Question

我单独使用xml，我想在名为scl

的标记之外添加标记

所以例如

<documents>
<rnl></rnl>
<snl></snl>
<scl>This is scl</scl>
</documents>

所以<scl>This is scl</scl＆gt;将转换为<credit><scl>This is scl</scl></credit> 我如何修改以下来实现这一目标？到目前为止我已经尝试过。

String content5 = "<scl>this is scl</scl>";
System.out.println(content5.replaceAll("^(?:&lt;scl&gt;)(?:.*?)(?:&lt;/scl&gt;)", "<credit>$1</credit>" ));

Answer 1

一种方法是这样做：

String content5 = "<scl>this is scl</scl>";
System.out.println(content5.replace("<scl>", "<credit><scl>").replace("</scl>", "</scl></credit>"));

Answer 2

试试这个

    StringBuilder sb = new StringBuilder(content5);

    sb.insert(sb.indexOf("<scl>"), "<credit>");
    sb.insert(sb.indexOf("</scl>") + "</scl>".length(), "</credit>");

    String result = sb.toString();

Answer 3

你走了：

String content5 = 
    "<scl>this is scl</scl>\n" +
    "<blah>this isn't</blah>\n" +
    "<scl>this is scl</scl>\n" +
    "<blah>this isn't</blah>\n";
System.out.println(content5.replaceAll("(?:<scl>)(?:.*?)(?:</scl>)", "<credit>$0</credit>" ));

输出：

<credit><scl>this is scl</scl></credit>
<blah>this isn't</blah>
<credit><scl>this is scl</scl></credit>
<blah>this isn't</blah>
