Java RegEx 替换开始和结束部分匹配特定模式的字符串

Question

嗨，我需要在 java 中编写一个正则表达式，它将找到以下所有实例:

wsp:rsidP="005816D6" wsp:rsidR="005816D6" wsp:rsidRDefault="005816D6" 

XML 字符串中的属性并将其删除:

所以我需要删除所有以 wsp:rsid 开头的属性并以双引号结尾 ( " )

对此的想法:

String str = xmlstring.replaceAll("wsp:rsid/w", "");

String str = xmlstring.replaceAll("wsp:rsid[]\\"", "");

Answer 1

xmlstring.replaceAll( "wsp:rsid\\w*?=\".*?\"", "" );

这在我的测试中有效...

public void testReplaceAll() throws Exception {
    String regex = "wsp:rsid\\w*?=\".*?\"";

    assertEquals( "", "wsp:rsidP=\"005816D6\"".replaceAll( regex, "" ) );
    assertEquals( "", "wsp:rsidR=\"005816D6\"".replaceAll( regex, "" ) );
    assertEquals( "", "wsp:rsidRDefault=\"005816D6\"".replaceAll( regex, "" ) );
    assertEquals( "a=\"1\" >", "a=\"1\" wsp:rsidP=\"005816D6\">".replaceAll( regex, "" ) );
    assertEquals(
            "bob   kuhar",
            "bob wsp:rsidP=\"005816D6\" wsp:rsidRDefault=\"005816D6\" kuhar".replaceAll( regex, "" ) );
    assertEquals(
            " keepme=\"yes\" ",
            "wsp:rsidP=\"005816D6\" keepme=\"yes\" wsp:rsidR=\"005816D6\"".replaceAll( regex, "" ) );
    assertEquals(
            "<node a=\"l\"  b=\"m\"  c=\"r\">",
            "<node a=\"l\" wsp:rsidP=\"0\" b=\"m\" wsp:rsidR=\"0\" c=\"r\">".replaceAll( regex, "" ) );
    // Sadly doesn't handle the embedded \" case...
    // assertEquals( "", "wsp:rsidR=\"hello\\\"world\"".replaceAll( regex, "" ) );
}
