本文介绍了麻烦声明命名空间的工作的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我试图获得用外部css编写的命名空间(实际上是两个单独的文件)。当我在浏览器上运行该文件时,它不会使用声明的名称空间。我认为这个文件正在调用css文件,但它没有应用命名空间风格。 $ b HTML <!DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/ TR / XHTML1 / DTD / XHTML1-transitional.dtd> <?xml version =1.0encoding =utf-8?> xmlns:mov =http://www.superstarmovies.com /电影 xmlns =http://www.w3.org/1999/xhtml> < head> < meta http-equiv =Content-Typecontent =application / xhtml + xml; charset = utf-8/> < title>超级明星电影:本月之星< / title> < link rel =stylesheethref =movies.csstype =text / css?> < link rel =stylesheethref =actors.csstype =text / css?> < link rel =stylesheethref =superstar.csstype =text / css/> < / head> < body> < div id =heading>< img src =logo.gifalt =Superstar Movies/>< / div> < div id =main> < h1>本月之星< / h1> < h3>由我们的精选明星制作的电影!< / h3> < act:actors> < act:actor> < act:name> Halle Berry< / act:name> < act:date> 1966年8月14日< / act:date> < act:出生地>克利夫兰,俄亥俄州< / act:birthplace> < mov:movie genre =actionstar =Halle Berry> < mov:name>猫女< / mov:name> < mov:date>(2004)< / mov:date> < mov:length> 104分钟< / mov:length> < / mov:movie> < mov:movie genre =horrorstar =Halle Berry> < mov:name> Gothika< / mov:name> < mov:date>(2003)< / mov:date> < mov:长度> 98分钟< / mov:长度> < / mov:movie> < mov:movie genre =dramastar =Halle Berry> < mov:name> Monster& Ball< / mov:name> < mov:date>(2001)< / mov:date> < mov:length> 111分钟< / mov:length> < / mov:movie> < mov:movie genre =fantasystar =Halle Berry> < mov:name> X-Men< / mov:name> < mov:date>(2000)< / mov:date> < mov:length> 104分钟< / mov:length> < / mov:movie> < mov:movie genre =romancestar =Halle Berry> < mov:name>丛林发烧< / mov:name> < mov:date>(1991)< / mov:date> < mov:length> 132分钟< / mov:length> < / mov:movie> < / act:actor> < act:actor> < act:name> Tom Hanks< / act:name> < act:date> 1956年7月9日< / act:date> &Concord,California< / act:birthplace> < mov:movie genre =dramastar =Tom Hanks> < mov:name>如果您可以,赶上我< / mov:name> < mov:date>(2002)< / mov:date> < mov:length> 141分钟< / mov:length> < / mov:movie> < mov:movie genre =adventurestar =Tom Hanks> < mov:name>抛出< / mov:name> < mov:date>(2000)< / mov:date> < mov:length> 143分钟< / mov:length> < / mov:movie> < mov:movie genre =actionstar =Tom Hanks> < mov:name>储存私人瑞恩< / mov:name> < mov:date>(1998)< / mov:date> < mov:length> 170分钟< / mov:length> < / mov:movie> < mov:movie genre =adventurestar =Tom Hanks> < mov:name> Apollo 13< / mov:name> < mov:date>(1995)< / mov:date> < mov:length> 140分钟< / mov:length> < / mov:movie> < mov:movie genre =comedystar =Tom Hanks> < mov:name> Forrest Gump< / mov:name> < mov:date>(1994)< / mov:date> < mov:length> 142分钟< / mov:length> < / mov:movie> < mov:movie genre =dramastar =Tom Hanks> < mov:name>费城< / mov:name> < mov:date>(1993)< / mov:date> < mov:length> 125分钟< / mov:length> < / mov:movie> < mov:movie genre =comedystar =Tom Hanks> < mov:name> Big< / mov:name> < mov:date>(1988)< / mov:date> < mov:length> 104分钟< / mov:length> < / mov:movie> < / act:actor> < / act:actors> < / div> <地址> Superstar Movies&#183; 123 Moviestar Lane&#183;好莱坞,佛罗里达州12345 < / address> < / body> < / html> CSS @namespace acthttp://www.superstarmovies.com/actors; act | actor {display:block; font-family:Arial,Helvetica,sans-serif; margin-bottom:20pt} act | name,act | date {display:block} act | name {font-size:14pt;颜色:DarkRed; font-style:bold} act | date,act | birthplace {display:inline; font-style:italic; color:DarkRed} act | birthplace {padding-left:0.5em} @namespace movhttp://www.superstarmovies.com/movies; mov | movie {display:block; font-family:Arial,Helvetica,sans-serif} mov | name,mov |日期,mov |长度{display:inline} $ b $ mov | name {font-风格:粗体;颜色:#003;} mov | length {font-style:italics;填充左边:0.5em} 想法? 您的标记格式不正确:>解决方案 您的XML声明应该先出现,然后是您的文档类型声明: <?xml version =1.0encoding =utf-8?> <!DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional。 DTD> 您的一些< link /> 标签没有正确关闭,它们应该是: < link rel =stylesheethref = movies.csstype =text / css/> < link rel =stylesheethref =actors.csstype =text / css/> application / xhtml + xml 服务器。典型的服务器不知道你在为XHTML服务,所以他们将它们作为 text / html 来发送。浏览器将无法将 text / html 文件视为XML,因此它们不会将CSS应用于您的自定义XML元素。 如果您使用PHP,只需将它添加到XHTML文件的顶部即可: $ b <?php header('Content-Type:application / xhtml + xml'); ?> 或者在ASP中添加: <%Response.ContentType =application / xhtml + xml; %GT; 您还应该有一个伴随的元标记,但您的页面无需验证,浏览器无论如何忽略它: < meta http-equiv =Content-Typecontent =application / xhtml + xml; charset = utf-8/> 您可以在UA上将XHTML视为HTML标签汤, https://stackoverflow.com/a/8871965/106224\">这个答案,以更好地理解这一点。 在您的CSS中: $ b font-weight:bold ,而不是 font-style:bold 。 font-style :斜体,而不是 font-style:italics 。 确保您的 @namespace 语句放置在样式表的开头。从规范: 任何 @namespace 规则都必须遵循所有@charset和@import规则,并且在所有其他不被忽略的规则和规则集之前在样式表中。 但是,尽管如此,为什么不把演员和电影放入自己的XML文件中,然后使用XSLT将它们转换为熟悉的实际的XHTML ??I am trying to get namespaces written in an external css (two separate files actually). When I run the file on my browser it will not use the declared namespaces.

Typical servers don't know that you're serving XHTML, so they send them as text/html instead. Browsers won't be able to treat text/html files as XML, so they won't apply CSS to your custom XML elements.If you work with PHP, it's simply a matter of adding this to the very top of your XHTML file:<?php header('Content-Type: application/xhtml+xml'); ?>Or in ASP, add this:<% Response.ContentType = "application/xhtml+xml"; %>You should also have an accompanying meta tag, but it's not necessary for your page to validate, and browsers ignore it anyway:<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />You can find a short history lesson on UAs treating XHTML as HTML tag soup in this answer to better understand this.In your CSS:It's font-weight: bold, not font-style: bold.It's font-style: italic, not font-style: italics.Make sure that your @namespace statements are placed at the beginning of your stylesheets. From the spec: Any @namespace rules must follow all @charset and @import rules and precede all other non-ignored at-rules and rule sets in a style sheet.But with all that said, why aren't you placing your actors and movies into their own XML files, then transforming them using XSLT into familiar, actual XHTML? 这篇关于麻烦声明命名空间的工作的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
