How can i read line break from xml?

[zk-kiger]

i want read '\r\n\n' from xml content by Poco::XML, but i can't read '/r' when i print log.

code:

const auto& content = req->GetContent();
XMLDocumentPtr doc = dom_parser.parseString(content);
...
auto* record_delimiter = csv->getNodeByPath("RecordDelimiter");
auto delimiter = record_delimiter->innerText();
LOG_DEBUG(log, "csv input record delimiter: {}, length: {}", delimiter, delimiter.length());

result log:

csv input record delimiter:

,  length: 2

input xml:

<CSV>
    <RecordDelimiter>/r/n/n</RecordDelimiter>
</CSV>

what should i do can reserve '/r'
