ASTM标准协议字符串的正则表达式是什么?
"P|1||123456||^|||U" + ProtocolASCII.LF
+ "O|1||138||||||||||||O" + ProtocolASCII.LF
+ "R|1|^^^BE(B)||mmol/L||C||||||20150819144937" + ProtocolASCII.LF
+ "R|2|^^^BEecf||mmol/L||C" + ProtocolASCII.LF
+ "R|3|^^^Ca++|1.17|mmol/L" + ProtocolASCII.LF
ProtocolASCII.LF = '\n'
。我正在编写String parser 以从此String中提取数据。
我基于\n
拆分了String,现在我需要解析每个String来提取数据。
是否有任何正则表达式,以便我可以映射并获得所需的结果?
字符串P|1||123456||^|||U" + ProtocolASCII.LF
显示患者编号,其中 P 表示患者标签或患者信息, 123456 是患者编号。
对于字符串R|3|^^^Ca++|1.17|mmol/L" + ProtocolASCII.LF
,是进行实验室测试的结果。 R 表示结果, ^^^ Ca ++ 表示结果的名称, 1.17 是结果值 mmol / L 是单位。
目前我正在解析字符串,如:
String[] resultArray = dataString.split("[\\r\\n]+");
HashMap<String, Object> resultData = new HashMap<>();
List<Result> sampleResults = new ArrayList<>();
for (String res : resultArray) {
//Get first character of String
char startChar = res.charAt(0);
switch (startChar) {
case ProtocolASCII.STX:
//Handle Header information. This is special case
if (res.charAt(2) == ProtocolASCII.Alphabet.H
|| res.charAt(1) == ProtocolASCII.Alphabet.H) {
resultData.put(Key.MACHINE_INFO, getHeaderInfo(res));
//System.out.println(res.charAt(2));
}
break;
case ProtocolASCII.Alphabet.P:
resultData.put(Key.PATIENT, getPatientInfo(res));
break;
case ProtocolASCII.Alphabet.O:
resultData.put(Key.ORDER, getOrderInfo(res));
break;
case ProtocolASCII.Alphabet.R:
sampleResults.add(getResultInfo(res));
break;
case ProtocolASCII.Alphabet.L:
// TODO - Handle end of line
break;
}
}
这是我完整的ASTM协议字符串:
/**
* Sample string
*/
public static final String MACHINE_STRING_ASTM = ProtocolASCII.STX + "1H|\\^&|||GEM 3000^5.6.1 ^21152^^023665^2.4|||||||||20150819154754" + ProtocolASCII.LF
+ "P|1||322061||^|||U" + ProtocolASCII.LF
+ "O|1||138||||||||||||O" + ProtocolASCII.LF
+ "R|1|^^^BE(B)||mmol/L||C||||||20150819144937" + ProtocolASCII.LF
+ "R|2|^^^BEecf||mmol/L||C" + ProtocolASCII.LF
+ "R|3|^^^Ca++|1.17|mmol/L" + ProtocolASCII.LF
+ "R|4|^^^Ca++(7.4)||mmol/L||C" + ProtocolASCII.LF
+ "R|5|^^^HCO23-||mmol/L||C" + ProtocolASCII.LF
+ "R|6|^^^HCO3std||mmol/L||C" + ProtocolASCII.LF
+ "R|7|^^^K+|5.0|mmol/L" + ProtocolASCII.LF
+ "R|8|^^^Na+|140|mmol/L" + ProtocolASCII.LF
+ "R|9|^^^SO2c||%||C" + ProtocolASCII.LF
+ "R|10|^^^TCO2||mmol/L||C" + ProtocolASCII.LF
+ "R|11|^^^THbc||g/dL||C" + ProtocolASCII.LF
+ "R|12|^^^Temp|37.0|C" + ProtocolASCII.LF
+ "L|1" + ProtocolASCII.EOT;
我可以使用Regular Expressions提取数据吗?
如果需要进一步的信息,请告诉我。

您可以尝试使用R和P:
(?:^(R)\|(\d+)\|\^*([^|]*)\|([^|]*)\|(?:([^|]*)\|)?.*$)|(?:^(P)\|(\d+)\|\|(\d+).*$)
试试这个:
final String regex = "(?:^(R)\\|(\\d+)\\|\\^*([^|]*)\\|([^|]*)\\|(?:([^|]*)\\|)?.*$)|(?:^(P)\\|(\\d+)\\|\\|(\\d+).*$)";
final String string = "P|1||322061||^|||U \n"
+ "O|1||138||||||||||||O \n"
+ "R|1|^^^BE(B)||mmol/L||C||||||20150819144937 \n"
+ "R|2|^^^BEecf||mmol/L||C \n"
+ "R|3|^^^Ca++|1.17|mmol/L \n"
+ "R|4|^^^Ca++(7.4)||mmol/L||C \n"
+ "R|5|^^^HCO23-||mmol/L||C \n"
+ "R|6|^^^HCO3std||mmol/L||C \n"
+ "R|7|^^^K+|5.0|mmol/L \n"
+ "R|8|^^^Na+|140|mmol/L \n"
+ "R|9|^^^SO2c||%||C \n"
+ "R|10|^^^TCO2||mmol/L||C \n"
+ "R|11|^^^THbc||g/dL||C \n"
+ "R|12|^^^Temp|37.0|C\n";
final Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE | Pattern.MULTILINE);
final Matcher matcher = pattern.matcher(string);
while (matcher.find()) {
//System.out.println("Full match: " + matcher.group(0));
if(matcher.group(1)!=null && matcher.group(1).equalsIgnoreCase("R"))
{
System.out.println("Result NO:"+matcher.group(2));
System.out.println("Component:"+matcher.group(3));
System.out.println("value:"+matcher.group(4));
System.out.println("unit:"+matcher.group(5));
System.out.println("##############################");
}
else if(matcher.group(6)!=null && matcher.group(6).equalsIgnoreCase("P"))
{
System.out.println("Patient :"+matcher.group(7));
System.out.println("Patient Number:"+matcher.group(8));
System.out.println("##############################");
}
}
