使用XProc进行XML流式传输 [英] XML streaming with XProc

问题描述

我正在使用 xproc ，XML管道语言和 http://xmlcalabash.com/.我想找到一个流式处理大型xml文档的示例.例如，给出以下巨大 xml文档:

I'm playing with xproc, the XML pipeline language and http://xmlcalabash.com/. I'd like to find an example for streaming large xml documents. for example, given the following huge xml document:

<Books>
 <Book>
   <title>Book-1</title>
 </Book>
 <Book>
   <title>Book-2</title>
 </Book>
 <Book>
   <title>Book-3</title>
 </Book>

<!-- many many.... -->
 <Book>
   <title>Book-N</title>
 </Book>
</Books>

我应该如何在x-> N个文档(如

How should I proceed to loop (streaming) over x->N documents like

<Books>
 <Book>
   <title>Book-x</title>
 </Book>
</Books>

并使用xslt处理每个文档?xproc有可能吗?

and treat each document with a xslt ? is it possible with xproc ?

推荐答案

在这里，您可以使用XProc来完成此工作，而XProc将与QuiXProc一起流

Here is how you could do it with XProc that would stream with QuiXProc

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="1.0">
  <p:load href="hugedocument.xml"/>
  <p:for-each>
    <p:iteration-source select="/Books/Book"/>
    <p:xslt>
      <p:input port="stylesheet">
        <p:document href="book.xsl"/>
      </p:input>
      <p:input port="parameters">
        <p:empty/>
      </p:input>
    </p:xslt>
  </p:for-each>
  <p:wrap-sequence wrapper="Books"/>    
  <p:store href="hugedocument.res.xml"/>
</p:declare-step>
