How can I validate CSS on internal web pages?
That jar is runnable, but it needs some extra libraries.
Examine the MANIFEST.MF file:
$ unzip -p css-validator.jar META-INF/MANIFEST.MFManifest-Version: 1.0Ant-Version: Apache Ant 1.8.0Created-By: 1.6.0_26-b03 (Sun Microsystems Inc.)Main-Class: org.w3c.css.css.CssValidatorClass-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.jarYou need all the jars mentioned in Class-Path. You can download them from the maven repository using this script:
#!/bin/bashset -emkdir -p libcurl -LO http://www.w3.org/QA/Tools/css-validator/css-validator.jarecho "\http://repo1.maven.org/maven2/commons-collections/commons-collections/3.2.1/commons-collections-3.2.1.jarhttp://repo1.maven.org/maven2/commons-lang/commons-lang/2.6/commons-lang-2.6.jarhttp://repo1.maven.org/maven2/org/w3c/jigsaw/jigsaw/2.2.6/jigsaw-2.2.6.jar jigsaw.jarhttp://repo1.maven.org/maven2/org/ccil/cowan/tagsoup/tagsoup/1.2/tagsoup-1.2.jarhttp://repo1.maven.org/maven2/org/apache/velocity/velocity/1.7/velocity-1.7.jarhttp://repo1.maven.org/maven2/xerces/xercesImpl/2.11.0/xercesImpl-2.11.0.jar xercesImpl.jarhttp://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}" doneAfter doing that, it works:
$ java -jar css-validator.jar --output=soap12 file:badcss.html{vextwarning=false, output=soap12, lang=en, warning=2, medium=all, profile=css3}<?xml version='1.0' encoding="utf-8"?><env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"> <env:Body> <m:cssvalidationresponse env:encodingStyle="http://www.w3.org/2003/05/soap-encoding" xmlns:m="http://www.w3.org/2005/07/css-validator"> <m:uri>file:badcss.html</m:uri> <m:checkedby>http://jigsaw.w3.org/css-validator/</m:checkedby> <m:csslevel>css3</m:csslevel> <m:date>2013-03-12T06:40:09Z</m:date> <m:validity>false</m:validity> <m:result> <m:errors xml:lang="en"> <m:errorcount>1</m:errorcount> <m:errorlist> <m:uri>file:badcss.html</m:uri> <m:error> <m:line>8</m:line> <m:errortype>parse-error</m:errortype> <m:context> h1 </m:context> <m:errorsubtype> exp </m:errorsubtype> <m:skippedstring> 100% </m:skippedstring> <m:message> Property fnt-size doesn't exist : </m:message> </m:error> </m:errorlist> </m:errors> <m:warnings xml:lang="en"> <m:warningcount>1</m:warningcount> <m:warninglist> <m:uri>file:badcss.html</m:uri> <m:warning> <m:line>5</m:line> <m:level>0</m:level> <m:message>You should add a 'type' attribute with a value of 'text/css' to the 'style' element</m:message> </m:warning> </m:warninglist> </m:warnings> </m:result> </m:cssvalidationresponse> </env:Body></env:Envelope>
You can invoke the W3C validator from the command line:
Command-Line use
Any computer with Java installed can also run the validator from the terminal/console as a commandline tool. Download the css-validator.jar jar archive (or build it with ant jar) and run it as :
java -jar css-validator.jar http://www.w3.org/Note : the
css-validator.jarfile must be located at the exact same level as the lib/ folder to work properly.
Update: To get it to work, I checked out the full distribution from CVS and ran ant using the included build.xml. It downloaded all dependencies except for servlet.jar. To deal with that, I downloaded the binary distribution of Tomcat 6 and extracted it. Then, I edited the build.xml for css-validator to reflect the location of servlet.lib:
<property name="servlet.lib" value="E:/Downloads/apache-tomcat-6.0.20/lib/servlet-api.jar"/>Then ran ant again. This produced the css-validator.jar file in the top level of the directory checked out from CVS with the lib subdirectory containing the other jars it depends on. Then, I was able to run the validator successfully:
C:\Temp\validator\2002\css-validator> java -jar css-validator.jar http://www.unur.com/
For the lazy, here's a script I wrote to do what Sinan suggests:
#!/bin/sh# W3C CSS Validator Install Script --------------# installs W3C CSS Validator# requires: ant, wget, javac# see: http://jigsaw.w3.org/css-validator/DOWNLOAD.html# see: http://esw.w3.org/CssValidator# see: http://thecodetrain.co.uk/2009/02/running-the-w3c-css-validator-locally-from-the-command-line/# see: http://stackoverflow.com/a/3303298/357774##wget "http://www.w3.org/QA/Tools/css-validator/css-validator.jar"#sudo aptitude install -y ant # uncomment if you don't have antCVSROOT=:pserver:anonymous:anonymous@dev.w3.org:/sources/public cvs checkout 2002/css-validator mkdir 2002/css-validator/libTOMCAT6_VERSION='6.0.45'wget "http://www.apache.org/dist/tomcat/tomcat-6/v$TOMCAT6_VERSION/bin/apache-tomcat-$TOMCAT6_VERSION.tar.gz"tar xvf apache-tomcat-$TOMCAT6_VERSION.tar.gzmv apache-tomcat-$TOMCAT6_VERSION/lib/servlet-api.jar 2002/css-validator/lib/servlet.jarrm -rf apache-tomcat-$TOMCAT6_VERSION apache-tomcat-$TOMCAT6_VERSION.tar.gzcd 2002/css-validatorant jar# usage example: java -jar css-validator.jar "http://csszengarden.com/"That should work, at least until the next software dependency update breaks the ant build script (feel free to parameterize versions).
Hope this helps!
