我可以使用xslt样式表来更新网页吗？ [英] Can I use an xslt stylesheet to update a web page?
问题描述
我正在开发一个数据密集型网络应用。应用程序的核心
将执行数据库查询并构建页面。我计划将数据作为xml
并将该数据和xslt样式表提供给浏览器。这是我的
问题：用户可以请求更多数据。我想以某种方式
使用相同（或其版本）样式表来转换这个新的
数据。但这会添加到现有页面中，而不是替换它。
有一个简单的方法吗？
TIA。

添加到现有页面的内容是什么？是什么意思？
这是网络。 HTTP工作，以便你得到一个新的页面（可能是更大的
），虽然它_looks_喜欢旧的页面添加了
它，它'实际上是一个全新的页面由全新的位和
字节组成。所以从传统的HTTP视图来看，你的请求是不可能的，因为HTTP就是不能那样工作。
为了高效的设计，你应该看看在缓存服务器上的样式表虽然 - 这肯定是值得的。
然而你的请求是合理的，这些天它是
越来越有可能。看看使用AJAX的方式真的是
添加到现有页面。这取决于客户端脚本
虽然。

替代方案可能是
来源与浏览器之间的内容组合。想法是服务器内的代理或过滤器
缓存原始内容并根据需要添加新的
内容。这可以用来避免在服务器上重复昂贵的处理，同时还避免使用浏览器 -
依赖脚本。

我不清楚，对不起。是的，它将是一个AJAX应用程序，已经有很多JavaScript了。我想要的是一些JavaScript方式来转换传入的xml
。这样我只需要维护一个代码
base，将数据转换为可显示的形式。我可以使用xslt
样式表作为首字母，但必须通过JavaScript进行更新（例如获得
新记录）。

I have a data intensive web app I am developing. The core of the app
will do a db query and build a page. I plan on getting the data as xml
and feeding that and a xslt stylesheet to the browser. Here is my
question: the user can the request more data. I would like to somehow
use the same (or a version thereof) stylesheet to transform this new
data. But this is added to the existing page, not replacing it. Is
there a simple way to do this?
TIA.

What does "added to the existing page" mean?
This is the web. HTTP works so that you get a new page (which might be
bigger) and although it _looks_ like "the old page with things added to
it", it''s actually a whole new page made of entirely new bits and
bytes. So from the traditionalist HTTP view, your request is
impossible because HTTP just doesn''t work like that.
For good efficient design, you should look at caching the stylesheet on
the server though - that''s certainly worth doing.
However your request is a reasonable one and these days it''s
increasingly possible. Look at using AJAX for a way that really is
"adding to the existing page". This depends on client-side scripting
though.

An alternative could be content assembly somewhere between the
origin and the browser. The idea being that a proxy, or a filter
within the server, caches the original contents and adds new
contents as necessary. This can be used to avoid repeating
expensive processing on the server, while also avoiding browser-
dependent scripting.

I was not clear, sorry. Yes, it is going to be an AJAX app, there is
lots of JavaScript already. What I wanted was some JavaScript way to
transform the incoming xml. That way I only need to maintain one codes
base that turns the data to a displayable form. I can use a xslt
stylesheet for the initial, but would have to do the update (getting a
new record, for example) through JavaScript.
