ITextRenderer.setDocumentFromString(html)导致javax.xml.transform.TransformerException
提问于 2015-05-13 08:24:36
我正在用JSoup转换一些HTML。在最后的HTML被产生后，我想把它渲染成pdf文件。为此，我正在使用Flying saucer库。
我试图呈现的Html示例：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
...方法将html呈现为pdf：
private void createPdfFile(String html, String fileName) throws IOException, DocumentException {
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(html);
renderer.layout();
FileOutputStream fos = new FileOutputStream(fileName);
renderer.createPDF( fos );
fos.close();
System.out.println( "File 2: '" + fileName + "' created." );
}错误日志：

您需要用引号包装您的DTD URI --您目前是不平衡的：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">在现有代码中，您在"之前缺少了http://www.w3...

检查标记属性中的引号。我没有“标记”，这给我造成了类似的错误。
