Golang XML attribute and value

go, xml

Solution

I don't think you can make the XML parsing work like that. Here is the best I could come up with (run it on the playground)

var data = `<HostProperties>
<tag name="HOST_END">Thu Feb 20 12:38:24 2014</tag>
<tag name="patch-summary-total-cves">4</tag>
<tag name="cpe-1">cpe:/a:openbsd:openssh:5.6 -&gt; OpenBSD OpenSSH 5.6</tag>
<tag name="cpe-0">cpe:/o:vmware:esx_server</tag>
<tag name="system-type">hypervisor</tag>
<tag name="operating-system">VMware ESXi</tag>
<tag name="mac-address">00:00:00:00:00:00</tag>
<tag name="traceroute-hop-0">172.28.28.29</tag>
<tag name="host-ip">172.28.28.29</tag>
<tag name="host-fqdn">foobar.com</tag>
<tag name="HOST_START">Thu Feb 20 12:30:14 2014</tag>
</HostProperties>`

type HostProperties struct {
    XMLName xml.Name `xml:"HostProperties"`
    Tags    []Tag    `xml:"tag"`
}

type Tag struct {
    Key   string `xml:"name,attr"`
    Value string `xml:",chardata"`
}

func main() {
    v := new(HostProperties)
    err := xml.Unmarshal([]byte(data), v)
    if err != nil {
        fmt.Printf("error: %v", err)
        return
    }
    fmt.Printf("v = %#v\n", v)

}

If you really want that `InfoList` structure you'll have to run through the `Tags` and fill it in. I'd probably just stick it in a `map[string]string` though like this

tags := make(map[string]string)
for _, tag := range v.Tags {
    tags[tag.Key] = tag.Value
}
fmt.Printf("map = %#v\n", tags)

Problem

I can't seem to figure out why this isn't working ``` type HostProperties struct { XMLName xml.Name `xml:HostProperties"` Info []InfoList `xml:"tag"` } type InfoList struct { HostEnd string `xml:",chardata"` PatchSummary string `xml:",chardata"` CPE1 string `xml:",chardata"` CPE0 string `xml:",chardata"` SystemType string `xml:",chardata"` OperatingSystem string `xml:",chardata"` MacAddress string `xml:",chardata"` Traceroute string `xml:",chardata"` IP string `xml:",chardata"` FQDN string `xml:",chardata"` HostStart string `xml:",chardata"` } <HostProperties> <tag name="HOST_END">Thu Feb 20 12:38:24 2014</tag> <tag name="patch-summary-total-cves">4</tag> <tag name="cpe-1">cpe:/a:openbsd:openssh:5.6 -&gt; OpenBSD OpenSSH 5.6</tag> <tag name="cpe-0">cpe:/o:vmware:esx_server</tag> <tag name="system-type">hypervisor</tag> <tag name="operating-system">VMware ESXi</tag> <tag name="mac-address">00:00:00:00:00:00</tag> <tag name="traceroute-hop-0">172.28.28.29</tag> <tag name="host-ip">172.28.28.29</tag> <tag name="host-fqdn">foobar.com</tag> <tag name="HOST_START">Thu Feb 20 12:30:14 2014</tag> </HostProperties> ``` Results ``` {HostEnd:172.28.28.29 PatchSummary: CPE1: CPE0: SystemType: OperatingSystem: MacAddress: Traceroute: IP: FQDN: HostStart:} ``` It creates a bunch of new slices with only the first element filled in and even then it's the wrong element. It's not filling out the other variables. The rest of the file seems to parse fine, just can't figure out this part.
