[英]XSLT xsl:param looping - Return value if found within a text string
Objective : Evaluate each <Report_Entry>
element.目标:评估每个<Report_Entry>
元素。 Return the <Internal_ID>
value if the <External_ID>
value is contained anywhere within the <Addenda>
text.如果<External_ID>
值包含在<Addenda>
文本中的任何位置,则返回<Internal_ID>
值。
My current XSLT returns the desired output but I am looking for a more dynamic/scalable solution.我当前的 XSLT 返回所需的 output 但我正在寻找更动态/可扩展的解决方案。 My XSLT requires that I create 2 xsl:param
statements for each <Integration_Map_Value>
:我的 XSLT 要求我为每个<Integration_Map_Value>
创建 2 个xsl:param
语句:
<xsl:param name="INT-MAP_External_ID_1" select="//Integration_Map_Value[1]/External_ID"/>
<xsl:param name="INT-MAP_Internal_ID_1" select="//Integration_Map_Value[1]/Internal_ID"/>
plus an <xsl:when>
statement:加上一个<xsl:when>
语句:
<xsl:when test="contains(upper-case(Addenda), $INT-MAP_External_ID_1)">
<Internal_ID>
<xsl:value-of select="$INT-MAP_Internal_ID_1"/>
</Internal_ID>
</xsl:when>
Issue: Theoretically there could be an unlimited number of <Integration_Map_Value>
instances so I am looking for a way of dynamically looping through all the <External_ID>
values and comparing them against the <Addenda>
field without having to create an endless amount of parameters, hardcoded instance numbers (ie [1]. [2], [3], etc.), and <xsl:when>
statements.问题:理论上可能存在无限数量的<Integration_Map_Value>
实例,因此我正在寻找一种动态循环所有<External_ID>
值并将它们与<Addenda>
字段进行比较的方法,而无需创建无穷无尽的参数,硬编码的实例编号(即 [1]. [2]、[3] 等)和<xsl:when>
语句。

I've exhausted my beginner XSLT skills and can't seem to figure out a more elegant solution to my problem.我已经用尽了我的初学者 XSLT 技能,似乎无法找到更优雅的解决方案来解决我的问题。 Any help is greatly appreciated.任何帮助是极大的赞赏。 I am open to using XSLT 3.0 but that is very new to me.我愿意使用 XSLT 3.0,但这对我来说很新。
Apologies for the title of this post... struggled to describe my issue.为这篇文章的标题道歉......很难描述我的问题。
Use a simple reference to the particular matching element eg使用对特定匹配元素的简单引用,例如
<xsl:template match="Report_Entry">
<record>
<xsl:apply-templates select="node(), //Integration_Map_Value[contains(upper-case(current()/Addenda), External_ID)]/Internal_ID"/>
</record>
</xsl:template>
plus the identity transformation template plus加上身份转换模板加上
<xsl:template match="root">
<xsl:copy>
<xsl:apply-templates select="Report_Data/Report_Entry"/>
</xsl:copy>
</xsl:template>
The identity transformation can be declared in XSLT 3 through <xsl:mode on-no-match="shallow-copy"/>
, in earlier versions you have to spell it out as身份转换可以通过<xsl:mode on-no-match="shallow-copy"/>
在 XSLT 3 中声明,在早期版本中,您必须将其拼写为
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
