你真的认为你的

数据的XML表示是否导致显示速度慢？我宁愿

猜你的显示器的Java实现是否要归咎于
。

二进制XML是否可能，或者我不应该使用XML方法。也许它甚至没有意义，我应该避免使用SVG。

I have written a Java application which generates lots (150 x 150)
of Scaleable Vector Graphics (SVG), which is a 2D XML application, <rect>s.
The problem is that it takes about 10 seconds to display the frame. I need
to approach real-time display if possible. So I thought a binary representation
of the data would speed it up.
Do you really think that the XML representation of your
data is responsible for the slow display ? I would rather
guess that your Java implementation of the display is to
be blamed.
Is binary XML a possibility, or should I not use an XML approach. Maybe it
doesn''t even make sense and I should avoid SVG.

这里已经多次讨论过Binary XML。

看起来微软会在他们的新MS Word应用程序发布时设置一个标准用于存储

XML。

请记住，解压缩二进制文件需要更多时间。


我敢打赌，你的应用程序的瓶颈是SVG，

它的解释和显示过程的其余部分。

Binary XML has been talked about several times here.
It looks like Microsoft will set a standard for storing
XML binarily when their new MS Word application is released.
Remember that uncompressing a binary needs even more time.

I bet that the bottleneck in your application is SVG,
its interpretation and the rest of the display process.

I am sort of new to XML and SVG. So if this has been addressed before please
be patient and/or just point me to a URL.

Any advice is appreciated.

Thank you.

你不能在xml文件中插入二进制数据，但你可以定义extern

实体，或者您可以使用Unicode对数据进行编码并直接将其插入到xml中（如果使用模式，可能会发现一些问题）

you can''t insert binary data in xml file, but you can define extern
Entity, or you can use Unicode to encode the data and insert it directly
to xml (you could find some problems if you use schema)

SVG仍然很早，但是...


你做过剖析了吗？你是否认为延迟是在XML

解析器中？

SVG is still early, but...

Did you do an profiling? Are you assuming that the delay is in the XML
parser?
