的xsl：数重新启动时计数元件被包裹XSLT 1.0 XSL-FO

Question

鉴于：

<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> 

我使用<xsl:number>计数<proceduralStep>，不含具有父或子带属性@changeType='delete'任何proceduralStep。 （proceduralSteps可以被嵌套。）

<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> 

可正常工作，除非<revst>是<proceduralStep>

<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> 

的包装之后的编号被重新启动：

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 

代替：

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，我想

<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"/> 

而现在我越来越

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 

我想xsl:number应该不会忽略任何元素计数表达。

Answer 1

xsl:number计数的兄弟姐妹（或者，对于level="any"，沿着preceding和ancestor-or-self轴计数）。见https://www.w3.org/TR/xslt#number。所以当它计算revst中的兄弟姐妹时，它正在执行它的意图。

我的优选的解决办法是为早期处理阶段处理之前已打开与<revst>和</revst>成单独的“里程碑的”空元素（在fo:change-bar-begin和fo:change-bar-end的方式）做列表编号。

在没有这一点，你必须做你自己的多层次计数（如果你使用的XSLT 1.0代替XSLT 2.0这将是更简洁）：

<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>
