How to parse nagios status.dat file?

Question

I\'d like to parse status.dat file for nagios3 and output as xml with a python script. The xml part is the easy one but how do I go about parsing the file? Use multi line re

You can do something like this:

def parseConf(filename):
    conf = []
    with open(filename, 'r') as f:
        for i in f.readlines():
            if i[0] == '#': continue
            matchID = re.search(r"([\w]+) {", i)
            matchAttr = re.search(r"[ ]*([\w]+)=([\w\d]*)", i)
            matchEndID = re.search(r"[ ]*}", i)
            if matchID:
                identifier = matchID.group(1)
                cur = [identifier, {}]
            elif matchAttr:
                attribute = matchAttr.group(1)
                value = matchAttr.group(2)
                cur[1][attribute] = value
            elif matchEndID:
                conf.append(cur)
    return conf

def conf2xml(filename):
    conf = parseConf(filename)
    xml = ''
    for ID in conf:
        xml += '<%s>\n' % ID[0]
        for attr in ID[1]:
            xml += '\t%s\n' % \
                    (attr, ID[1][attr])
        xml += '\n' % ID[0]
    return xml

Then try to do:

print   conf2xml('conf.dat')
