java - 如何验证内部网页上的 CSS？

Question

我想查看内部网页，所以我不能使用 W3C validation直接服务。我设法在本地运行 XHTML validator ，但是，我在使用 css-validator 时遇到了一些问题。我真的不想设置 Tomcat或 Jigsaw为了能够运行 Java servlet，命令行选项给了我一条错误消息

Exception in thread "main" java.lang.NoClassDefFoundError: 
org.w3c.tools.resources.ProtocolException at 
org.w3c.css.css.CssValidator.main(CssValidator.java:164)

如何在 Linux 机器上验证本地 CSS？

Answer 1

That jar是可运行的，但它需要一些额外的库。

检查 MANIFEST.MF文件:

$ unzip -p css-validator.jar META-INF/MANIFEST.MF
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.0
Created-By: 1.6.0_26-b03 (Sun Microsystems Inc.)
Main-Class: org.w3c.css.css.CssValidator
Class-Path: . lib/commons-collections-3.2.1.jar lib/commons-lang-2.6.j
 ar lib/jigsaw.jar lib/tagsoup-1.2.jar lib/velocity-1.7.jar lib/xerces
 Impl.jar lib/xml-apis.jar lib/htmlparser-1.3.1.jar

您需要 Class-Path 中提到的所有 jar。您可以从 maven repository 下载它们使用这个脚本:

#!/bin/bash

set -e

mkdir -p lib
curl -LO http://www.w3.org/QA/Tools/css-validator/css-validator.jar
echo "\
http://repo1.maven.org/maven2/commons-collections/commons-collections/3.2.1/commons-collections-3.2.1.jar
http://repo1.maven.org/maven2/commons-lang/commons-lang/2.6/commons-lang-2.6.jar
http://repo1.maven.org/maven2/org/w3c/jigsaw/jigsaw/2.2.6/jigsaw-2.2.6.jar jigsaw.jar
http://repo1.maven.org/maven2/org/ccil/cowan/tagsoup/tagsoup/1.2/tagsoup-1.2.jar
http://repo1.maven.org/maven2/org/apache/velocity/velocity/1.7/velocity-1.7.jar
http://repo1.maven.org/maven2/xerces/xercesImpl/2.11.0/xercesImpl-2.11.0.jar xercesImpl.jar
http://repo1.maven.org/maven2/nu/validator/htmlparser/htmlparser/1.2.1/htmlparser-1.2.1.jar\
" | while read url shortname; do
        if [ -z "$shortname" ]; then
            shortname="${url##*/}"
        fi
        curl -L -o "lib/${shortname}" "${url}"
    done

这样做之后，它起作用了:

$ java -jar css-validator.jar --output=soap12 file:badcss.html
{vextwarning=false, output=soap12, lang=en, warning=2, medium=all, profile=css3}
