Question

我如何能够提取与＃34; main.mp3＆＃34;相关的源IP？从下面的xml源

安装点

我当前的代码获取列表中的第一个恰好是listen.mp3挂载点，但是我希望将提取绑定到特定的挂载点

提取源IP的代码：

SERVER = 'http://localhost:8382/admin/stats.xml'
authinfo = urllib2.HTTPPasswordMgrWithDefaultRealm()
authinfo.add_password(None, SERVER, 'xxxxxx', 'xxxxxxx')
page = 'http://localhost:8382/admin/stats.xml'
handler = urllib2.HTTPBasicAuthHandler(authinfo)
myopener = urllib2.build_opener(handler)
opened = urllib2.install_opener(myopener)
output = urllib2.urlopen(page)
soup = BeautifulSoup(output.read(), "lxml")
print "source ip: ",soup.select('source_ip')[0].text

我已将您的XML数据粘贴到excercise.xml文件中，它应该可以正常使用python 3.x

void checkConnection(ActionEvent event) throws IOException {
    final String adress = uiURL.getText();
    if (adress == null || adress.isEmpty()) {
        Rhomeo.showAlert(Alert.AlertType.WARNING, "Impossible");
    }
    // Adapt
    Properties prop = new Properties();
    FileInputStream input = null;
    input = new FileInputStream("src/main/resources/Pass2.properties");
    prop.load(input);
    final String pw2 = prop.getProperty("password");
    // End Adapt

    final int port = uiPort.getValue();
    final String workDir = uiDir.getText();
    final String login = uiLogin.getText();

    final TaskManager.MockTask t = new TaskManager.MockTask(() -> FTPAccess.createClient(adress, port, workDir, login, pw2));

    t.setOnSucceeded(
        (evt) -> Platform.runLater(() -> {
            if (t.getValue() != null) {
                Rhomeo.showAlert(Alert.AlertType.INFORMATION, "Connexion établie");
            } else {
                Rhomeo.showAlert(Alert.AlertType.WARNING, "Aucune réponse du serveur !");
            }
        })
    );


    t.setOnFailed(evt -> Platform.runLater(() -> GeotkFX.newExceptionDialog("Impossible de se connecter au service FTP", t.getException()).show()));

    t.runningProperty().addListener((obs, oldValue, newValue) -> uiTest.setDisable(newValue));
    TaskManager.INSTANCE.submit("Test de connexion", t);
}

Answer 2

使用ElementTree，附带Python。

import xml.etree.ElementTree as ET
tree = ET.fromstring(xml)

for s in tree.iter('source'):
    print(s.attrib) # dictionary with all attributes
    print(s.text) # there might also be text
    print(s.get('mount')) # this is the info you want
    print(s.attrib['mount']) # or like this

Answer 3

您可以选择容器＆＃39;来源＆＃39;标签并收集＆＃39; source_ip＆＃39;每个IP都标记，因此每个IP都与一个挂载点相关。

soup = BeautifulSoup(xml, "lxml")
for mount in soup.select('source[mount]'):
    print "mount point: ", mount['mount']
    print "source ip: ", mount.select_one('source_ip').text

或者您可以创建字典并通过挂载点选择IP，例如

data = {
    mount['mount']: mount.select_one('source_ip').text 
    for mount in soup.select('source[mount]')
}
print data['/listen.mp3']

如果您只想从特定点选择IP，只需选择＆＃39; source_ip＆＃39;该节点上的标记。

ip = soup.select_one('source[mount=/main.mp3] source_ip').text
print "source ip:", ip

从特定xml节点
