Question

我在java中编写了一个解析器，它解析了文本文件中的几个特性。我们的想法是得到一个与相应标题相对应的行块。

例如，如果我有这个：

CC   -!- FUNCTION: Adapter protein implicated in the regulation of a large
CC       spectrum of both general and specialized signaling pathways. Binds ...

我需要得到这个：

Function :  Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds ....

对于该类型的文本文件中的所有功能，我可以毫无问题地执行此操作。

当我有这个问题时，问题出现了：

CC   -!- FUNCTION: Adapter protein implicated in the regulation of a large
CC       spectrum of both general and specialized signaling pathway ...
CC   -!- SUBUNIT: Homodimer. Interacts with SAMSN1 and PRKCE (By
CC       similarity). Interacts with SSH1 and TORC2/CRTC2. Interacts ..

当我完成块＆＃34;功能＆＃34;时，我的解析器总是会跳到最后一行，然后通过＆＃34; SUBUNIT＆＃34;我不能再得到了：（

以下是我需要解析的文件示例：

    CC   -!- FUNCTION: Adapter protein implicated in the regulation of a large
    CC       spectrum of both general and specialized signaling pathways. Binds...
    CC   -!- SUBUNIT: Homodimer. Interacts with SAMSN1 and PRKCE (By
    CC       similarity). Interacts with SSH1 and TORC2/CRTC2. Interacts with ...
    CC   -!- SUBUNIT: Homodimer. Interacts with SAMSN1 and PRKCE salut(By
    CC       similarity). Interacts with SSH1 and TORC2/CRTC2. salutInteracts with
    CC   -!- INTERACTION:
    CC       Q76353:- (xeno); NbExp=3; IntAct=EBI-359815, EBI-6248077;
    CC       Q9P0K1-3:ADAM22; NbExp=2; IntAct=EBI-359815, EBI-1567267; ...
    CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Melanosome. Note=Identified by
    CC       mass spectrometry in melanosome fractions from stage I to stage
    CC       IV. ....

这是我写的一部分。我在阅读时试图标记文件中的当前位置，但是当我这样做时，解析并不能很好地工作。我在这里错过了什么？

                    prot.setSubunit(subunit);

            }

            //bReader.reset();
        }

.mark（）和.reset（）用于从缓冲区读取的更高级技术。我认为在你的情况下你只需要梳理一下从文件中读取数据。我在你的代码中看到你有多个bReader.readLine（）;这将从缓冲区读取一行并每次丢弃它，所以通常你只需要.readLine一次，然后处理它。

BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
   if (line.startsWith("CC   -!- FUNCTION")) {
      String line2 = br.readLine();
      //do some stuff
   }
   if (line.startsWith("CC   -!- SUBUNIT")) {
      String line2 = br.readLine();
      //do some stuff
   }
}
br.close();

我正确理解你了吗？
