Parsing a file containing a list of xmls and modifying the same

Question

I have a file which contains a list of xmls , one on each line. When I try to parse this file using the code given here:

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(filepath);

I get parsing error when my file looks like this(multiple xmls, say File1)-

<T1>  
    <T2>    
        <T4>        
            <T3>TEST</T3>   
        </T4>  
    </T2>   
    <T5>    
        <TID>NEwid:0</TID>  
    </T5> 
</T1>
<T1>  
    <T2>    
        <T4>        
            <T3>TEST</T3>   
        </T4>  
    </T2>   
    <T5>    
        <TID>NEwid:1</TID>  
    </T5> 
</T1>

However, following file parses successfully(single xml, say File2)

<T1>  
    <T2>    
        <T4>        
            <T3>TEST</T3>   
        </T4>  
    </T2>   
    <T5>    
        <TID>NEwid:0</TID>  
    </T5> 
</T1>

My requirement is that I need to replace the value of tag in each of the xmls which will be present in a single file(the file format will be like File1 ).Am not sure if File1 is even a proper xml , but that is how the file is like. I am able to replace the value of when I place only one xml in a file . (Have used the best answer stated here: How to update xml files in java)

A file that "contains a list of xmls [sic]" is not XML; an XML document must have a single root element. — kjhughes, Jun 27 '17 at 20:14
@kjhughes So reading the file , using regex and replacing the tag value, writing back to file is my only option then? — Manas Saxena, Jun 27 '17 at 20:16

Is there any way a single file to contain multiple xml using some xml end character or something? — Manas Saxena, Jun 27 '17 at 20:20
An XML document must have a single root element; asking again won't change the answer. — kjhughes, Jun 27 '17 at 20:25
