求解一个HtmlParser的一个抽取实例

Question

想过滤到一些table中如下含有的table

xxxxx

我写的一个filter：
NodeFilter tablefilter = new AndFilter(new TagNameFilter("td"),new HasAttributeFilter("class", "f"));
NodeFilter fontfilter = new AndFilter(new TagNameFilter("font"),new HasAttributeFilt("size", "-1"));
fontfilter = new AndFilter(fontfilter, new HasAttributeFilter("color", "#0000cc"));

tablefilter = new AndFilter(tablefilter, new HasChildFilter(new NotFilter(fontfilter)));

NodeList list = parser.parse(tablefilter);

不知道哪里不对，过滤不掉，请教高手。

[code="java"]
// tablefilter = new AndFilter(tablefilter, new HasChildFilter(new NotFilter(fontfilter)));

// 改为
tablefilter = new AndFilter(tablefilter, new NotFilter(new HasChildFilter(fontfilter)))

// 不过你上面的那段代码, 只能过滤不含的td
