我想知道如何使用Cobra/Lobo工具包訪問DOM節點的CSS屬性(在本例中爲< img>節點)。我現在有的是:如何使用Cobra/Lobo HTML渲染器訪問DOM節點的屬性
UserAgentContext uacontext = new SimpleUserAgentContext();
DocumentBuilderImpl builder = new DocumentBuilderImpl(uacontext);
URL url = new URL(TEST_URI);
InputStream in = url.openConnection().getInputStream();
Reader reader = new InputStreamReader(in, "ISO-8859-1");
InputSourceImpl inputSource = new InputSourceImpl(reader, TEST_URI);
HTMLDocumentImpl d = (HTMLDocumentImpl) builder.parse(inputSource);
HTMLCollection images = d.getImages();
for (int i = 0; i < images.getLength(); i++) {
HTMLElementImpl n = (HTMLElementImpl) images.item(i);
AbstractCSS2Properties curr = n.getCurrentStyle();
System.out.println("Image " + i + ": " + curr.getPropertyValue("background-color"));
}
現在,這似乎只給我直接設置樣式 - 沒有繼承或計算樣式。我怎樣才能得到這些?
感謝
