Question

假设：

<dmodule>
<content>
<procedure>
<mainProcedure>
<proceduralStep>
<proceduralStep id="ps-111-222-test">
<title>Air Valve Assemblies</title>
<proceduralStep>
<title>General</title><proceduralStep><para>Equivalent substitutes can be used for items listed in the Table</para>
</proceduralStep></proceduralStep></proceduralStep>
    <proceduralStep><para>Continue with this</para><para>Hold air valve plate</para></proceduralStep>
    <proceduralStep><para>Turn the screw....</para><para>Install bushing</para></proceduralStep>
    <proceduralStep><para>Hold assembly tool....</para><para>Install spring seat</para></proceduralStep>
    <proceduralStep><para>Install plug</para></proceduralStep>
    </proceduralStep>
    <proceduralStep>
<proceduralStep id="ps-111-223-test">
<title>Water Valve Assemblies</title>
<proceduralStep>
<title>General</title><proceduralStep><para>Equivalent substitutes can be used for items listed in the Table</para>
</proceduralStep></proceduralStep></proceduralStep>
    <proceduralStep><para>Continue with this</para><para>Rotate water valve plate</para></proceduralStep>
    <proceduralStep><para>Install housing....</para><para>Install bushing</para></proceduralStep>
    <proceduralStep><para>Hold water valve plate....</para><para>Install spring seat</para></proceduralStep>
    <proceduralStep><para>Install actuator assembly</para></proceduralStep>
    </proceduralStep>
    </mainProcedure>
    </procedure>
</content>
</dmodule>

我正在使用<xsl:number>来计算<proceduralStep>，不包括任何具有属性@changeType='delete'的父级或子级的proceduralStep。（proceduralSteps可以嵌套。）

    <xsl:template match="proceduralStep">
        <fo:list-block>
            <fo:list-item>
                <fo:list-item-label>
                    <fo:block>
                        <xsl:number count="proceduralStep[not(*/@changeType = 'delete' or parent::*/@changeType = 'delete')]" from="content" level="multiple" format="1.1.1.1.1"/>
                    </fo:block>
                </fo:list-item-label>
            </fo:list-item>
        </fo:list-block>
</xsl:template>

这是按预期工作的，除非<revst>是<proceduralStep>

的包装器

<dmodule>
    <content>
    <procedure>
    <mainProcedure>
    <proceduralStep>
    <proceduralStep id="ps-111-222-test">
    <title>Air Valve Assemblies</title>
    <proceduralStep>
    <title>General</title><proceduralStep><para>Equivalent substitutes can be used for items listed in the Table</para>
    </proceduralStep></proceduralStep></proceduralStep>
        <proceduralStep><para>Continue with this</para><para>Hold air valve plate</para></proceduralStep>
        <proceduralStep><para>Turn the screw....</para><para>Install bushing</para></proceduralStep>
        <proceduralStep><para>Hold assembly tool....</para><para>Install spring seat</para></proceduralStep>
        <proceduralStep><para>Install plug</para></proceduralStep>
        </proceduralStep>
        <proceduralStep>
    <proceduralStep id="ps-111-223-test">
    <title>Water Valve Assemblies</title>
    <proceduralStep>
    <title>General</title><proceduralStep><para>Equivalent substitutes can be used for items listed in the Table</para>
    </proceduralStep></proceduralStep></proceduralStep>
        <proceduralStep><para>Continue with this</para><para>Rotate water valve plate</para></proceduralStep>
        <revst changeMark="1">
        <proceduralStep><para>Install housing....</para><para>Install bushing</para></proceduralStep>
        <proceduralStep><para>Hold water valve plate....</para><para>Install spring seat</para></proceduralStep>
        </revst>
        <proceduralStep><para>Install actuator assembly</para></proceduralStep>
        </proceduralStep>
        </mainProcedure>
        </procedure>
    </content>
    </dmodule>

然后重新开始编号：

    1.2.13 Continue with this. Rotate water valve plate
    1.2.1  Install housing...Install bushing
    1.2.2  Hold water valve plate....Install spring seat
    1.2.14 Install actuator assembly

而不是：

    1.2.13 Continue with this. Rotate water valve plate
    1.2.14 Install housing...Install bushing
    1.2.15 Hold water valve plate....Install spring seat
    1.2.16 Install actuator assembly

所以我试过

<xsl:number count="revst[not(@changeType = 'delete')] |  proceduralStep[not(*/@changeType = 'delete' or parent::*/@changeType = 'delete')]" from="content" level="multiple" format="1.1.1.1.1"/>

现在我来了

    1.2.13 Continue with this. Rotate water valve plate
    1.2.14.1 Install housing...Install bushing
    1.2.14.2 Hold water valve plate....Install spring seat
    1.2.15 Install actuator assembly

我认为xsl:number应该忽略计数表达式中没有的任何元素。

Answer 1

xsl:number计算兄弟姐妹（或level="any"，计算preceding和ancestor-or-self轴。见https://www.w3.org/TR/xslt#number。因此，当它计算revst中的兄弟姐妹时，它正在做它应该做的事情。

我首选的解决方案是在早期处理阶段将<revst>和</revst>转变为单独的里程碑＆＃39;在处理列表编号之前，空元素（以fo:change-bar-begin和fo:change-bar-end的方式）。

如果没有，你必须自己进行多级计数（如果你使用的是XSLT 2.0而不是XSLT 1.0，那就不那么冗长了）：

<xsl:template name="preceding-step-count">
  <xsl:value-of
    select="count(preceding-sibling::proceduralStep[not(*/@changeType = 'delete' or parent::*/@changeType = 'delete')]) +
    count(preceding-sibling::revst/proceduralStep[not(*/@changeType = 'delete' or parent::*/@changeType = 'delete')])"/>
</xsl:template>

<xsl:template match="proceduralStep">
  <xsl:param name="current-count" select="0"/>
  <xsl:param name="parent-label" />

  <xsl:variable name="preceding-step-count">
    <xsl:call-template name="preceding-step-count" />
  </xsl:variable>

  <xsl:variable name="label">
    <xsl:value-of
      select="$current-count + $preceding-step-count + 1"/>
  </xsl:variable>

  <xsl:variable name="use-label">
    <xsl:choose>
      <xsl:when test="$parent-label">
        <xsl:value-of select="concat($parent-label, '.', $label)"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$label"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  <fo:list-block provisional-distance-between-starts="36pt">
    <fo:list-item>
      <fo:list-item-label end-indent="label-end()">
        <fo:block>
          <xsl:value-of select="$use-label"/>
        </fo:block>
      </fo:list-item-label>
      <fo:list-item-body start-indent="body-start()">
        <xsl:apply-templates>
          <xsl:with-param name="parent-label" select="$use-label" />
        </xsl:apply-templates>
      </fo:list-item-body>
    </fo:list-item>
  </fo:list-block>
</xsl:template>

<xsl:template match="revst">
  <xsl:param name="parent-label" />

  <!-- If using XSLT 2.0, could use tunnel parameters
    and avoid passing $parent-label. -->
  <xsl:apply-templates>
    <xsl:with-param name="current-count">
      <xsl:call-template name="preceding-step-count" />
    </xsl:with-param>
    <xsl:with-param name="parent-label" select="$parent-label" />
  </xsl:apply-templates>
</xsl:template>

<xsl:template match="para | title">
  <fo:block>
    <xsl:apply-templates />
  </fo:block>
</xsl:template>

当count元素被包装xslt 1.0 xsl-fo时，xsl：number重新启动
