我用Java编写了一个解析器,用于解析文本文件中的多个功能,其思想是获取对应于相应标题的一行行。

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的所有功能,我都可以做到这一点。

当我有这个问题来了:

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“功能”块时,我的解析器将始终在末尾跳一行,因此转义了我无法获得的带有“ SUBUNIT”的行:(

这是我需要解析的文件的示例:

    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。我正在尝试在读取文件时标记文件中的当前位置,但是当我这样做时,解析无法正常进行。我在这里想念什么?

为任何帮助加油,将不胜感激:)

            // Function
        if (line.startsWith("CC   -!- FUNCTION")) {
            String data[] = line.split("CC   -!- FUNCTION:");
            function = function + data[1];
            while ((line = bReader.readLine()) != null && ( (line.startsWith("CC       ")) || (line.startsWith("CC   -!- FUNCTION")) ) ) {
                if (line.startsWith("CC       ")) {
                    String dataOther[] = line.split("CC      ");
                    function = function + dataOther[1];
                    prot.setFunction(function);
                    bReader.mark(size);

                }

                else if (line.startsWith("CC   -!- FUNCTION")) {
                    String dataOther[] = line.split("CC   -!- FUNCTION:");
                    function = function + "-!-"+ dataOther[1];
                    prot.setFunction(function);
                    bReader.mark(size);

                }
            }



            bReader.reset();
        }


        // Subunit
        if (line.startsWith("CC   -!- SUBUNIT")) {
            String data[] = line.split("CC   -!- SUBUNIT:");
            subunit = subunit  + "-|-"+ data[1];
            while ((line = bReader.readLine()) != null && ( (line.startsWith("CC       "))  ) ) {
                if (line.startsWith("CC       ")) {
                    String dataOther[] = line.split("CC      ");
                    subunit  = subunit  + dataOther[1];
                    prot.setSubunit(subunit);


                }


            }

            //bReader.reset();
        }

最佳答案

.mark()和.reset()用于读取缓冲区的更高级技术。我认为,就您而言,您只需要重新学习从文件中读取数据即可。我在您的代码中看到您有多个bReader.readLine();它将从缓冲区读取一行并每次都将其丢弃,因此通常您只需要一次.readLine,然后对其进行处理。

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();


我理解正确吗?
