$使用dom4j可解析 返回&#x等字样的 html转义字符

如果以GET或POST请求某个系统返回,带有 $#x 那很有可能是axis服务器返回的.
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><validateInvoiceResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><validateInvoiceReturn xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">{"returncode":"10006","returnmsg":"未获取到交易机构信息","fpdm":"null","fphm":"null","kprq":"null"}
</validateInvoiceReturn></validateInvoiceResponse></soapenv:Body></soapenv:Envelope>
实际内容:
{"returncode":"10006","returnmsg":"未获取到交易机构信息","fpdm":"null","fphm":"null","kprq":"null"}
参考 http://www.iteye.com/problems/73011
$$$$$ 使用dom4j可解析它
public static void main(String[] args) throws Exception {
String retXml = readStringFromFile("d://a.txt","GBK");//你刚得到的返回报文
Document document = DocumentHelper.parseText(retXml);
OutputFormat format = OutputFormat.createPrettyPrint();
StringWriter sw = new StringWriter();
XMLWriter xw = new XMLWriter(sw, format);
xw.setEscapeText(false);
xw.write(document);
xw.flush();
String finalRetXml = sw.toString();
System.out.println("最终返回报文:\n"+finalRetXml);
}
最终得到:
文件 d://a.txt存在与否?: true
读到的文件内容如下:
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><validateInvoiceResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><validateInvoiceReturn xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">{"returncode":"10006","returnmsg":"未获取到交易机构信息","fpdm":"null","fphm":"null","kprq":"null"}</validateInvoiceReturn></validateInvoiceResponse></soapenv:Body></soapenv:Envelope>
最终返回报文:
<?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<validateInvoiceResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<validateInvoiceReturn xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="soapenc:string">{"returncode":"10006","returnmsg":"未获取到交易机构信息","fpdm":"null","fphm":"null","kprq":"null"}</validateInvoiceReturn>
</validateInvoiceResponse>
</soapenv:Body>
</soapenv:Envelope>
