我确信这个问题已被多次回答......但是我猜的数据有点独特。以下是我的数据集的一部分。
<?xml version="1.0" encoding="UTF-8"?>
<IOTModellerLog xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" DeviceID="7430180" ClientID="12324" FileCreationDate="2017-03-01T22:40:03" FileVersion="2" EventClassID="65535" IOTLogCreationDate="2017-03-01T12:29:54" SampleID="1" xsi:noNamespaceSchemaLocation="/opt/nds/ams_proxy/webapps/ams_proxy/WEB-INF/amsXmlSchema.xsd">
<Event EventTime="2017-02-27T18:33:58">
<IOTEvent State="PowerOn" />
</Event>
<Event EventTime="2017-02-28T08:59:03">
<DataEvent>
<Model>1</Model>
<DataType>1</DataType>
<DataValue>0301</DataValue>
</DataEvent>
</Event>
<Event EventTime="2017-02-28T08:59:13">
<DataEvent>
<Model>1</Model>
<DataType>1</DataType>
<DataValue>0401</DataValue>
</DataEvent>
</Event>
</IOTModellerLog>
我正在尝试将其转换为第一列为EventTime
的数据框。预期的格式如下:
EventTime Model DataType DataValue
2017-02-28T08:59:13 1 1 0401
2017-02-28T08:59:15 1 5 070707
我尝试了以下内容:
result <- xmlParse("demoxml.xml")
XML:::xmlAttrsToDataFrame(result["//Event"]) #This just prints only the time
xmlToDataFrame(nodes=getNodeSet(result,"//DataEvent"))[c("Model","DataType","DataValue")]
我不知道如何将EventEvent值与EventTime一起获取并将其放在data.frame中。
有人可以帮忙吗?
答案 0 :(得分:1)
我使用过这样的东西
for( i = 0; i < markers.length; i++ ) {
var position = new google.maps.LatLng(markers[i][0], markers[i][1]);
var icon = {url:"http:///".concat(markers[i][3]),
scaledSize: new google.maps.Size(20, 20), // scaled size
origin: new google.maps.Point(0,0), // origin
anchor: new google.maps.Point(0, 0) };
marker = new google.maps.Marker({
position: position,
map: map,
title: markers[i][4].toString().concat(' ').concat(markers[i][5].toString()),
icon: icon,
url:'im:<sip:'+markers[i][6]+'>'
});
var infowindow = new google.maps.InfoWindow({
content: ''
});
marker.addListener('mouseover', function() {
infowindow.setContent('<p><label>Name:</label> '+this.title+'</p>' +
'<center><button class="btn btn-primary" \n\
onclick="window.location.assign(' + this.url + ');">Call</button></center>');
infowindow.open(map, this);
});
结果如下所示
library(XML)
library(data.table)
result <- xmlParse('text_XML.xml')
result_nodes = XML::getNodeSet(result , "//IOTModellerLog/Event")
rbindlist(lapply(result_nodes,function(x) data.frame(as.list(unlist(xmlToList(x))))),use.names = TRUE, fill = TRUE)
我认为这是你可以使用的东西:)
