撒克逊人抛出 java.net.SocketException：

Question

乌班图10.4 JRE 1.6.0_26
SaxonHE9.3.0.5

我有一个非常简单的脚本，它从有效的 html 文件中提取文本内容，

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns:html="http://www.w3.org/1999/html"
      version="2.0">
    <xsl:output method="text" encoding="utf-8"/>
</xsl:stylesheet>

在 Oxygen 中运行此脚本会产生预期的输出。

使用相同版本的 java 和 saxon 在命令行上的同一台 PC 上运行此命令，如下所示

java -jar lib/saxonHE-9.3.0.5.jar -o:build/etemp/html_1.txt -s:build/ebook/epub_sh -tei.html -xsl:xslt/htm2text.xsl

输出以下错误

错误 java.net.SocketException：来自服务器的意外文件结尾 转换失败：报告运行时错误

下面是 java 的详细输出

Answer 1

请不要在您能想到的每个论坛上提出相同的问题。选择最合适的，在那里询问，如果没有得到答复，就转向其他地方。在多个地方提问会浪费那些自愿帮助你的人的时间，因为他们看不到这个问题已经在其他地方得到了解答。由于这个原因，否决了这个问题。

Answer 2

对于那些寻找答案的人：

这个问题的答案是解析器试图从这里获取 html dtd http://www.w3.org/1999/html 如样式中所述床单。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns:html="http://www.w3.org/1999/html"
      version="2.0">
    <xsl:output method="text" encoding="utf-8"/>
</xsl:stylesheet>

W3 忽略了请求并且 java 引发了异常。解析器没有表明它正在请求 dtd，也没有表明它尚未收到 dtd。让用户对转换失败的原因一无所知。解析器的行为非常糟糕！

解决方案是告诉解析器使用本地 dtd，通过这样的目录，这是来自 ant 脚本：

<macrodef name="saxon_use_catalog">
    <attribute name="input"/>
    <attribute name="stylesheet"/>
    <attribute name="output"/>
    <sequential>
        <echo>Transforming @{input} to @{output} using @{stylesheet} </echo>
        <java classname="net.sf.saxon.Transform" fork="true" failonerror="true">
            <jvmarg value="-Dxml.catalog.files=lib/xhtml11/dtd/xhtmlcatalog.xml" />
            <classpath>
                <pathelement location="lib/saxonHE-9.3.0.5.jar"/>
                <pathelement location="lib/resolver.jar"/>
                <pathelement location="lib/xhtml11/dtd/xhtmlcatalog.xml"/>
            </classpath>
            <arg value="-r:org.apache.xml.resolver.tools.CatalogResolver"/>
            <arg value="-x:org.apache.xml.resolver.tools.ResolvingXMLReader"/>
            <arg value="-y:org.apache.xml.resolver.tools.ResolvingXMLReader"/>
            <arg value="-s:@{input}"/>
            <arg value="-xsl:@{stylesheet}"/>
            <arg value="-o:@{output}"/>
        </java>
    </sequential>
</macrodef>

我使用的解析器 jar 和目录是用 Oxygen 打包的。
