태그의 목록을 분리하고 다른

Question

문제는 여러 측면이 있습니다

1. 방법은 태그의 특정 공간이 분리 된 내용을 기준으로 분류 할 수
방법 부족을 분류하는
2. 그러한 특정 내용의
   : I의 모습 출력을 생성 할

   <xsl:param name="pKnownTags"> 
       <t>A</t> 
       <t>B</t> 
   </xsl:param> 
   

   말, 태그 알려 주어지면

   <messages> 
       <m> 
       <subject>message tagged with A B C</subject> 
       <tags>A B C</tags> 
       </m> 
   
       <m> 
       <subject>message tagged with B C D</subject> 
       <tags>B C D</tags> 
       </m> 
   
       <m> 
       <subject>message tagged with X Y A</subject> 
       <tags>X Y A</tags> 
       </m> 
   
       <m> 
       <subject>message tagged with C X</subject> 
       <tags>C X</tags> 
       </m> 
   
       <m> 
       <subject>message tagged with Y</subject> 
       <tags>Y</tags> 
       </m> 
   
   </messages> 
   

   :

는 예를 들어, 다음과 같은 데이터를 가지고

Messages tagged with A: 
* message tagged with A B C 
* message tagged with X Y A 

Messages tagged with B: 
* message tagged with A B C 
* message tagged with B C D 

Messages tagged with neither: 
* message tagged with C X 
* message tagged with Y 

EXSLT를 사용하는 것이 좋지만 그렇지 않으면 1.0 솔루션이 필요합니다. . 이것이 가능한가?

너무 화려하지 않아도됩니다. 시도 아래를주십시오 : 샘플 입력에서 실행

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:exsl="http://exslt.org/common" exclude-result-prefixes="exsl" 
> 
    <xsl:output method="text" indent="yes"/> 

    <xsl:param name="pKnownTags"> 
    <t>A</t> 
    <t>B</t> 
    </xsl:param> 
    <xsl:variable name="pKnownTagsNodeSet" select="exsl:node-set($pKnownTags)/t" /> 

    <xsl:template match="/messages"> 
    <xsl:apply-templates select="$pKnownTagsNodeSet"> 
     <xsl:with-param name="docEl" select="." /> 
    </xsl:apply-templates> 

    <xsl:text>Messages tagged with none of the above:&#xA;</xsl:text> 
    <xsl:apply-templates select="m" mode="checkAbsence" /> 
    </xsl:template> 

    <xsl:template match="t"> 
    <xsl:param name="docEl" select="/.." /> 

    <xsl:value-of select="concat('Messages tagged with ', ., ':&#xA;')"/> 
    <xsl:apply-templates select="$docEl/m[contains(concat(' ', tags, ' '), 
                concat(' ', current(), ' '))]" /> 
    <xsl:text>&#xA;</xsl:text> 
    </xsl:template> 

    <xsl:template match="m" mode="checkAbsence"> 
    <xsl:variable name="currentTagsPadded" select="concat(' ', tags, ' ')" /> 
    <xsl:apply-templates 
      select="(.)[not($pKnownTagsNodeSet[contains($currentTagsPadded, 
                 concat(' ', ., ' '))] 
         ) 
        ]" /> 
    </xsl:template> 

    <xsl:template match="m"> 
    <xsl:value-of select="concat('* ', subject, '&#xA;')"/> 
    </xsl:template> 

</xsl:stylesheet> 

, 이것은 생산 :

Messages tagged with A: 
* message tagged with A B C 
* message tagged with X Y A 

Messages tagged with B: 
* message tagged with A B C 
* message tagged with B C D 

Messages tagged with none of the above: 
* message tagged with C X 
* message tagged with Y

글쎄, 당신의 프로세서가 지원 경우 괜찮습니다 EXSLT str : tokenize() 함수를 사용하면 매우 간단 할 수 있습니다.

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:exsl="http://exslt.org/common" 
xmlns:str="http://exslt.org/strings" 
extension-element-prefixes="exsl str"> 
<xsl:output method="text" encoding="UTF-8"/> 

<xsl:param name="pKnownTags"> 
    <t>A</t> 
    <t>B</t> 
</xsl:param> 

<xsl:variable name="tags-set" select="exsl:node-set($pKnownTags)/t" /> 
<xsl:variable name="xml" select="/" /> 

<xsl:key name="message-by-tags" match="m" use="str:tokenize(tags)" /> 

<xsl:template match="/"> 
    <!-- matching messages --> 
    <xsl:for-each select="$tags-set"> 
     <xsl:variable name="tag" select="." /> 
     <xsl:value-of select="concat('Messages tagged with ', $tag, ':&#10;')"/> 
     <!-- switch context to source document in order to use key --> 
     <xsl:for-each select="$xml"> 
      <xsl:for-each select="key('message-by-tags', $tag)"> 
       <xsl:value-of select="concat('* ', subject, ':&#10;')"/> 
      </xsl:for-each> 
     </xsl:for-each> 
     <xsl:text>&#10;</xsl:text> 
    </xsl:for-each> 

    <!-- non-matching messages --> 
    <xsl:text>Messages tagged with none:&#10;</xsl:text> 
    <xsl:for-each select="messages/m[not(str:tokenize(tags)=$tags-set)]"> 
     <xsl:value-of select="concat('* ', subject)"/> 
     <xsl:if test="position()!=last()"> 
      <xsl:text>&#10;</xsl:text> 
     </xsl:if> 
    </xsl:for-each> 
</xsl:template> 

</xsl:stylesheet>
