XSL-FO中的步骤编号

时间:2015-09-28 13:06:04

标签: xml xslt xsl-fo

一直苦苦挣扎,现在要求帮助。我正在尝试获取正确的数字,以便在使用XSL-FO时在PDF输出上引用它时显示一个步骤。在之前得到的帮助下,我有其他参考工作。这些特殊标签给我带来了麻烦。

这是针对S1000D航空航天出版物规范中的故障隔离树:

<isolationStep id="step4"><isolationStepQuestion>Check for burnt-out lamps. Are lamps good?</isolationStepQuestion><isolationStepAnswer><yesNoAnswer><yesAnswer nextActionRefId="step6"/><noAnswer nextActionRefId="step8"/></yesNoAnswer></isolationStepAnswer></isolationStep>

正如您所看到的,该问题有一个答案部分。这些答案已经适用于其他步骤。在PDF中我得到了正确编号的步骤,但在渲染答案时我得到了这个:

XSL-FO用于问题,答案以及尝试编号来回答引用的步骤:

此外,链接正常工作,并将您带到正确的位置。我正好让它正确编号。

这是一个XSL 2.0样式表。感谢任何帮助,提前谢谢。

答案 0 :(得分:2)

//isolationStep正在选择文档中的每个isolationStep,因此您需要获取每个//isolationStep[@id=$ref] | //isolationProcedureEnd[@id=$ref]的数量。

您可能一直试图获得&#34; isolationStep的效果,但您可能更善于使用密钥查找isolationProcedureEndisolationStep按他们的ID。

密钥在http://www.w3.org/TR/xslt20/#key

定义

您可以定义一个键,用@id元素查找<xsl:key name="isolationSteps" match="isolationStep" use="@id" /> 元素作为样式表中的顶级元素:

key()

在您的模板中,使用isolationStep功能查找匹配@id值的<xsl:template match="yesAnswer"> <xsl:variable name="ref" select="@nextActionRefId"/> <fo:block space-before="4pt" space-after="4pt" keep-with-previous="always"> <fo:inline><xsl:text>Yes: Go to </xsl:text> <fo:basic-link internal-destination="{@nextActionRefId}" color="blue">Step <!--<xsl:value-of select="$yesref2"/>--> <!--ancestor::isolationMainProcedure--> <!--<xsl:apply-templates select="an../../../.././isolationStep | isolationProcedureEnd[@id=$yesref]" mode="nbr"/> ancestor::isolationMainProcedure[1]/--> <xsl:apply-templates select="key('isolationSteps', $ref)" mode="nbr"/> </fo:basic-link></fo:inline> </fo:block> </xsl:template>
