XSLT 导入语句的 Saxon 错误 [英] Saxon error with XSLT import statement

问题描述

每当我有 XSLT 导入语句时，Saxon 处理器都会给我一个错误.这是错误:

The Saxon processor gives me an error whenever I have an XSLT import statement. Here is the error:

XTSE0165: I/O error reported by XML parser processing file: shared/test.xslt (The system cannot find the path specified):

这是我的 XSLT 文档的样子:

Here is how my XSLT document looks like:

<?xml version='1.0' encoding='UTF-8'?>

<xsl:stylesheet version='2.0' 
    xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
    xmlns:fn='http://www.w3.org/2005/02/xpath-functions'
    xmlns:xs='http://www.w3.org/2001/XMLSchema'
    >

    <xsl:import href="shared/test.xslt"/>

...

我的Java代码

TransformerFactory transformerFactory = TransformerFactoryImpl.newInstance();

transformerFactory.setURIResolver(uriResolver);  //my own custom URI resolver

Transformer transformer = transformerFactory.newTransformer(new StreamSource(xsltInputStream));   //this is where the error occurs when I debug!

URI 解析器类永远不会被触发！它阻塞了上面的 newTransformer() 方法......我尝试了 XsltCompiler 等，同样的事情......如果我删除 import 语句，一切正常！它找不到要导入的文件，这很好，但这就是为什么我有解析器类来帮助它定位文件，但它永远不会触发解析器并且无法定位要导入的文件！

The URI resolver class is never triggered! It chocks up on the newTransformer() method above.... I tried XsltCompiler, etc and same thing... If I remove the import statement, everything works!! It can't find the file to import which is fine but that's why I have the resolver class to help it locate the file but it never triggers the resolver and fails locating the file to import!

我该如何解决这个问题?

How do I resolve this?

推荐答案

您可能需要 为您正在加载的 XSLT 的 StreamSource 设置系统 ID.

You likely need to set the System ID for StreamSource of the XSLT that you are loading.

当您从 StreamSource 加载时，它不知道您的 XSLT存在"在哪里，并且难以确定如何解析相对路径.

When you load from a StreamSource, it doesn't know where your XSLT "lives" and has difficulty determining how to resolve relative paths.

StreamSource source = new StreamSource(xsltInputStream);
source.setSystemId(PATH_TO_THE_XSLT_FILE_ON_THE_FILESYSTEM_OR_URL);
Transformer transformer = transformerFactory.newTransformer(source);
