我正在尝试解析国际象棋PGN文件，但是没有设法获取多个动作和标签的所有实例。
我已经this regex了，并添加了两个捕获组名称：tag和move，这引导我进入下面的一个：
private val pgnRegex = """(?<pgnGame>\s*(?<tag>\[\s*(?<tagName>\w+)\s*"(?<tagValue>[^"]*)"\s*\]\s*)*(?<move>(?<moveNumber>\d+)(?<moveMarker>\.|\.{3})\s*(?<moveValue>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?)(?:\s*(?<moveValue2>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?))?\s*(?:\(\s*(?<variation>(?:(?<varMoveNumber>\d+)(?<varMoveMarker>\.|\.{3})\s*(?<varMoveValue>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?)(?:\s*(?<varMoveValue2>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?))?\s*(?:\((?<varVariation>.*)\)\s*)?(?:\{(?<varComment>[^\}]*?)\}\s*)?)*)\s*\)\s*)*(?:\{(?<comment>[^\}]*?)\}\s*)?)*(?<endMarker>1\-?0|0\-?1|1/2\-?1/2|\*)?\s*)""".r
我试图使用以下对象解析Pgn：
package com.loloof64.scala.pgn_to_pictures.pgn_parsing
import java.io.File
import scala.io.Source
object PgnReader {
def parseFile(inputFile:File) = {
val pgnStream = Source.fromFile(inputFile)
val pgnStr = pgnStream.mkString
pgnRegex.findAllIn(pgnStr).matchData.foreach{
currMatchData => if (!currMatchData.toString.isEmpty) {
currMatchData.subgroups.foreach { currGroup => println(s"Group id => ${currGroup}") }
}
}
pgnStream.close
}
/* thanks to Siderite : http://regexlib.com/REDetails.aspx?regexp_id=3355
* Adapted by Laurent Bernabe : added some capturing groups (tag and move) */
private val pgnRegex = """(?<pgnGame>\s*(?<tag>\[\s*(?<tagName>\w+)\s*"(?<tagValue>[^"]*)"\s*\]\s*)*(?<move>(?<moveNumber>\d+)(?<moveMarker>\.|\.{3})\s*(?<moveValue>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?)(?:\s*(?<moveValue2>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?))?\s*(?:\(\s*(?<variation>(?:(?<varMoveNumber>\d+)(?<varMoveMarker>\.|\.{3})\s*(?<varMoveValue>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?)(?:\s*(?<varMoveValue2>(?:[PNBRQK]?[a-h]?[1-8]?x?(?:[a-h][1-8]|[NBRQK])(?:\=[PNBRQK])?|O(-?O){1,2})[\+#]?(\s*[\!\?]+)?))?\s*(?:\((?<varVariation>.*)\)\s*)?(?:\{(?<varComment>[^\}]*?)\}\s*)?)*)\s*\)\s*)*(?:\{(?<comment>[^\}]*?)\}\s*)?)*(?<endMarker>1\-?0|0\-?1|1/2\-?1/2|\*)?\s*)""".r
