如何根据 'sec/@disp-level' 值在 'sec/title' 元素下生成格式化数字序列

Question

这里我们根据'sec/@disp-level'生成title元素下的数字序列，下面是定义的层级格式（谁能帮帮我):

@disp-level='1' = I., II., III.等等
@disp-level='2' = A., B., C. 等等
@disp-level='3' = 1., 2., 3. 等等
@disp-level='4' = a., b., c.等等
@disp-level='5' = (1), (2), (3) 等等

示例：在这个例子中是罗马数字。需要继续。

I.何时可以启动程序

III. 管辖权和地点

注意 - 我们在每个部分下进行排序。

Answer 1

我用 xmlstarlet 做了这个：

$ xmlstarlet sel -t -m //title -v "named-content"  -o "," -v . -n input.xml
§15.1,§15.1  I.  WHEN PROCEEDINGS MAY BE INITIATED
,III. JURISDICTION AND VENUE
,A.   Trusts Under Continuing Court Jurisdiction
,A.   Pursuit of Claims
§15.2,§15.2  1.  Supervised Versus Unsupervised Trusts
§15.3,§15.3  3.  Removal From Continuing Court Jurisdiction
§15.3A,§15.3A a.  Mandatory Removal for Trust With Corporate Trustee
§15.3B,§15.3B 2.  Discretionary Removal for Trust With Individual Trustee
§15.35,§15.35 (1) Consent or Affirmation by Beneficiaries
§15.35A,§15.35A    (1) Consent or Affirmation by Beneficiaries (Added Section 5)
,VI.  LITIGATION INVOLVING TRUSTEE AND THIRD PARTIES

和 output.xml 相同：

$ xmlstarlet sel -t -m //title -v "named-content"  -o "," -v . -n output.xml
§15.1,§15.1  I.  WHEN PROCEEDINGS MAY BE INITIATED
,II.  JURISDICTION AND VENUE
,A.   Trusts Under Continuing Court Jurisdiction
,B.   Pursuit of Claims
§15.2,§15.2  1.  Supervised Versus Unsupervised Trusts
§15.3,§15.3  2.  Removal From Continuing Court Jurisdiction
§15.3A,§15.3A a.  Mandatory Removal for Trust With Corporate Trustee
§15.3B,§15.3B b.  Discretionary Removal for Trust With Individual Trustee
§15.35,§15.35 (1) Consent or Affirmation by Beneficiaries
§15.35A,§15.35A    (2) Consent or Affirmation by Beneficiaries (Added Section 5)
,III. LITIGATION INVOLVING TRUSTEE AND THIRD PARTIES

是的，我看到您的输入和输出之间存在一些差异，但不清楚 'desired change' 是什么。

Answer 2

我认为您只是想将 xsl:number 与适当的 format 一起使用：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="#all"
    version="3.0">
 
  <xsl:param name="formats" as="map(xs:string, xs:string)"
    select="map { '1' : 'I.', '2' : 'A.', '3' : '1.', '4' : 'a.', '5' : '(1)' }"/>

  <xsl:mode on-no-match="shallow-copy"/>

  <xsl:template match="sec[@disp-level]/title/text()[1]">
      <xsl:variable name="number" as="xs:string">
          <xsl:number count="sec[@disp-level]" format="{$formats(current()/../../@disp-level)}"/>
      </xsl:variable>
      <xsl:value-of select="replace(., '^\s*\(?[A-Z0-9.]+\)?', $number)"/>
  </xsl:template>
  
</xsl:stylesheet>

https://xsltfiddle.liberty-development.net/naZYrqt

这是 XSLT 3 使用 XPath 3.1 映射来存储从级别编号到级别格式的映射，但当然它可以在 XML 变量或早期版本的 XSLT 中的序列中建模：

 <xsl:param name="formats" as="xs:string*"
    select="'I.', 'A.', '1.', 'a.', '(1)'"/>

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
    
  <xsl:template match="sec[@disp-level]/title/text()[1]">
      <xsl:variable name="number" as="xs:string">
          <xsl:number count="sec[@disp-level]" format="{$formats[position() = current()/../../@disp-level]}"/>
      </xsl:variable>
      <xsl:value-of select="replace(., '^\s*\(?[A-Z0-9.]+\)?', $number)"/>
  </xsl:template>
