XQuery Marklogic 中 XML 到 json 转换期间的附加反斜杠

Question

I'm working with XML to JSON conversion in XQuery for the content with special characters.

XML: <text>$$\parent* \$$</text>

Using json:transform-to-json() with custom config, getting the below result

Actual result: { "text": "$$\\parent* \\$$" }

Expected result: {"text": "$$\parent* \$$"}

I tried multiple ways like using xdmp:quote() and xdmp:to-json() methods but not giving the expected result.

Is there a way to restrict the addition of extra backslash during conversion in XQuery?

Answer 1

{"text": "$$\parent* \$$"} is not valid JSON.

In JSON the \ needs to be escaped as \\ .

You can verify that what is currently being produced is valid, and what you are expecting to be validated is invalid by validating them on https://jsonlint.com

Don't confuse what you see in the JSON value with the data that it represents. The value $$\parent* \$$ in JSON is $$\\parent* \\$$ , but when you parse/read and ask for the value of text using APIs, it will return $$\parent* \$$ .
