正则表达式解析html

来源于网络，java正则表达式过滤html文档，仅作参考：

public String HtmlToTextGb2312(String inputString )
{
String htmlStr = inputString; //含html标签的字符串
String textStr ="";
Pattern p_script;
Matcher m_script;
Pattern p_style;
Matcher m_style;
Pattern p_html;
Matcher m_html;
Pattern p_houhtml;
Matcher m_houhtml;
Pattern p_spe;
Matcher m_spe;
Pattern p_blank;
Matcher m_blank;
Pattern p_table;
Matcher m_table;
Pattern p_enter;
Matcher m_enter;

try {
String regEx_script = "<[\\s]*?script[^>]*?>[\\s\\S]*?<[\\s]*?\\/[\\s]*?script[\\s]*?>";
//定义script的正则表达式.
String regEx_style = "<[\\s]*?style[^>]*?>[\\s\\S]*?<[\\s]*?\\/[\\s]*?style[\\s]*?>";
//定义style的正则表达式.
String regEx_html = "<[^>]+>";
//定义HTML标签的正则表达式
String regEx_houhtml = "/[^>]+>";
//定义HTML标签的正则表达式
String regEx_spe="\\&[^;]+;";
//定义特殊符号的正则表达式
String regEx_blank=" +";
//定义多个空格的正则表达式
String regEx_table="\t+";
//定义多个制表符的正则表达式
String regEx_enter="\n+";
//定义多个回车的正则表达式

p_script = Pattern.compile(regEx_script,Pattern.CASE_INSENSITIVE);
m_script = p_script.matcher(htmlStr);
htmlStr = m_script.replaceAll(""); //过滤script标签

p_blank = Pattern.compile(regEx_blank,Pattern.CASE_INSENSITIVE);

}catch(Exception e)
{
System.err.println("Html2Text: " + e.getMessage());
}

return textStr;//返回文本字符串
}
