Java Regex check if string contains XML tag -

i trying determine if string contains @ least 1 xml tag using string.match() function. due way project set up, prefer if didn't have use pattern.

currently use regex:

<[a-za-z0-9]+>

which checks if string has right , left arrow brackets contains text. need way check if string has single xml tag regex, eg input like:

blah <abc foo="bar">blah</abc> blah blah <abc foo="bar"/>

but not input like:

blah <abc> blah blah <abc </abc> blah

is possible?

this:

if (input.matches("(?s).*(<(\\w+)[^>]*>.*</\\2>|<(\\w+)[^>]*/>).*"))

matches both types of tag (standard , self-closing):

<abc foo="bar">blah</abc> <abc foo="bar"/>

without matching incomplete tags like:

<abc>
