有两种不同类型的 wikitext 超链接：
[[stack]]
[[heap (memory region)|heap]]
我想删除超链接但保留文本：
stack
heap
目前，我正在运行两个阶段，使用两个不同的正则表达式：
public class LinkRemover
{
private static final Pattern
renamingLinks = Pattern.compile("\\[\\[[^\\]]+?\\|(.+?)\\]\\]");
private static final Pattern
simpleLinks = Pattern.compile("\\[\\[(.+?)\\]\\]");
public static String removeLinks(String input)
{
String temp = renamingLinks.matcher(input).replaceAll("$1");
return simpleLinks.matcher(temp).replaceAll("$1");
}
}
有没有办法将两个正则表达式“融合”成一个，达到相同的结果？
如果您想检查您提出的解决方案的正确性，这里有一个简单的测试类：
public class LinkRemoverTest
{
@Test
public void test()
{
String input = "A sheep's [[wool]] is the most widely used animal fiber, and is usually harvested by [[Sheep shearing|shearing]].";
String expected = "A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing.";
String output = LinkRemover.removeLinks(input);
assertEquals(expected, output);
}
}
