Parsing XML data from Filebeat using Logstash

Can you try editing the xpath configuration in the filter as below:

filter {    xml     {        source => "ticket"        xpath =>         [            "/IDH_Ticket/text()", "ticketId",            "/CodeBus/text()", "codeBus",            "/CodeCh/text()", "codeCh",            "/CodeConv/text()", "codeConv",            "/Codeligne/text()", "codeLigne",            "/Date/text()", "date",            "/Heur/text()", "heure",            "/NomFR1/text()", "nomFR1",            "/NomAR1/text()", "nomAR1",            "/NomFR2/text()", "nomFR2",            "/NomAR2/text()", "nomAR2",            "/Prix/text()", "prix",            "/IDTicket/text()", "idTicket",            "/CodeRoute/text()", "codeRoute",            "/origine/text()", "origine",            "/Distination/text()", "destination",            "/Num/text()", "num",            "/Ligne/text()", "ligne",            "/requisition/text()", "requisition",            "/voyage/text()", "voyage",            "/faveur/text()", "faveur"        ]        store_xml => true        target => "doc"    }}

The xml filter won't work since the source configuration points to a field that does not exist.
There are no field ticket in your document:

{    "message" => "\t<H_Ticket>\r\n\t\t<IDH_Ticket>1</IDH_Ticket>\r\n\t\t<CodeBus>186</CodeBus>\r\n\t\t<CodeCh>5531</CodeCh>\r\n\t\t<CodeConv>5531</CodeConv>\r\n\t\t<Codeligne>12</Codeligne>\r\n\t\t<Date>20150903</Date>\r\n\t\t<Heur>1101</Heur>\r\n\t\t<NomFR1>SOUK AHAD</NomFR1>\r\n\t\t<NomAR1>??? ?????</NomAR1>\r\n\t\t<NomFR2>SOVIVA </NomFR2>\r\n\t\t<NomAR2>??????</NomAR2>\r\n\t\t<Prix>0.66</Prix>\r\n\t\t<IDTicket>1</IDTicket>\r\n\t\t<CodeRoute>107</CodeRoute>\r\n\t\t<origine>01</origine>\r\n\t\t<Distination>07</Distination>\r\n\t\t<Num>3</Num>\r\n\t\t<Ligne>107</Ligne>\r\n\t\t<requisition> </requisition>\r\n\t\t<voyage>0</voyage>\r\n\t\t<faveur> </faveur>\r\n\t</H_Ticket>",    "@version" => "1",    "@timestamp" => "2016-07-03T12:13:28.892Z",    "input_type" => "log",    "source" => "C:\\busesdata\\ticket2.xml",    "offset" => 125,    "type" => "ticket",    "count" => 1,    "fields" => nil,    "beat" => {        "hostname" => "hp-pavillion-g6",        "name" => "hp-pavillion-g6"    },    "host" => "hp-pavillion-g6",    "tags" => [        [0] "beats_input_codec_plain_applied"    ]}

You should change the xml filter to:

 xml {        source => "message"        ... }
