Notepad++ 正则表达式查找不包含某些子 XML 标签的 XML 标签

Question

I am trying to look in notepad++ for XML tags which does not contain a certain child tag. For example you have a lot of XML tags like this:

<situation xsi:type="management" id="...">
        ....
        <mobility>
            ...
        </mobility>
        .....
</situation>

And some of them do not contain the mobility tag like this:

<situation xsi:type="management" id="...">
        ....
</situation>

For the one with the mobility tag I know that you can search it up when you create a regex like this:

<situation xsi:type="management"(?:(?!</situation>).)+<mobility>([^\"]*)</mobility>

What changes do need to be made with the regex above to search for situations without the mobility child tag?

Answer 1

Make the <mobility> tag optional:

<situation xsi:type="management"(?:(?!</situation>).)+(?:<mobility>([^\"]*?)</mobility>)?

---

If you want to match <situation> tag that doesn't contain <mobility> tag, use:

<situation xsi:type="management"(?:(?!</situation>)(?!<mobility>).)+</situation>
