我们如何识别一组节点并将该集合添加到另一个节点中,其中XML源的结构在XSLT中有所不同?

我正在尝试将基于Flash的文本格式转换为基于
HTML的文本.

有< LI>< / LI>源xml中的块我需要添加相邻的< LI>阻止在< ul>内块.

<p></p>
<li></li> ------
<li></li>      | - should be wrapped with <ul> tag
<li></li> ------
<p></p>
<li></li>
<li></li>
<li></li>
<p></p>

最佳答案 以下XSLT 1.0转换为您提供了所需的结果:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:strip-space elements="*"/>
    <xsl:output indent="yes" method="html"/>

    <xsl:key name="list" match="TEXTFORMAT[LI]" use="generate-id(
        (self::*|preceding-sibling::*)[LI][
            not(preceding-sibling::*[1][LI])
        ][last()]
    )" />

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

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

    <!-- Remove <P> tag and set the alignment -->
    <xsl:template match="P">
        <div>
            <xsl:attribute name="style">
                <xsl:apply-templates select="@*" mode="css" />
            </xsl:attribute>
            <xsl:apply-templates/>
        </div>
    </xsl:template>

    <xsl:template match="@ALIGN" mode="css">
        <xsl:value-of select="concat('text-align:', ., ';')"/>
    </xsl:template>
    <!-- add more -->
    <xsl:template match="@*" mode="css" />

    <!-- remove unwanted attributes -->
    <xsl:template match="@LETTERSPACING|@KERNING"/>

    <xsl:template match="TEXTFORMAT[LI]">
        <xsl:variable name="adjacent" select="key('list', generate-id())" />
        <xsl:if test="$adjacent">
            <ul>
                <xsl:apply-templates select="$adjacent/LI" />
            </ul>
        </xsl:if>
    </xsl:template>

    <!-- Replace <LI> with <li> -->
    <xsl:template match="LI">
        <li><xsl:apply-templates/></li>
    </xsl:template>

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

</xsl:stylesheet>

结果:

<div>
   <div style="text-align:LEFT;">
      edfg

   </div>
   <div style="text-align:LEFT;">
      sdgfdsgsds

   </div>
   <ul>
      <li>
         sdfgdsg

      </li>
      <li>
         dsgdfgdsfg

      </li>
      <li><FONT FACE="Lato" SIZE="12" COLOR="#4B4B4B">errytrtyr</FONT></li>
   </ul>
   <div style="text-align:LEFT;">
      sdgfdsgsds

   </div>
   <ul>
      <li><FONT FACE="System" SIZE="16" COLOR="#4B4B4B">nm,hjku
            <FONT FACE="Lato" SIZE="12"></FONT></FONT></li>
      <li><FONT FACE="System" SIZE="16" COLOR="#4B4B4B"><B>hgjgj</B><FONT FACE="Lato" SIZE="12"></FONT></FONT></li>
   </ul>
   <div style="text-align:CENTER;"><FONT FACE="Lato" SIZE="12" COLOR="#4B4B4B">centered text</FONT></div>
</div>

从字面上看,解决方案的关键是这种结构:

<xsl:key name="list" match="TEXTFORMAT[LI]" use="generate-id(
    (self::*|preceding-sibling::*)[LI][
        not(preceding-sibling::*[1][LI])
    ][last()]
)" />

这通过启动当前序列的最近的TEXTFORMAT [LI]的唯一ID索引文档中的每个TEXTFORMAT [LI],即在其之前没有TEXTFORMAT [LI]的最近的TEXTFORMAT [LI].

从那里开始我们可以决定< xsl:template match =“TEXTFORMAT [LI]”>是否为任何给定的TEXTFORMAT [LI]输出内容.
