I want to take an XML file as input which contains the following:
<?xml version='1.0' encoding='utf-8' standalone='yes'>
<map>
<int name="count" value="10" />
</map>
and, read and change the value from 10 to any other integer value.
How can I do this in Android/Java. I'm new to Android and Java and all the tutorials available on the internet are way too complicated.
Thank You
You can change the value by matching the pattern and replacing the string as like below,
String xmlString = "<int name=\"count\" value=\"10\" />";
int newValue = 100;
Pattern pattern = Pattern.compile("(<int name=\"count\" value=\")([0-9]{0,})(\" />)");
Matcher matcher = pattern.matcher(xmlString);
while (matcher.find()) {
String match = matcher.group(2);
xmlString = xmlString.replace(match, String.valueOf(newValue));
}
System.out.println(xmlString);
You can find your answer here. It is like parsing json. You can cast your string(from file) to object and do anything with parameters
