I am trying to replace html tags with updated values. I had tried using JSOUP but could not work out a way yet.
The functionality:
if (webText.contains("a href")) {
// Parse it into jsoup
Document doc = Jsoup.parse(webText);
// Create an array to tackle every type individually as wrap can
// affect whole body types otherwises.
Element[] array = new Element[doc.select("a").size()];
for (int i = 0; i < doc.select("a").size(); i++) {
if (doc.select("a").get(i) != null) {
array[i] = doc.select("a").get(i);
}
}
for (int i = 0; i < array.length; i++) {
if (array[i].toString().contains("http")) {
Log.e("Link", array[i].toString());
Pattern p = Pattern.compile("href=\"(.*?)\"");
Matcher m = p.matcher(array[i].toString());
String url = null;
if (m.find()) {
url = m.group(1); // this variable should contain the link URL
Log.e("Link Value", url);
array[i] = array[i].wrap("<a href='"+url+"' class='link'></a>");
}
}
else {
Log.e("Favourite", array[i].toString());
Pattern p = Pattern.compile("href=\"(.*?)\"");
Matcher m = p.matcher(array[i].toString());
String url = null;
if (m.find()) {
url = m.group(1); // this variable should contain the link URL
Log.e("Favourite Value", url);
array[i] = array[i].wrap("<a href='"+url+"' class='favourite'></a>");
//array[i] = array[i].replaceWithreplaceWith("","");
}
}
}
Element element = doc.body();
Log.e("From element html *************** ", " " + element.html());
String currentHtml = wrapImgWithCenter(element.html());
Log.e("currentHtml", currentHtml);
listOfElements = currentHtml;
}
This array[i] = array[i].wrap("<a href='"+url+"' class='favourite'></a>"); is basically wrapping the existing tags with the new value. But I do not want that to happen. I want to replace the tags completely with something like:
"<a href='"+url+"' class='favourite'>+url+"</a>";
Input:
<html>
<head></head>
<body>
<p dir="ltr"><a href="gYWMBi5XqN" class="favourite"></a><a href="gYWMBi5XqN"><font color="#009a49">Frank Frank</font></a> <a href="http://yahoo.co.in" class="link"></a><a href="http://yahoo.co.in"><font color="#0033cc">http://yahoo.co.in</font></a></p>
<br />
<br />
</body>
</html>
Expected output:
<html>
<head></head>
<body>
<p dir="ltr"><a href="gYWMBi5XqN" class="favourite"><font color="#009a49">Frank Frank</font></a> <a href="http://yahoo.co.in" class="link"><font color="#0033cc">http://yahoo.co.in</font></a></p>
<br />
<br />
</body>
</html>
I have tried using replaceWith but was unsuccessful. You can still find it commented out in the source code provided above. Please tell me where am I going wrong? What should I do to update the tags?
P.S.: The input might be variable with some more or less tags.
