Server Side Java Automatic Css Inliner

December 27, 2010 Leave a comment Go to comments

Esta clase sirve, como dice el titulo, para pasar los estilos de una pagina html a sus atributos, utilizando la librería JSoup.


body{background:#FFC} p{background:red} 
body, p{font-weight:bold} 


<body style=”background:#FFC;font-weight:bold”>
<p style=”background:red;font-weight:bold”>…</p>


//---------Empieza Clasee
import java.io.IOException;
import java.util.StringTokenizer;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public class AutomaticCssInliner {

    public static void main(String[] args) throws IOException {
        final String style = "style";
        Document doc = Jsoup.connect("http://mypage.com/inlineme.php").get();
        //Document doc = Jsoup.parse(html);
        Elements els = doc.select(style);// to get all the style elements
        for (Element e : els) {
            String styleRules = e.getAllElements().get(0).data().replaceAll(
                "\n", "").trim(), delims = "{}";
            StringTokenizer st = new StringTokenizer(styleRules, delims);
            while (st.countTokens() > 1) {
                String selector = st.nextToken(), properties = st.nextToken();
                Elements selectedElements = doc.select(selector);
                for (Element selElem : selectedElements) {
                    String oldProperties = selElem.attr(style);
                    oldProperties.length() > 0 ? concatenateProperties(
                    oldProperties, properties) : properties);
        System.out.println(doc);// now we have the result html without the
        // styles tags, and the inline css in each
        // element

    private static String concatenateProperties(String oldProp, String newProp) {
        oldProp = oldProp.trim();
        if (!oldProp.endsWith(";"))
            oldProp += ";";
        return oldProp + newProp;
