Remove space between the beginning and the end of xml tag

I need a regex to remove the spaces between the beginning and the end of xml tags. For example: Someone create the xml and send it to me, so i can validate, sign and send to a webservice.

To do this i need to remove the spaces between the beginning and the end of the tags: String xmlString = "<?xml version="1.0" encoding="UTF-8"?><car><name>Beatle </name>" + "<doors>2</doors><drivers><driver><name> Guilherme</name></driver>" + "<driver><name>Leonardo </name></driver></drivers></car>";
xmlString = xmlString.replaceAll("> ", ">"); xmlString = xmlString.replaceAll(" <", "<");

Is there a way to turn this two replaces into one with regex?

(>) | (<)

You can use | or operator and replace by $1$2.Done in 1 regex.

You can use this regex:

(<[^/][^>]*>) +| +(<\/[^>]+>)

(In Java, this should be used like String pattern = "(<[^/][^>]*>) +| +(<\\/[^>]+>)";)

And apply the following replacement string:

$1$2

Check Replace, Global.

Tested against:

<?xml version="1.0" encoding="UTF-8"?><car><name>Beatle </name> <doors>2</doors><drivers><driver><name> Guilherme</name></driver> <driver><name>Leonardo </name></driver></drivers></car>

Output:

<?xml version="1.0" encoding="UTF-8"?><car><name>Beatle</name> <doors>2</doors><drivers><driver><name>Guilherme</name></driver> <driver><name>Leonardo</name></driver></drivers></car>
