当我在这个方法中解析我的xml文件(变量f)时,我收到一个错误
C:\ Documents and Settings\joe\Desktop\aicpcudev\OnlineModule\map.dtd(系统找不到指定的路径)
我知道我没有dtd,也不需要它.如何在忽略DTD引用错误的同时将此File对象解析为Document对象？
private static Document getDoc(File f, String docId) throws Exception{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(f);
return doc;
}
我正在使用Java 6.我想解析我知道格式正确的XHTML.因此,我不想对文档中引用的DTD或其他模式进行任何验证.但是,我无法弄清楚如何关闭验证.我有
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
final DocumentBuilder b = factory.newDocumentBuilder();
final InputSource s = new InputSource(new StringReader(str));
org.w3c.dom.Document result = b.parse(s);
但我仍然在最后一行得到例外......

at …我已经按照这篇文章使用FlyingSaucer将XHTML转换为PDF,它很棒,但有一个主要的垮台......它的速度非常慢!
我发现从XHTML渲染PDF需要1到2分钟,无论该页面有多简单.
基本代码:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import org.xhtmlrenderer.pdf.ITextRenderer;
import com.lowagie.text.DocumentException;
public class FirstDoc {
public static void main(String[] args) throws IOException, DocumentException {
String inputFile = "firstdoc.xhtml";
String url = new File(inputFile).toURI().toURL().toString();
String outputFile = "firstdoc.pdf";
OutputStream os = new FileOutputStream(outputFile);
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(url);
renderer.layout();
renderer.createPDF(os);
os.close();
}
}
