我正在编写解析器代码来读取 .csv 文件并将其解析为 XML。这是我拥有的代码并且可以正常工作,除了我希望它跳过文件中的第一行。所以我决定设置一个 HashMap 但它似乎不起作用:
for (int i = 0; i < listOfFiles.length; i++) {
File file = listOfFiles[i];
if (file.isFile() && file.getName().endsWith(".csv")){
System.out.println("File Found: " + file.getName());//Prints the name of the csv file found
String filePath = sourcepath + "\\" + file.getName();
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
int n = 1;
Map<Integer,String> lineMap = new HashMap<Integer,String>();
int k=2;
while ((line = br.readLine()) != null) {
System.out.println(n + " iteration(s) of 1st While Loop");
lineMap.put(k, line);
fw.write(" <ASSET action=\"AddChange\">\n");
fw.write(" <HOSTNAME>\n");
hostName=line.substring(0, line.indexOf(","));
fw.append(hostName);
fw.write("</HOSTNAME>\n");
fw.write(" <HOSTID>\n");
hostID=line.substring(line.indexOf(",")+1, nthOccurrence(line, ',', 1));
fw.append(hostID);
fw.write("</HOSTID>\n");
fw.write(" <MACMODEL>\n");
machineModel=line.substring(nthOccurrence(line, ',', 1)+1, nthOccurrence(line, ',', 2));
fw.append(machineModel);
fw.write("</MACMODEL>\n");
fw.write(" <PROMODEL>\n");
processorModel=line.substring(nthOccurrence(line, ',', 2)+1, nthOccurrence(line, ',', 3));
fw.append(processorModel);
fw.write("</PROMODEL>\n");
fw.write(" <CORE>\n");
core=line.substring(nthOccurrence(line, ',', 3)+1, nthOccurrence(line, ',', 4));
fw.append(core);
fw.write("</CORE>\n");
fw.write(" <PROC>\n");
proc=line.substring(nthOccurrence(line, ',', 4)+1, nthOccurrence(line, ',', 5));
fw.append(proc);
fw.write("</PROC>\n");
fw.write(" <TIER>\n");
tier=line.substring(nthOccurrence(line, ',', 5)+1, nthOccurrence(line, ',', 6));
fw.append(tier);
fw.write("</TIER>\n");
fw.write(" <PRODNAME>\n");
productName=line.substring(nthOccurrence(line, ',', 6)+1, nthOccurrence(line, ',', 7));
fw.append(productName);
fw.write("</PRODNAME>\n");
fw.write(" <VERSION>\n");
version=line.substring(nthOccurrence(line, ',', 7)+1, nthOccurrence(line, ',', 8));
fw.append(version);
fw.write("</VERSION>\n");
fw.write(" <SCRIPTDATA>\n");
scriptData=line.substring(nthOccurrence(line, ',', 8)+1, line.length());
fw.append(scriptData);
fw.write("</SCRIPTDATA>\n");
fw.write(" </ASSET>\n");
k++;
}n++;
这是代码主要部分的一个片段。任何想法或解决方案???

您可能会考虑将
headerLine = br.readLine()
放在 while 循环之前,这样您就可以将标头与文件的其余部分分开使用。您也可以考虑使用 opencsv 进行 csv 解析,因为它可以简化您的逻辑。
