java
Pattern pattern = Pattern.compile("<resultMap\\s+id=\"BaseResultMap\"[\s\S]+?>([\s\S]+?)</resultMap>");
Matcher m = pattern.matcher(xml);
if (m.find()) {
System.out.println(m.group());
}Pattern pattern = Pattern.compile("<resultMap\\s+id=\"BaseResultMap\"[\s\S]+?>([\s\S]+?)</resultMap>");
Matcher m = pattern.matcher(xml);
if (m.find()) {
System.out.println(m.group());
}输出
xml

<id column="id" property="id"/>
<result column="alias" property="alias" jdbcType="VARCHAR" />
<result column="name" property="name" jdbcType="VARCHAR" />

</resultMap>如果是要获取resultMap里面的节点：
java
Pattern pattern = Pattern.compile("<resultMap\\s+id=\"BaseResultMap\"[\s\S]+?>([\s\S]+?)</resultMap>");
Matcher m = pattern.matcher(xml);
if (m.find()) {
System.out.println(m.group(1));
}Pattern pattern = Pattern.compile("<resultMap\\s+id=\"BaseResultMap\"[\s\S]+?>([\s\S]+?)</resultMap>");
Matcher m = pattern.matcher(xml);
if (m.find()) {
System.out.println(m.group(1));
}
