本文整理了Java中org.w3c.dom.Node.getTextContent()方法的一些代码示例，展示了Node.getTextContent()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Node.getTextContent()方法的具体详情如下：
包路径：org.w3c.dom.Node
类名称：Node
方法名：getTextContent

Node.getTextContent介绍

[英]This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed and the returned string does not contain the white spaces in element content (see the attribute Text.isElementContentWhitespace). Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
The string returned is made of the text content of this node depending on its type, as defined below: Node typeContentELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODEconcatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the node has no children.TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODEnodeValueDOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODEnull
[中]此属性返回此节点及其子节点的文本内容。将其定义为null时，将其设置为无效。在设置时，此节点可能具有的所有可能的子节点都将被删除，如果新字符串不为空或null，则替换为包含此属性设置为的字符串的单个Text节点。
获取时，不执行序列化，返回的字符串不包含任何标记。不执行空白规范化，并且返回的字符串不包含元素内容中的空白（请参见属性[$3$]）。类似地，在设置时，也不执行解析，输入字符串被视为纯文本内容。
返回的字符串由该节点的文本内容组成，具体取决于其类型，定义如下：节点类型ContentElement\u节点、属性节点、实体节点、实体引用节点、文档片段节点每个子节点的textContent属性值的链接，不包括注释节点和处理指令节点。如果节点没有子节点，则为空字符串。文本节点、CDATA节点、节节点、注释节点、处理节点、指令节点nodeValue文档节点、文档类型节点、符号节点null
