초보자가 파이썬에서 XSLT 2.0을 사용하여 xml 파일을 분할하는 방법

Question

xslt 2.0 파일을 통해 여러 xml 파일로 분할하려는 xml 파일이 있습니다. 어떻게해야합니까? 누군가가 단계별 절차를 도와 주실 수 있습니까? 현재 Python 2.7.6을 사용하고 있습니다. 다음 코드를 사용하려고했습니다 :

import lxml.etree as ET 

dom = ET.parse(xml_filename) 
xslt = ET.parse(xsl_filename) 
transform = ET.XSLT(xslt) 
newdom = transform(dom) 
print(ET.tostring(newdom, pretty_print=True)) 

그러나이 값은 없음을 반환합니다.

예 XML 파일

<?xml version="1.0" encoding="UTF-8"?> 
<dataset> 
    <name>dataset containing bounding box labels on images</name> 
    <comment>created by BBTag</comment> 
    <tags> 
     <tag name="Perimeter-SVT" color="#f9e99c"/> 
     <tag name="Perimeter-Vivon" color="#032585"/> 
     <tag name="ScoreBoard-Vivon" color="#bf5786"/> 
     <tag name="Perimeter-StarSports" color="#12dadd"/> 
    </tags> 
    <images>

XSLT 2.0 파일

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="2.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <xsl:template match="//dataset/tags"> 
     <xsl:for-each select="./tag"> 
      <xsl:variable name="tagName" select="@name" /> 

       <xsl:result-document method="xml" href="{$tagName}.xml"> 
        <dataset>  
         <xsl:copy-of select="/dataset/name"/> 
         <xsl:copy-of select="/dataset/comment"/> 
         <tags> 
          <xsl:copy-of select="/dataset/tags/tag[./@name = $tagName]"/> 
         </tags> 
         <images> 
         <xsl:for-each select="/dataset/images/image[./box/label/text() = $tagName]"> 
          <image> 
           <xsl:copy-of select="./@file"/> 
           <xsl:copy-of select="./box[./label[./text() = $tagName]]"/> 
          </image> 
         </xsl:for-each> 
         </images> 
        </dataset> 
       </xsl:result-document>        
     </xsl:for-each> 
    </xsl:template>  
</xsl:stylesheet> 

흐름을 통해 스택을 만족 자세한 내용을 추가. 고맙습니다.

파이썬은 EXSLT exsl:documenthttp://exslt.org/exsl/index.html에게 지원 libxslt를 사용 :

<?xml version="1.0" encoding="utf-8"?> 
<xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:exsl="http://exslt.org/common" 
    extension-element-prefixes="exsl"> 
    <xsl:template match="dataset/tags"> 
    <xsl:for-each select="tag"> 
     <xsl:variable name="tagName" select="@name" /> 

     <exsl:document method="xml" href="{$tagName}.xml"> 
     <dataset> 
      <xsl:copy-of select="/dataset/name"/> 
      <xsl:copy-of select="/dataset/comment"/> 
      <tags> 
      <xsl:copy-of select="/dataset/tags/tag[@name = $tagName]"/> 
      </tags> 
      <images> 
      <xsl:for-each select="/dataset/images/image[box/label = $tagName]"> 
       <image> 
       <xsl:copy-of select="@file"/> 
       <xsl:copy-of select="box[label = $tagName]"/> 
       </image> 
      </xsl:for-each> 
      </images> 
     </dataset> 
     </exsl:document> 
    </xsl:for-each> 
    </xsl:template> 
</xsl:stylesheet>
