replaceAll Use

[vunet.us]

How can I use replaceAll function to remove XML declaration line:
<?xml version="1.0" encoding="US-ASCII"?>

This did not work:

String newXML = myXML.replaceAll("<?xml version=\"1.0\"
encoding=\"US-ASCII\"?>","")
It has something to do with regular expressions.... I guess.

PS: Yes, I do need to remove that XML declaration.

You should use \? instead of ? in the regular expression

You should use \? instead of ? in the regular expression

Or use literal pattern:

Pattern p = Pattern.compiler(xmlDeclarationLine, Pattern.LITERAL);
p.matcher(xmlString).replaceAll("");

\? shows error invalid escape character

\? shows error invalid escape character

You need to escape the \ for the Java compiler, so that your string
contains \?
"\\?"

However. Why are you using replace all for something that is only
supposed occure on the first line?
Why not:

if (myXml.startsWith("<?xml")) {
myXml.substring(myXml.indexOf("\n") + 1);
}

I think so too.

If you are on Java 1.5 or newer then use:

String newXML = myXML.replace("<?xml version=\"1.0\"
encoding=\"US-ASCII\"?>","")

It does not use regex.
