Java String Replace Xml tag which has some specific word

Question

I need to remove XML tag in a string which ends with "section". For example in the below XML string

<OldSection>
    <sectionTitle>Sample Title</sectionTitle>
    <label> Hello Label </label>
    <heading>Hi </heading>
    <NewSection>
        <section>
            <InteractionSection>
                <sectionTitle>Section Title</sectionTitle>
                <label> Hello </label>
                <heading>Hi </heading>
                <para>
                    ...
                    ...
                </para>
            </InteractionSection>
        <section>
    </NewSection>
</OldSection>

I want to remove tags which ends with section i.e <OldSection>, </OldSection> ,<NewSection></NewSection>, <InteractionSection>, </InteractionSection> etc. The tag alone should be removed and not the contents with in the tag.

I tried the following code but not working..

stringformat sf = new stringformat();

// REturns the xml string given as input 
String s = sf.getString(); 
String f = s; 

f = f.replaceAll("\\<*Section[^>].*?\\>", "");

Please any suggestions.

Use SAX. Don't try to use regular expressions to crunch XML. — Dawood ibn Kareem

In question like this you should inculde what exactly is not working. Otherwise people have to guess what your problem is. — Viktor Seifert

Don't try to play with Strings using regex. I would suggest that you do marshalling and unmarshalling. Unmarshall your XML into a class. Copy your requisite class contents into another class using Apache Commons' BeanUtils and then marshall this back into XML.
