Left angle bracket in file name => MalformedXML

[rips-hb]

Hi there,

when I am trying to delete something with

$s3->deleteMatchingObjects(AWS_S3_BUCKET, (int)$id . '/');

and there is a file in there with a < in the name I get the following error:

Aws\S3\Exception\S3Exception: Error executing "DeleteObjects" on "https://s3.xxx.amazonaws.com/xxx?delete"; AWS HTTP error: Client error: `POST https://s3.xxx.amazonaws.com/xxx?delete` resulted in a `400 Bad Request` response: <?xml version="1.0" encoding="UTF-8"?> <Error><Code>MalformedXML</Code><Message>The XML you provided was not well-formed (truncated...)

I am running version 3.18.16, but it also did not work in older versions. Any idea what could cause this or better: how to fix this?

Thanks!

@rips-hb, Since xml that doesn't conform to the published xsd schema and fails the validation, I'd suggest some work around. This is caused by improperly encoded path, since the file name contains special characters, could you try '/' . rawurlencode(SPECIAL_FILE_KEY) for those files?

[rips-hb]

Thanks for the answer. I already do replace the character when writing the files as a workaround, it just feels a bit hackish to me. If I forget to do it somewhere in the future I will end up with a undeletable directory.

@rips-hb ,Since an XML parsing exception due to unescaped XML characters in the XML response is a server side issue that cannot be fixed by the SDK, so it would be great if you could let the Amazon S3 team know that this is important to you by posting to their forum. Great thanks for your feedback!

I'll going to close this issue, yet feel free to reopen if you have further questions :)
