查找XML标签值的正确正则表达式-Java

Question

I would like to find correct regex to get value of xml tag and replace it with X . This tag:

<number>1234I0000ABC0001</number>

I creted regex like this:

.*number>([A-Z0-9 _]*[A-Z0-9][A-Z0-9 _]*)</

but it is not work as weel as I want. I would like to get the value by regex, replace all characters with X and set this changed value into tag.

Answer 1

It s not a good idea to parse XML with regex. But if you insist then you can use

<number>([\\s\\S]*?)<\\/number>

this will capture the value as Group 1 . You can easily replace that with whatever you like. For detail explanation you can visit this regex101 in live action

Answer 2

You might look at something like this :

(<.+>)(.+)(</.+>)

or

<number>(.+?)</number>

I have to note that it is not actually a number :-)

It'll be group(1)
