SVG Batik根元素命名空间与请求的不匹配 [英] SVG Batik Root element namespace does not match that requested

问题描述

几周以前，它完全正常工作我的SVG，但它不知何故停止工作，我不知道原因，因为在服务器上触发的错误没有帮助。当我将svg文件传输到我的pdf时会发生这种情况：

Few weeks ago, it was working PERFECTLY my SVG, but somehow it stopped working and I don't know the cause because the error fired on the server wasn't helpful. It happens when I transfer the svg file to my pdf:

Root element namespace does not match that requested:
Requested: http://www.w3.org/2000/svg
Found: null. Stacktrace follows:

我不是这个意思，我的xml svg（在xml验证器上）网站）是有效的代码。我写的是这样的：

I don't what it means, my xml svg(on xml validator website) is valid code. I'm writing like this:

file.write('<?xml version="1.0" encoding="UTF-8"?> \n'
+ '<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> \n'
+ '<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="705px" height="1000px" viewBox="0 0 705 1000" enable-background="new 0 0 705 1000" xml:space="preserve"> \n'
+ svgimage + '\n'
+ '</svg>');

变量svgimage是一堆 g ， defs ， text ， images 等（非常大） ，像1k行一样）

The variable svgimage is a bunch of g, defs, text, images, etc (really big, like 1k of lines)

推荐答案

我有很多工作要找到xml上+ 1k行的原因这是svg创建的标签，w3无法识别，这是 clipPath 和 clip-path 并删除它们，完美运作：

I had a lot of work to find the cause over +1k of lines on my xml and It's a tag that svg created and w3 didn't recognized, which is clipPath and clip-path and by removing them, works perfectly:

<clipPath id="_ABSTRACT_RENDERER_ID_0"> //removed
...
</clipPath>

<g clip-path="url(http://mypage.com/344#_ABSTRACT_RENDERER_ID_0)"> //remove the attribute clip-path
...
</g>

不知何故，w3没有识别 url（...）只需删除它，它就可以了。而且很奇怪，它总是在那里。

Somehow, the w3 didnt recognized the url(...) by simply removing this, it works. And It's strange, it was always there.
