insertNode的代码大致是这个样子(为了便于展示，对方法进行了一些整合)：
Element insert(Token.StartTag startTag) { Tag tag = Tag.valueOf(startTag.name()); Element el = new Element(tag, baseUri, startTag.attributes); stack.getLast().appendChild(el); if (startTag.isSelfClosing()) { tokeniser.acknowledgeSelfClosingFlag(); if (!tag.isKnownTag()) // unknown tag, remember this is self closing for output. see above. tag.setSelfClosing(); } else { stack.add(el); } return el;}
private void closeCell(HtmlTreeBuilder tb) { if (tb.inTableScope("td")) tb.process(new Token.EndTag("td")); else tb.process(new Token.EndTag("th")); // only here if th or td in scope}
