逐行读取XML文件

I am new to go and trying to write a script to parse multiple soap responses.

Here is a snippet of the xml snippet of the xml I am trying to parse. Its a full SOAP response but I have just included that tags I wish to parse

            <Results xsi:type="AccountUser">
                <Client>
                    <ID>72rere341</ID>
                </Client>
                <PartnerKey xsi:nil="true" />
                <PartnerProperties>
                    <Name>email</Name>
                    <Value>example1@test1.com</Value>
                </PartnerProperties>
                <ID>755454475</ID>
                <ObjectID xsi:nil="true" />
                <UserID>5fd0acfc-6crerfrgrfe6e9a675f65</UserID>
                <ActiveFlag>true</ActiveFlag>
                <Delete>0</Delete>
                <LastSuccessfulLogin>2014-11-07T16:00:46.747</LastSuccessfulLogin>
            </Results>
            <Results xsi:type="AccountUser">
                <Client>
                    <ID>72rere5341</ID>
                </Client>
                <PartnerKey xsi:nil="true" />
                <PartnerProperties>
                    <Name>email</Name>
                    <Value>example2@test1.com</Value>
                </PartnerProperties>
                <ID>7225483</ID>
                <ObjectID xsi:nil="true" />
                <UserID>example2@test1.com</UserID>
                <ActiveFlag>false</ActiveFlag>
                <Delete>0</Delete>
                <LastSuccessfulLogin>2015-04-29T05:01:27.85</LastSuccessfulLogin>
            </Results>

I would like to print each result on a new line.

Here is a snippet of my code:

package main 


import (

    "os"
    "fmt"
    "encoding/xml"
    "io/ioutil"

)

type AccountUser struct {


    ParentMID string `xml:"Client>ID"`
    EmailAddress string `xml:"PartnerProperties>Value"`
    BuinessUnit string `xml:"ID"`
    UserID string `xml:"UserID"`
    Active string`xml:"ActiveFlag"`
    LastSucessfulLogin string`xml:"LastSucessfulLogin"`

}

type Email struct {

    Email string `xml:"PartnerProperties>Value"`
}


type Query struct {
    Accounts AccountUser
    AccountList []Email `xml:"PartnerProperties>Value"`
}

func (a AccountUser) String() string {
    return fmt.Sprintf("%s - %s - %s", a.ParentMID, a.EmailAddress, a.UserID)
}


func main() {
    xmlFile, err := os.Open("Results.xml")
    if err != nil {
        fmt.Println("Error opening file:", err)
        return
    }
    defer xmlFile.Close()

    b, _ := ioutil.ReadAll(xmlFile)

    var q Query
    xml.Unmarshal(b, &q)

    fmt.Println(q.Accounts)
    for _, account := range q.AccountList {
        fmt.Printf("\t%s
", account)
    }
}

When I run this in terminal, It returns nothing ie.

-     - //just the string in the function

I would love pointers on how I can resolve this.

There are some problems with your code :

First is your xml file is not correct the correct xml file must contains parent xml like <Data> //Yourdata here </Data> it must be look like this :

<?xml version="1.0" encoding="UTF-8" ?>
<Data>
    <Results>
        <Client>
            <ID>72rere341</ID>
        </Client>
        <PartnerKey xsi:nil="true" />
        <PartnerProperties>
            <Name>email</Name>
            <Value>example1@test1.com</Value>
        </PartnerProperties>
        <ID>755454475</ID>
        <ObjectID xsi:nil="true" />
        <UserID>5fd0acfc-6crerfrgrfe6e9a675f65</UserID>
        <ActiveFlag>true</ActiveFlag>
        <Delete>0</Delete>
        <LastSuccessfulLogin>2014-11-07T16:00:46.747</LastSuccessfulLogin>
    </Results>
    <Results>
        <Client>
            <ID>72rere5341</ID>
        </Client>
        <PartnerKey xsi:nil="true" />
        <PartnerProperties>
            <Name>email</Name>
            <Value>example2@test1.com</Value>
        </PartnerProperties>
        <ID>7225483</ID>
        <ObjectID xsi:nil="true" />
        <UserID>example2@test1.com</UserID>
        <ActiveFlag>false</ActiveFlag>
        <Delete>0</Delete>
        <LastSuccessfulLogin>2015-04-29T05:01:27.85</LastSuccessfulLogin>
    </Results>
</Data>

Second your struct AccountUser has a method:

func (a AccountUser) String() string {
    return fmt.Sprintf("%s - %s - %s", a.ParentMID, a.EmailAddress, a.UserID)
}

To fix your problem fix the your xml file, and make your String() method like this :

func (a *AccountUser) String() string {
    return ""
}

And here is the working code that I have tried with the above xml file :

package main

import (
    "encoding/xml"
    "fmt"
    "io/ioutil"
    "log"
    "os"
)

type AccountUser struct {
    UserID              string
    ActiveFlag          string
    LastSuccessfulLogin string
    PartnerProperties   Partner `xml:"PartnerProperties"`
}

type Partner struct {
    Name  string
    Value string
}

type Query struct {
    ResultList []AccountUser `xml:"Results"`
}

func (a *AccountUser) String() string {
    return fmt.Sprintf("%s - %s - %s", a.PartnerProperties.Name, a.PartnerProperties.Value, a.UserID)
}

func main() {
    xmlFile, err := os.Open("read.xml")
    if err != nil {
        fmt.Println("Error opening file:", err)
        return
    }
    defer xmlFile.Close()

    b, err := ioutil.ReadAll(xmlFile)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println("read result = ", string(b))

    var q Query
    err = xml.Unmarshal(b, &q)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(q.ResultList[0].String())
}

From my limited knowledge your assignment needs to be a pointer so try Accounts *AccountUser instead of Accounts AccountUser

You might want to supply the XML so it is easier for others to understand and show examples with.
