我有一些输入长(约3k行)的XML文档,通常看起来像:
<chapter someAttributes="someValues">
<title>someTitle</title>
<p>multiple paragraphs</p>
<p>...</p>
<li>
<p>- some text</p>
</li>
<li>
<p>- some other text</p>
</li>
<!-- another li elements -->
<p>multiple other paragraphs</p>
<p>...</p>
<li>
<p>1. some text</p>
</li>
<li>
<p>2. some other text</p>
</li>
<!-- another li elements -->
<p>multiple other paragraphs</p>
<p>...</p>
<!-- there are other elements such as table, illustration, ul etc. -->
</chapter>
我想要的是用li
ol
元素包裹每个分散(我的意思是段落,表格,插图等){strong>序列 ul
元素}或-
元素取决于某些语义和返回包装的XML。
ul
,那么它应为mark="DASH"
1.
属性2.
,3.
,ol
等开头,那么我希望numeration="ARABIC"
与<ul mark="DASH">
<li>
<p> some text</p>
</li>
<li>
<p> some other text</p>
</li>
<ul>
例如(它只是一个序列):
-
如您所见,我需要剪切“标记所有段落中的字符”,即1.
或2.
,3.
,{ {1}}等等。
输入XML比我描述的更复杂(嵌套序列,表元素中的内部序列),但我正在寻找一些想法,特别是如何 catch&amp;过程具有这种语义的特定序列。
我希望输出XML具有完全相同的顺序,只需要包装li
个元素。如果需要,可以使用XSLT 2.0 / EXSLT。

这是一个XSLT 2.0样式表:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:output indent="yes"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@*, node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="chapter">
<xsl:copy>
<xsl:for-each-group select="*" group-adjacent="boolean(self::li)">
<xsl:choose>
<xsl:when test="current-grouping-key() and ./p[1][starts-with(., '-')]">
<ul mark="DASH">
<xsl:apply-templates select="current-group()"/>
</ul>
</xsl:when>
<xsl:when test="current-grouping-key() and ./p[1][matches(., '[0-9]\.')]">
<ol numeration="arabic">
<xsl:apply-templates select="current-group()"/>
</ol>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
<xsl:template match="li/p/text()[1]">
<xsl:value-of select="replace(., '^(-|[0-9]\.)', '')"/>
</xsl:template>
</xsl:stylesheet>
当我使用Saxon 9.3和样式表以及样本输入
时<chapter someAttributes="someValues">
<title>someTitle</title>
<p>multiple paragraphs</p>
<p>...</p>
<li>
<p>- some text</p>
</li>
<li>
<p>- some other text</p>
</li>
<!-- another li elements -->
<p>multiple other paragraphs</p>
<p>...</p>
<li>
<p>1. some text</p>
</li>
<li>
<p>2. some other text</p>
</li>
<!-- another li elements -->
<p>multiple other paragraphs</p>
<p>...</p>
<!-- there are other elements such as table, illustration, ul etc. -->
</chapter>
我得到以下输出:
<?xml version="1.0" encoding="UTF-8"?>
<chapter>
<title>someTitle</title>
<p>multiple paragraphs</p>
<p>...</p>
<ul mark="DASH">
<li>
<p> some text</p>
</li>
<li>
<p> some other text</p>
</li>
</ul>
<p>multiple other paragraphs</p>
<p>...</p>
<ol numeration="arabic">
<li>
<p> some text</p>
</li>
<li>
<p> some other text</p>
</li>
</ol>
<p>multiple other paragraphs</p>
<p>...</p>
</chapter>

这是一个完整的功能性解决方案,没有任何程序方法,如xsl:for-each-group
和xsl:if
。
XSLT 2.0
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output indent="yes" method="html"/>
<xsl:strip-space elements="*"/>
<!-- identity -->
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<!-- override dash list elements -->
<xsl:template match="li[(name(preceding-sibling::*[position()=1])
!= name(current()))
and matches(.,'^-')]">
<ul mark="DASH">
<li><xsl:apply-templates/></li>
<!-- apply recursive template for adjacent nodes -->
<xsl:apply-templates select="following-sibling::*[1][name()
=name(current())]" mode="next"/>
</ul>
</xsl:template>
<!-- override numeration list elements -->
<xsl:template match="li[(name(preceding-sibling::*[position()=1])
!= name(current()))
and matches(.,'^[0-9]\.')]">
<ol numeration="ARABIC">
<li><xsl:apply-templates/></li>
<xsl:apply-templates select="following-sibling::*[1][name()
=name(current())]" mode="next"/>
</ol>
</xsl:template>
<!-- recursive template for adjacent nodes -->
<xsl:template match="*" mode="next">
<li><xsl:apply-templates/></li>
<xsl:apply-templates select="following-sibling::*[1][name()
=name(current())]" mode="next"/>
</xsl:template>
<!-- remove marks/numeration from first text node -->
<xsl:template match="li/p/text()[1]">
<xsl:value-of select="replace(., '^(-|[0-9]\.)\s+', '')"/>
</xsl:template>
</xsl:stylesheet>
应用于您的输入产生:
<chapter someAttributes="someValues">
<title>someTitle</title>
<p>multiple paragraphs</p>
<p>...</p>
<ul mark="DASH">
<li>
<p>some text</p>
</li>
<li>
<p>some other text</p>
</li>
</ul>
<!-- another li elements -->
<p>multiple other paragraphs</p>
<p>...</p>
<ol numeration="ARABIC">
<li>
<p>some text</p>
</li>
<li>
<p>some other text</p>
</li>
</ol>
<!-- another li elements -->
<p>multiple other paragraphs</p>
<p>...</p>
<!-- there are other elements such as table, illustration, ul etc. -->
</chapter>
