Specific attribute with Xmlpullparser

Question

Good afternoon, everyone,

I’m trying to consume an XML file from a Url. So far so good.

Only I am consuming by the tag "img" and the attribute "src". Only the tag "img" appears twice and each one has its "src".

the "src" of the first tag that interests me.

How do I set this specific attribute?

Follow example of XML and later code.

Solution

try {
        factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(true);
        XmlPullParser xpp = factory.newPullParser();

        URL url = new URL(XMLFile);
        URLConnection conn = url.openConnection();
        InputStream input = conn.getInputStream();

        xpp.setInput(input, null);

        int eventType = xpp.getEventType();

        while (eventType != XmlPullParser.END_DOCUMENT) {
            if (eventType == XmlPullParser.START_TAG && xpp.getName().equalsIgnoreCase("img")
                    && Integer.parseInt(xpp.getAttributeValue(null, "width")) == 450
                    && Integer.parseInt(xpp.getAttributeValue(null, "height")) == 517){

                    image = new ImageModel();
                    image.setUrl(xpp.getAttributeValue(null, "src"));
                    data.add(image);
            }
            eventType = xpp.next();
        }
    } catch (XmlPullParserException | IOException e) {
        e.printStackTrace();
    }
