在 xslt 输出中获取冗余以及如何在 xslt 输出中获取精确的元素序列作为输入

Question

我是 XSLT 的新手。我正在将 XML 文档转换为 XHTML 格式。在我的 XSLT 输出中，我得到了冗余并且没有得到输出中元素的确切序列作为输入。

我应用的 XSLT：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/1999/xhtml">
  <xsl:output method="html" omit-xml-declaration="yes"
  indent="yes" />
  <xsl:strip-space elements="*" />
  <xsl:template match="/">
    <xsl:apply-templates select="//TLV1"/>
  </xsl:template>
  <xsl:template match="TLV1">
    <div>
      <xsl:attribute name="class">TLV1</xsl:attribute>
      <xsl:if test="P">
        <xsl:for-each select="P">
          <div>
            <xsl:attribute name="class">P</xsl:attribute>
            <xsl:apply-templates select="node()[1]" />
            <xsl:if test="E">
              <xsl:for-each select="E">
                <span>
                  <xsl:attribute name="class">emph_I</xsl:attribute>
                  <xsl:apply-templates />
                </span>
                <xsl:apply-templates select="following-sibling::node()[1]" />
              </xsl:for-each>
            </xsl:if>
          </div>
        </xsl:for-each>
        <xsl:if test="LK">
          <xsl:for-each select="LK">
            <xsl:value-of select="LK"/>
          </xsl:for-each>
        </xsl:if>
      </xsl:if>
    </div>
  </xsl:template>
</xsl:stylesheet>

当我将此 xslt 应用于输入时，所有“P”元素首先处理，然后是“LK”，所以我失去了输出顺序。并在“div”和“span”元素中获得冗余。

我的输出：

<div xmlns="http://www.w3.org/1999/xhtml" class="TLV1">
  <div class="P">All rights reserved.</div>
  <div class="P">
    Production Services:<span class="emph_I">Production Services:</span>Aptara, Inc.
  </div>
  <div class="P">

    Roitman, EdD, FACSM
  </div>
  <div class="P">
    ACSM Group Publisher:<span class="emph_I">ACSM Group Publisher:</span>D. Mark Robertson
  </div>
  <div class="P">&nbsp;&nbsp;&nbsp;p. cm.</div>
  <div class="P">

    service department at
    <span class="emph_I">(301) 223-2320</span>. International customers should call.

  <div class="P">

    am to 6:00 pm, EST.
  </div>
  <div class="LK">
    ABCD !!!!!!
  </div>
  <div class="LK">
    WXYZ !!!!!!
  </div>
</div>

在“LK”处理之后首先处理的所有“P”元素。而 ACSM Group Publisher：在“div”和“span”中获得了 2 次。

预期输出：我想要这个输出..

  <div class="P">All rights reserved.</div>
  <div class="P">
    <span class="emph_I">Production Services:</span>Aptara,Inc.

抱歉发了这么久！！

您需要让模板在这里为您完成工作，而不是一堆ifs 和for-eaches：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns="http://www.w3.org/1999/xhtml">
  <xsl:output method="html" omit-xml-declaration="yes" indent="yes" />
  <xsl:strip-space elements="*" />

  <xsl:template match="/">
    <xsl:apply-templates select="//TLV1"/>
  </xsl:template>

  <xsl:template match="TLV1 | P | LK">
    <div class="{local-name()}">
      <xsl:apply-templates />
    </div>
  </xsl:template>

  <xsl:template match="E">
    <span class="emph_I">
      <xsl:apply-templates />
    </span>
  </xsl:template>
</xsl:stylesheet>

在您的示例输入上运行时，结果是：

<div class="TLV1" xmlns="http://www.w3.org/1999/xhtml">
  <div class="P">All rights reserved.</div>
  <div class="P">
    <span class="emph_I">Production Services:</span>Aptara, Inc.
  </div>
  <div class="LK">ABCD !!!!!!</div>
  <div class="P">
    <span class="emph_I">ACSM's Publications Committee Chair:</span>Jeffrey L.
    Roitman, EdD, FACSM
  </div>
  <div class="P">
    <span class="emph_I">ACSM Group Publisher:</span>D. Mark Robertson
  </div>
  <div class="LK">WXYZ !!!!!!</div>
  <div class="P">   p. cm.</div>
  <div class="P">
    To purchase additional copies of this book, call our customer
    service department at
    <span class="emph_I">(301) 223-2320</span>. International customers should call.
  </div>
  <div class="P">

  </div>
</div>

您的控制流在这里似乎不必要地复杂化。在大多数情况下，更好的方法是从身份转换开始，为您要处理的每个案例添加模板，然后递归调用<xsl:apply-templates> 来选择当前节点的每个子节点并依次设置其样式（及其内容） .尽可能编写规则——一般和例外——而不是程序。

此外，当您不需要计算属性的值时，您确实应该更多地利用文字结果属性。

如果我没看错你的代码，你想要的是：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

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

  <xsl:template match="TLV1">
    <div class="TLV1">
      <xsl:apply-templates/>
    </div>
  </xsl:template>

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

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

  <xsl:template match="E">
    <span class="emph_I"> 
      <xsl:apply-templates/>
    </span>
  </xsl:template>


</xsl:stylesheet>
