xslt-1.0使用<h1>和</h1> <h2>创建xml标签

时间：2018-11-05 04:19:25

标签： xml xslt xslt-1.0 xslt-grouping

我对xslt非常陌生。我想将下面的输入转换为输出。我想将h1和h2元素分组，创建属性并在2个h1或h2标签之间添加数据作为子标签值。请帮忙。谢谢。

input.xml 

<ATTRIBUTE-VALUE>
    <THE-VALUE>
        <div xmlns="http://www.w3.org/1999/xhtml">
            <h1 dir="ltr" id="_1536217498885">Main Description</h1>
            <p>Line1 The main description text goes here.</p>
            <p>Line2 The main description text goes here.</p>
            <h1 dir="ltr" id="_1536217498886">Steps</h1>
            <h2 dir="ltr" id="_1536217498886">Section Name One</h2>
            <p>Line1 The steps text goes here.</p>
            <ul>Line2 The section description text goes here.</ul>
            <h2 dir="ltr" id="_1536217498886">Section Name Two</h2>
            <p>Line1 The key consideration text goes here.</p>
            <ul><li>Line2 The key consideration text goes here.</li></ul>
            <h1 dir="ltr" id="_1536217498887">Skills</h1>
            <p>Line1 The Skills text goes here.</p>
            <p>Line2 The Skills text goes here.</p>
            <p>Line3 The Skills text goes here.</p>
            <h1 dir="ltr" id="_1536217498888">Synonyms</h1>
            <p>The Synonyms text goes here.</p>
        </div>
    </THE-VALUE>
</ATTRIBUTE-VALUE>

output.xml 

<MainDescription>
    <![CDATA[
        <p>Line1 The main description text goes here.</p>
        <p>Line2 The main description text goes here.</p>
    ]]>
</MainDescription>
<Section name="Section Name One">
    <Description>
        <p>Line1 The section text goes here.</p>
        <p>Line2 The description text goes here.</p>
    </Description>
</Section>
<Section name="Section Name Two">
    <Description>
        <p>Line1 The description text goes here.</p>
        <ul><li>Line2 The description text goes here.</li></ul>
    </Description>
</Section>
<Skills>
    <p>Line1 The Skills text goes here.</p>
    <p>Line2 The Skills text goes here.</p>
    <p>Line3 The Skills text goes here.</p>
</Skills>
<Synonyms>
    <p>The Synonyms text goes here.</p>
</Synonyms>

我在xsl之下使用过标签分组，但是我无法获得output.xml所需的标签。如果我对h1和h2都应用相同的模板，则只能得到xsl以下的h1或h2的结果。

xsl文件：

<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xhtml="http://www.w3.org/1999/xhtml"
    xmlns:exsl="http://exslt.org/common"
    exclude-result-prefixes="xhtml exsl"
    version="1.0">

  <xsl:import href="http://lenzconsulting.com/xml-to-string/xml-to-string.xsl"/>

  <xsl:output method="xml" indent="yes"
    cdata-section-elements="MainDescription KeyConsideration"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/">
      <xsl:apply-templates/>
  </xsl:template>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:key name="h1-group" match="xhtml:div/*[not(self::xhtml:h1)]" use="generate-id(preceding-sibling::xhtml:h1[1])"/>

  <xsl:template match="xhtml:div[xhtml:h1]">
      <xsl:apply-templates select="xhtml:h1"/>
  </xsl:template>

  <xsl:template match="xhtml:h1">
      <xsl:element name="{translate(., ' ', '')}">
          <xsl:variable name="rtf-with-xhtml-ns-stripped">
              <xsl:apply-templates select="key('h1-group', generate-id())"/>
          </xsl:variable>
          <xsl:apply-templates select="exsl:node-set($rtf-with-xhtml-ns-stripped)/node()" mode="xml-to-string"/>
      </xsl:element>
  </xsl:template>

  <xsl:template match="xhtml:p">
      <p>
          <xsl:apply-templates/>
      </p>
  </xsl:template>

</xsl:stylesheet>

我认为您需要为h2分组定义第二个键

<xsl:key name="h2-group" match="xhtml:div/*[not(self::xhtml:h2)]" use="generate-id(preceding-sibling::xhtml:h2[1])"/>

然后有第二个模板，该模板与组中包含h1个元素的h2个元素匹配

<xsl:template match="xhtml:h1[key('h1-group', generate-id())[self::xhtml:h2]]">
  <xsl:apply-templates select="key('h1-group', generate-id())[self::xhtml:h2]" />
</xsl:template>

然后在匹配h2的模板中进行分组

<xsl:template match="xhtml:h2">
  <xsl:variable name="h1Group" select="key('h1-group', generate-id(preceding-sibling::xhtml:h1[1]))" />
  <Section name="{.}">
    <Description>
      <xsl:apply-templates select="key('h2-group', generate-id())[count(. | $h1Group) = count($h1Group)]"/>
   </Description>
  </Section>
</xsl:template>

此处使用count是为了确保您只选择h2组中当前h1之后的元素。

尝试使用此XSLT 

<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xhtml="http://www.w3.org/1999/xhtml"
    xmlns:exsl="http://exslt.org/common"
    exclude-result-prefixes="xhtml exsl"
    version="1.0">

  <xsl:import href="http://lenzconsulting.com/xml-to-string/xml-to-string.xsl"/>

  <xsl:output method="xml" indent="yes" cdata-section-elements="MainDescription KeyConsideration"/>
  <xsl:strip-space elements="*"/>

  <xsl:key name="h1-group" match="xhtml:div/*[not(self::xhtml:h1)]" use="generate-id(preceding-sibling::xhtml:h1[1])"/>
  <xsl:key name="h2-group" match="xhtml:div/*[not(self::xhtml:h2)]" use="generate-id(preceding-sibling::xhtml:h2[1])"/>

  <xsl:template match="/">
      <xsl:apply-templates/>
  </xsl:template>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="xhtml:div[xhtml:h1]">
      <xsl:apply-templates select="xhtml:h1"/>
  </xsl:template>

  <xsl:template match="xhtml:h1">
      <xsl:element name="{translate(., ' ', '')}">
          <xsl:choose>
            <xsl:when test=". = 'Main Description'">
              <xsl:variable name="rtf-with-xhtml-ns-stripped">
                <xsl:apply-templates select="key('h1-group', generate-id())"/>
              </xsl:variable>
              <xsl:apply-templates select="exsl:node-set($rtf-with-xhtml-ns-stripped)/node()" mode="xml-to-string"/>
            </xsl:when>
            <xsl:otherwise>
              <xsl:apply-templates select="key('h1-group', generate-id())"/>
            </xsl:otherwise>
          </xsl:choose>
      </xsl:element>
  </xsl:template>

  <xsl:template match="xhtml:h1[key('h1-group', generate-id())[self::xhtml:h2]]">
    <xsl:apply-templates select="key('h1-group', generate-id())[self::xhtml:h2]" />
  </xsl:template>  

  <xsl:template match="xhtml:h2">
    <xsl:variable name="h1Group" select="key('h1-group', generate-id(preceding-sibling::xhtml:h1[1]))" />
    <Section name="{.}">
      <Description>
        <xsl:apply-templates select="key('h2-group', generate-id())[count(. | $h1Group) = count($h1Group)]"/>
      </Description>
    </Section>
  </xsl:template>

  <xsl:template match="xhtml:p|xhtml:ul|xhtml:li">
      <xsl:element name="{local-name()}">
          <xsl:apply-templates/>
      </xsl:element>
  </xsl:template>
</xsl:stylesheet>
