如果单词在“单词”列中以超链接及其单词和ID退出，我将尝试替换句子中的单词。该表包含列ID单词和句子。下面的代码是我从一位乐于助人的同伴那里得到的。谢谢。

要替换的值是https://localhost/“ id” /“ word”如果看到id = 5的值（B数分析），则句子是https://localhost/6/ localhost / 5 / B-数字分析表，但实际值应该是https://localhost/6/ B数字分析表。
当前输出：
ID WORD SENTENCE
1 automation testing automtestingation http://localhost/2/<u>testing<u>
is popular kind of http://localhost/2/<u>testing<u>
2 testing http://localhost/3/<u>manual

6 B-number analysis table http://localhost/2/<u>testing<u>

答案 0 :(得分：2)
分两步进行：
testing映射到${2}）${2}映射到http://localhost/2/<u>testing</u>）Oracle设置：
Create table temp(
id NUMBER,
word VARCHAR2(1000),
Sentence VARCHAR2(2000)
);
insert into temp
SELECT 1,'automation testing', 'automtestingation testing is popular kind of testing' FROM DUAL UNION ALL

SELECT 3,'manual testing','this is an old method of testing' FROM DUAL UNION ALL
SELECT 4,'punctuation','automation testing,manual testing,punctuation,automanual testing-testing' FROM DUAL UNION ALL
SELECT 5,'B-number analysis','B-number analysis table' FROM DUAL UNION ALL
SELECT 6,'B-number analysis table','testing B-number analysis' FROM DUAL UNION ALL
SELECT 7,'Not Matched','testing testing testing' FROM DUAL;
合并：

更新：
在单词中转义任何特殊的正则表达式字符：
