Remove binary data from html file using Java Regex

Question

I have html file that have tags for binary data like:

<HTML>
  <BODY STYLE="font: 10pt Times New Roman, Times, Serif">
    <TEXT>
      begin 644 image_002.jpg
        M_]C_X  02D9)1@ ! 0   0 !  #_VP!#  @&!@<&!0@'!P<)"0@*#!0-# L+
        M#!D2$P\4'1H?'AT:'!P@)"XG("(L(QP<*#<I+# Q-#0T'R<Y/3@R/"XS-#+_
        MVP!# 0D)"0P+#!@-#1@R(1PA,C(R,C(R,C(R,C(R,C(R,C(R,C(R,C(R,C(R
       ,Z4]1]: %HHHIB/_9
    end
   </TEXT>
   <TEXT>losses occurring in the third quarter and from weather  </TEXT>
  </BODY>
</HTML>

so I am trying to remove all "TEXT" tags those have binary data using Java Regex. I tried Jsoup library But it only remove html tags. I saw the same question here. But it is not using Java Regex.

Is any standard way to remove this binary data from html file?

It is well know that you shouldn't use a regex to handle xhtml.

I would use jsoup to remove the whole tag and later add it empty.

But if you want to use a regex, then you can use a regex like this:

"your html here".replaceAll("(?s)<TEXT>.*?<\\/TEXT>", "<TEXT></TEXT>")
