Question

我试图解析名为1.svg的以下svg文件：

<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 16.0.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     width="841.89px" height="595.28px" viewBox="0 0 841.89 595.28" enable-background="new 0 0 841.89 595.28" xml:space="preserve">
<g id="Layer_2">
</g>
<g id="Layer_1">
    <line fill="none" stroke="#ED1C24" stroke-miterlimit="10" x1="103.667" y1="105.667" x2="126.667" y2="95"/>

</svg>

使用以下java程序。

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;

public class Test {

    public static void main(String[] args){
        try {
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            Document doc = dBuilder.parse("1.svg");

        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}

由于某些原因，我无法理解我得到了

我尝试使用File类打开文件，但它确实有效。你能给我一些帮助吗？谢谢！

您的SVG文件引用了正在加载的DTD。

您可以关闭DTD加载：

dbFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

也许

dbFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
