DevOps, CI/CD and Automation

Hi All

I am recieving XML's in which i have a few elements that have base64 strings as data.

e.g

<CompletionDetails>
<SignedBy>MR XXXXXXXXXX</SignedBy>
<EngineerSignature type="rle4">AQ==</EngineerSignature>
<CustomerSignature type="rle4">AA==</CustomerSignature >
<Comments />
<WorkCarriedOut />
<Reports>
<Report name="JobReport" type="pdf">AA==</Reports>
</CompletionDetails>

i have been looking for days on simple steps on how to convert this base64 string to images that are written as .jpegs or .bnp and eventually pdfs to a directory (locally to my machine for now) and store the dir/file name within a table.

can anyone give me a simple step ny step process on how to do this...

i am using 10g and do not have a registered is there a solution without registering a schema????

Thanks in advance!
