&要写成&才行

要转移，

& 要写成 &
[注意那个分号]

给你一段Code，Java的，。改改就行了。

	public static String replaceString(String str, String regex, String replacement)
	{
		if (str == null)
		{
			return null;
		}
		int index = -1;
		index = str.indexOf(regex);
		String strNew = "";
		if (index >= 0)
		{
			while (index >= 0)
			{
				strNew += str.substring(0, index) + replacement;
				str = str.substring(index + regex.length());
				index = str.indexOf(regex);
			}
			strNew += str;
			return strNew;
		}
		return str;
	}
	
	
	public static String encodeXmlString(String xml)
	{
		if (xml == null)
		{
			return "";
		}
		xml = replaceString(xml, "&", "&");
		xml = replaceString(xml, "<", "<");
		xml = replaceString(xml, ">", ">");
		xml = replaceString(xml, "'", "'");
		xml = replaceString(xml, "\"", """);
		return xml;
	}


	public static String decodeXmlString(String xmlEscaped)
	{
		xmlEscaped = replaceString(xmlEscaped, "<", "<");
		xmlEscaped = replaceString(xmlEscaped, ">", ">");
		xmlEscaped = replaceString(xmlEscaped, "'", "'");
		xmlEscaped = replaceString(xmlEscaped, """, "\"");
		String ret = replaceString(xmlEscaped, "&", "&");
		return ret;
	}
