Java中的Eclipse Node.getTextContent（）1.6.0_20

Question

我正面臨着org.w3c.dom的Node.getTextContent（）的問題。我有以下代碼塊：

String name = document.getElementsByTagName("name").item(0).getTextContent(); 

和日食給我The method getTextContent() is undefined for the type Node。我不明白的是什麼問題。

感謝和問候。

這是pom.xml中和公共沼氣池需要XML的API-1.0b2包含org.w3c.dom中。我認爲這是一個依賴問題。

Answer 1

你需要去eclipse項目的屬性。然後選擇「Java Build Path」並點擊「訂購和導出」。在這裏你可以安排依賴關係的順序。確保您的JRE比Maven依賴關係更高。

Answer 2

嘗試使用：

document.getElementsByTagName("name").item(0).getFirstChild().getNodeValue(); 

據我所知它的 「安全」 的方式比在某些情況下getTextContent()。

Answer 3

我知道這是一個老帖子，但任何人誰達到這一點，我也有類似的問題，並使用指定的步驟固定它：

http://mergetag.com/the-method-gettextcontent-is-undefined-for-the-type-node/

也就是說，org.w3c.dom.Node.getTextContent() is only available as of Java 1.5還要注意的聲明Node。 xml-apis-1.0.b2.jar是有問題的。進入項目Properties> Java Build Path> Order and Export選項卡，並將xml-apis-1.0.b2.jar移至頂部。
