析XML是非常困难的。通过发布JS来回答XSLT问题是没有帮助和糟糕的形式。未来读者:不要这样做。
