Question

我在使用org.w3c.dom的Node.getTextContent（）时遇到了麻烦。我有以下代码块：

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

eclipse给了我The method getTextContent() is undefined for the type Node。有什么问题我不明白。

谢谢和问候。

这是pom.xml，而commons-digester需要包含org.w3c.dom的xml-apis-1.0b2。我认为这是一个依赖性问题。

Answer 1

您需要在eclipse中转到项目的属性。然后选择“Java Build Path”和“Order and Export”选项卡。在这里，您可以安排依赖项的顺序。确保您的JRE高于Maven依赖项。

Answer 2

尝试使用：

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

AFAIK在某些情况下，它比getTextContent()“更安全”。

Answer 3

我知道这是一篇较旧的帖子，但对于那些达到此目的的人，我遇到了类似的问题并使用以下步骤修复了该问题：

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

即org.w3c.dom.Node.getTextContent() is only available as of Java 1.5，但也请注意Node的声明。 xml-apis-1.0.b2.jar是有问题的。进入项目属性＆gt; Java构建路径＆gt; “订购和导出”标签，并将xml-apis-1.0.b2.jar移至顶部。

Java 1.6.0_20中的Eclipse Node.getTextContent（）
