使用 QString 跳过注释行
原标题:Skipping Commented Lines with QStrings

我想跳过我使用 QStrings 进行解析的文本文件中的注释行。

如何跳过任何以字符开头的线条?

这就是我目前拥有的:

     QTextStream in(&inputFile);
     QList< QStringList > lists;
     QString inputLines;

     do {
          inputLines = in.readLine();
          lists << inputLines.split("	");

        } while (!inputLines.isNull());
          .
          .
          .
最佳回答

只要使用 < a href=" "http://qt-project.org/doc/qt-4.8/qstring.html#startsOn" rel="nofollow"\\\\ string::: startsWith(QString) 来过滤处理前的线条,例如如下示例:

QStringList lines = ...;
foreach(QString line, lines)
{
    line = line.trimmed(); // if you want to ignore whitespaces at both ends
    if(!line.startsWith("#"))
        processLine(line);
}
