How to retrieve value of an attribute which contains colon in the attribute name using xpath

I have a simple requirement where in I need to fetch the value of attribute xml:id i.e af1. I am making use of a SAXParser and here is my xpath:a/aff/@xml:id on the contrary I was able to fetch value of using the xpath:a/aff/@value.

But i was unable to retrieve the value could you please help me?

<?xml version="1.0" encoding="UTF-8" ?>
<a>
   <aff xml:id="af1" value="a">
        <uAff>
            Hello
        </uAff>
    </aff>
    <aff xml:id="corr1">
        <uAff>
            Hello1
        </uAff>
    </aff>
</a>

Thanks in advance.

@tibtof's solution worked for my complex Cordova config.xml transformation using gulp and gulp-xml-transformer to fix the ionic-plugin-deeplinks AndroidManifest.xml implementation by targeting the android:host attribute like so since the colon in the attribute name would not work with path: '//xmlns:platform[@name="android"]/xmlns:config-file/xmlns:intent-filter/xmlns:data[@android:host]':

gulpfile.js:

var gulp = require('gulp'),
    xeditor = require("gulp-xml-transformer");

function config(avc, bundleId, ioscfbv, version, appLabel, hostname, done) {
  gulp.src('config.xml')
    .pipe(xeditor([
        {
            path: '//xmlns:widget',
            attr: { 'android-versionCode': avc, 'id': bundleId, 'ios-CFBundleVersion': ioscfbv, 'version': version }
        },
        {
            path: '//xmlns:name',
            text: appLabel
        },
        {
            path: '//*[@name="Hostname"]',
            attr: { 'value': bundleId }
        },
        {
            path: '//*[@name="ios"]/xmlns:config-file/xmlns:array/xmlns:string',
            text: 'applinks:' + hostname
        },
        {
            path: '//xmlns:platform[@name="android"]/xmlns:config-file/xmlns:intent-filter/xmlns:data[@*[name()="android:host"]]',
            attr: { 'android:host': hostname }
        }
    ], 'http://www.w3.org/ns/widgets'))
    .pipe(gulp.dest('.'))
    .on('finish', done);
}

config.xml:

<widget xmlns="http://www.w3.org/ns/widgets" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:cdv="http://cordova.apache.org/ns/1.0" android-versionCode="0" id="com.bundle.placeholder" ios-CFBundleVersion="1.0.0.0" version="1.0.0">
    ...
    <platform name="android">
        ...
        <config-file target="AndroidManifest.xml" parent="/manifest/application/activity">
            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW"/>
                <category android:name="android.intent.category.DEFAULT"/>
                <category android:name="android.intent.category.BROWSABLE"/>
                <data android:scheme="https"/>
                <data android:host="com.bundle.placeholder"/>
            </intent-filter>
        </config-file>
        ...
    </platform>
    ...
</widget>

To get the value of the attributes you could use:

/a/aff/@*[name()='xml:id']

/a/aff/@xml:id works just fine in getting the values...

Are you trying to get both values?

If you are trying to get just the first value you could use /a/aff[1]/@xml:id
