本文整理了Java中net.sf.saxon.om.Item.getStringValue()方法的一些代码示例，展示了Item.getStringValue()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。Item.getStringValue()方法的具体详情如下：
包路径：net.sf.saxon.om.Item
类名称：Item
方法名：getStringValue

Item.getStringValue介绍

[英]Get the value of the item as a string. For nodes, this is the string value of the node as defined in the XPath 2.0 data model, except that all nodes are treated as being untyped: it is not an error to get the string value of a node with a complex type. For atomic values, the method returns the result of casting the atomic value to a string.

If the calling code can handle any CharSequence, the method #getStringValueCS should be used. If the caller requires a string, this method is preferred.
[中]以字符串形式获取项的值。对于节点，这是XPath 2.0数据模型中定义的节点的字符串值，但所有节点都被视为非类型化：获取复杂类型节点的字符串值不是错误。对于原子值，该方法返回将原子值强制转换为字符串的结果。
如果调用代码可以处理任何CharSequence，则应使用方法#getStringValueCS。如果调用方需要字符串，则首选此方法。

代码示例

/**
 * Convert the value to a string, using the serialization rules.
 * For atomic values this is the same as a cast; for sequence values
 * it gives a space-separated list. For QNames and NOTATIONS, or lists
 * containing them, it fails.
 */
/*@NotNull*/
public String getStringValue() {
  return item == null ? "" : item.getStringValue();
}
