怎样让builder.parse()忽略DTD找不到的错误继续分析？

[popodai]

DocumentBuilderFactory factory = DocumnetBuilderFactory.newInstance();
factory.setValidating(false);
DocumentBuilder bulider = factory.newDocumentBuilder();
org.w3c.dom.Document loDoc = builder.parse(loTargetXmlFile);
DOMBuilder domBuilder = new DOMBuilder();
Documnet poDoc = domBuilder.build(loDoc);
---------------------------------------------------
执行org.w3c.dom.Document loDoc = builder.parse(loTargetXmlFile);
抛出SAXException.
是因为loTargetXmlFile中指定的DTD找不到。

现在需要即使指定的DTD找不到，也能继续分析。
应该怎么处理？？？

builder.setEntityResolver(new EntityResolver() { public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId) throws SAXException, java.io.IOException { if (publicId.equals("--myDTDpublicID--")) // this deactivates the open office DTD return new InputSource(new ByteArrayInputStream("<?xml version='1.0' encoding='UTF-8'?>".getBytes())); else return null; }});

谢谢!这个办法确实能行。
可是
myDocumentBuilder.setEntityResolver(new EntityResolver() {
public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId)
throws SAXException, java.io.IOException
{
if (publicId.equals("--myDTDpublicID--"))// this deactivates the open office DTD
return new InputSource(new ByteArrayInputStream("<?xml version='1.0' encoding='UTF-8'?>".getBytes()));
else
return null;
}
});

谢谢这个办法确实可行，可是如下。
myDocumentBuilder.setEntityResolver(new EntityResolver() {
public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId)
throws SAXException, java.io.IOException
{
System.out.println("publicId" + publicId);
if (publicId.equals("--myDTDpublicID--"))// this deactivates the open office DTD
return new InputSource(new ByteArrayInputStream("<?xml version='1.0' encoding='UTF-8'?>".getBytes()));
else
return null;
}
});

System.out.println("publicId" + publicId);会被执行3次。前两次都是null,第3次才会有
值,这是什么原因？
