Change href value in android to local one using JSoup
0
How can I change the value of href in HTML code of some page stored locally in Android?
private void changeHrefsToLocal(String pageName) throws IOException {
File input = new File(appContext.getFilesDir(), pageName);
Document savedDoc = Jsoup.parse(input, "UTF-8");
Elements links = savedDoc.select("a[href]");
String href;
for(Element link : links){
href = appContext.getFilesDir() + "/" + link.attr("abs:href").replace(INDEX_URL, "") + ".html";
link.attr("href", href);
}
}
Logs:

If I print the link to the logs before and after the method runs, there's the expected change, although there's no change in the local .html file, which is the main problem.

Welcome. How are you printing those logs? Your code doesn't include the part that you actually save your changes back to the file. Maybe you miss that?

Thanks Bruno, that's a really good point. I indeed missed writing those changes to the file. As I understand, the link.attr(...) doesn't impact the file I'm working on, since it is a different document/set of links copied from the document? If that's so, how can I commit those changes to the local file?

My pleasure :) Maybe you should check the docs for JSoup on how to save a Document back to a file? I know nothing about JSoup, sorry

Its simple just save the edited html file back.
Here is the sample code
File input = new File(appContext.getFilesDir(), pageName);
Document savedDoc = null;
try {
savedDoc = Jsoup.parse(input, "UTF-8");
} catch (Exception e) {
Log.e("Error ", e.toString());
}
Elements links = savedDoc.select("a[href]");
for(Element link : links){
link.attr("href", "changed value");//change the value of href attribute here
}
//save the updated/edited html file
PrintWriter writer;
try {
writer = new PrintWriter(input,"UTF-8");
writer.write(savedDoc.html() ) ;
writer.flush();
writer.close();
} catch (Exception e) {
Log.e("Error ", e.toString());
}
