假设我有一个文本文件,其中的行如下:
[4/20/11 17:07:12:875 CEST] 00000059 FfdcProvider W com.test.ws.ffdc.impl.FfdcProvider logIncident FFDC1003I: FFDC Incident emitted on D:/Prgs/testing/WebSphere/AppServer/profiles/ProcCtr01/logs/ffdc/server1_3d203d20_11.04.20_17.07.12.8755227341908890183253.txt com.test.testserver.management.cmdframework.CmdNotificationListener 134
[4/20/11 17:07:27:609 CEST] 0000005d wle E CWLLG2229E: An exception occurred in an EJB call. Error: Snapshot with ID Snapshot.8fdaaf3f-ce3f-426e-9347-3ac7e8a3863e not found.
com.lombardisoftware.core.TeamWorksException: Snapshot with ID Snapshot.8fdaaf3f-ce3f-426e-9347-3ac7e8a3863e not found.
at com.lombardisoftware.server.ejb.persistence.CommonDAO.assertNotNull(CommonDAO.java:70)有没有办法轻松地将这样的数据源导入到protovis中,如果没有,那么将其解析为JSON格式的最简单方法是什么?例如,第一个条目的解析可能如下所示:
[
{
"Date": "4/20/11 17:07:12:875 CEST",
"Status": "00000059",
"Msg": "FfdcProvider W com.test.ws.ffdc.impl.FfdcProvider logIncident FFDC1003I",
},
]谢谢,大卫

Protovis本身不提供解析文本文件的任何实用程序,因此您可以选择:
JSON
您选择哪一个取决于以下几个因素:
如果您希望在Javascript中根据您提供的示例执行此操作,则可以执行以下操作:
// Assumes var text = 'your text';
// use the utility of your choice to load your text file into the
// variable (e.g. jQuery.get()), or just paste it in.
var lines = text.split(/[\r\n\f]+/),
// regex to match your log entry beginning
patt = /^\[(\d\d?\/\d\d?\/\d\d? \d\d:\d\d:\d\d:\d{3} [A-Z]+)\] (\d{8})/,
items = [],
currentItem;
// loop through the lines in the file
lines.forEach(function(line) {
// look for the beginning of a log entry
var initialData = line.match(patt);
if (initialData) {
// start a new item, using the captured matches
currentItem = {
Date: initialData[1],
Status: initialData[2],
Msg: line.substr(initialData[0].length + 1)
}
items.push(currentItem);
} else {
// this is a continuation of the last item
currentItem.Msg += "\n" + line;
}
});
// items now contains an array of objects with your datahttps://stackoverflow.com/questions/6947890
