本文整理了Java中org.apache.axiom.om.OMText类的一些代码示例，展示了OMText类的具体用法。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。OMText类的具体详情如下：
包路径：org.apache.axiom.om.OMText
类名称：OMText

OMText介绍

[英]Represents character data in an XML document. A node of this type is used to represent character data that may appear in element content as well as the prolog and epilog of a document. Note that this node type is used for normal character data, CDATA sections and ignorable whitespace. The OMNode#getType() method may be used to distinguish between these different types of character data.

By default, Axiom uses StAX parsers configured in coalescing mode. As a consequence, CDATA sections will not result in nodes of type OMNode#CDATA_SECTION_NODE nodes, but of type OMNode#TEXT_NODE(See the Javadoc of org.apache.axiom.om.util.StAXUtils for information about how to change this behavior). In addition, the object model instance will never contain two adjacent OMText siblings.

The same is not necessarily true for Axiom trees that have been built or updated programmatically or that contain nodes resulting from the expansion of an OMSourcedElement. Therefore, code that manipulates character data MUST NOT assume that text nodes are always coalesced. In particular, when extracting character data from an element, OMElement#getText()should be used instead of OMText#getText().

An OMText node stores the character data as String, char[] or a javax.activation.DataHandler. The latter is used for base64 encoded binary data.
[中]表示XML文档中的字符数据。这种类型的节点用于表示可能出现在元素内容以及文档的序言和尾声中的字符数据。请注意，此节点类型用于普通字符数据、CDATA节和可忽略的空白。OMNode#getType（）方法可用于区分这些不同类型的字符数据。
默认情况下，Axiom使用以合并模式配置的StAX解析器。因此，CDATA节不会产生OMNode#CDATA#SECTION#NODE NODE类型的节点，而是OMNode#TEXT#NODE类型的节点（有关如何更改此行为的信息，请参阅org.apache.axiom.om.util.StAXUtils的Javadoc）。此外，对象模型实例永远不会包含两个相邻的OMText同级。
对于以编程方式构建或更新的Axiom树，或者包含OMSourceElement扩展产生的节点的Axiom树，情况不一定如此。因此，操纵字符数据的代码不能假定文本节点总是合并的。特别是，从元素中提取字符数据时，应该使用OmeElement#getText（）而不是OMText#getText（）。
OMText节点将字符数据存储为字符串、char[]或javax。激活。数据处理程序。后者用于base64编码的二进制数据。
