Java Splitting string including patterns into an Array

Question

I'm trying to pseudo translate the text embedded within HTML in a string. I don't want to touch the actual html tags or its attributed, just the content.

So for example, if I have something like:

<td colspan='2'><a>This is a Text in <b>Bold</b></a></td>

I want this to be eventually modified into

<td colspan='2'><a>Thìs ís à Tèxt îñ <b>Bòlð</b></a></td>

1) I can't use any third party libraries, so I'm using standard regex to parse html 2) I tried both pattern.match() and pattern.split() but both seem to have a few limitations. pattern.split() helps with splitting the string based on a regex pattern, but I lose the actual pattern in that process. Pattern.match helps with retaining the pattern, but I can't guarentee the markup.

So ideally I would want something to take the string with HTML and break it into an array like

array[0]: HTML Tag
array[1]: Plain Text
array[2]: HTML Tag
array[3]: Plain Text
array[4]: HTML Tag
array[5]: Plain Text
array[6]: HTML Tag

Any ideas ?

I'd look into an HTML parsing lib like Jsoup to do what you want — Ryan J

Forcing you to use regex for parsing any html/xml style language is lunacy. The first rule of regex re:html is don't parse html with regex. stackoverflow.com/questions/590747/… — KevinDTimm

As regex, you could use this one:

(?<=>)[^>]+(?=<)

I'm assuming here that you have a replace function that can take a captured group and mingle its text:

String str = "<td colspan='2'><a>This is a Text in <b>Bold</b></a></td>";
str.replaceAll("(?<=>)[^>]+(?=<)","");

However, without knowing how you intend to "pseudotranslate" a string, we can't really help you further. For custom replacement methods, this answer may be useful.
