从 XSLT 2 中元素值的语义层次创建父子元素 [英] Creating parent-child elements from semantic hiearchy in element values in XSLT 2
问题描述
我在 XML 内容中有一系列 P 标记,它们的起始值内具有语义层次结构,但是,P 标记是线性的.寻找 XSLT 2 转换.
I have a series of P tags in XML content that have a semantic hierarchy within their beginning values, however, the P tags are linear. Looking for the XSLT 2 transformation.
语义层次如下:
(1)
+-(a)
+-(I)
+-(A)
使用正则表达式如下:
<xsl:param name="patternOrder" as="element(pattern)*" xmlns="">
<pattern level="1" value="^(\([0-9]+(\.[0-9]+)?\))" />
<pattern level="2" value="^(\([a-z]\))" />
<pattern level="3" value="^(\((IX|IV|V?I{{0,3}})\))" />
<pattern level="4" value="^(\([\w]+(\.[\w]+)?\))" />
</xsl>
在查看我的数据集后,我有各种条件:
After review of my dataset, I have the various conditions:
<?xml version="1.0" encoding="UTF-8"?>
<test>
<content>
<p>(1) blah</p>
<p>(2)(a) blah</p>
<p>(b) blah</p>
<p>(3)(a)(I) blah</p>
<p>(II) blah</p>
<p>(A) blah</p>
<p>(B.1) blah</p>
<p>(b) blah</p>
<p>(4) blah</p>
<p>(4.5) blah</p>
<p>(5)(a)(I)(A) blah</p>
<p>(B) blah</p>
<p>(II) blah</p>
<p>(III)(a) blah</p>
<p>(bb.2) blah</p>
<p>(6) blah</p>
</content>
<content>
<p>blah</p>
</content>
<content>
<p>blah</p>
<p>(1) blah</p>
<p>(a) blah</p>
<p>(b) blah</p>
<p>(2) blah </p>
</content>
</test>
...最终结果应该是:
...and end results should be:
<?xml version="1.0" encoding="UTF-8"?>
<test>
<content>
<p>(1) blah</p>
<p>(2)
<p>(a) blah</p>
<p>(b) blah</p>
</p>
<p>(3)
<p>(a)
<p>(I) blah</p>
<p>(II) blah
<p>(A) blah</p>
<p>(B) blah</p>
</p>
</p>
<p>(b) blah</p>
</p>
<p>(4) blah</p>
<p>(4.5) blah</p>
<p>(5)
<p>(a)
<p>(I)
<p>(A) blah</p>
<p>(B.1) blah</p>
</p>
<p>(II) blah</p>
<p>(III)</p>
<p>(a) blah</p>
<p>(bb.2) blah</p>
</p>
</p>
<p>(6) blah</p>
</content>
<content>
blah
</content>
<content>
blah
<p>(1) blah
<p>(a) blah</p>
<p>(b) blah</p>
</p>
<p>(2) blah </p>
</content>
</test>
请注意如果语义层次结构不存在于 P 标签中的条件 - 则 P 标签被删除并且是其父内容元素的值.
Please note the condition if the semantic hierarchy is not present in the P tag - then the P tag is removed and is a value of its parent content element.
我已经能够使用以下正则表达式检测所有语义条件:
I have been able to detect all the semantic conditions using the following RegEx:
^(\(([\w]+(\.[\w]+)?)\)){1,4}

With the leveling attributes:

<p level="1">(2)</p>
<p level="2">(a) blah</p>

<p level="2">(a)</p>

<p level="3">(III)</p>
<p level="2">(a) blah</p>
<p level="2">(bb.2) blah</p>
<p level="2">(6) blah</p>
</content>
<content>

</content>
<content>
<p>blah</p>
<p level="1">(1) blah</p>
<p level="2">(a) blah</p>
<p level="2">(b) blah</p>
<p level="1">(2) blah </p>
</content>
</test>
推荐答案
第一阶段:改造
<p>(2)(a) blah</p>
<p>(b) blah</p>
进入
<p>(2)</p>
<p>(a) blah</p>
<p>(b) blah</p>
使用类似的东西
<xsl:template match="p">
<xsl:for-each select="tokenize(., '\(')">
<xsl:if test="normalize-space(.)">
<p>(<xsl:value-of select="."/></p>
</xsl:if>
</xsl:for-each>
</xsl:template>
第二阶段:
先写一个函数
<xsl:function name="f:level" as="xs:integer">
<xsl:param name="p" as="element(p)"/>
....
</xsl:function>
根据匹配您的正则表达式计算语义级别".你似乎知道如何做这部分.
which computes the "semantic level" based on matching your regular expressions. You seem to know how to do this part.
然后写一个递归分组函数:
Then write a recursive grouping function:
<xsl:function name="f:group" as="element(p )*">
<xsl:param name="in" as="element(p )*"/>
<xsl:param name="level" as="xs:integer"/>
<xsl:for-each-group select="$in" group-starting-with="p[f:level(.)=$level]">
<p><xsl:value-of select="current-group()[1]"/>
<xsl:sequence select="f:group(current-group()[position() gt 1], $level+1)"/>
</p>
</xsl:for-each-group>
</xsl:function>
并像这样调用这个函数:
and call this function like this:
<xsl:template match="content">
<xsl:sequence select="f:group(p, 1)"/>
</xsl:template>
未测试.
