Is it HTML or XML? If you need to convert HTML, you can directly pass on binary data to html:parse. What does inspect:type(http:send-request(...)[2]) return? Best, Christian

Thanks. If your data is HTML, html:parse is the correct choice. fetch:binary-doc can be used to convert a binary item to a document node [1]:
let $b64 := xs:base64Binary(<data>PHgvPg==</data>)
return (
  fetch:binary-doc($b64),
  html:parse($b64)
)

Hello, I am calling a SOAP Web Service via http:send-request(...) method. It returns back base64 encoded XML. Here is how I am converting it into XML:
return
html:parse(convert:binary-to-string(xs:base64Binary(http:send-request(...)))
)
So, I am using three function/method calls: - xs:base64Binary() - convert:binary-to-string() - html:parse() Is there a more straight forward method to convert base64 encoded string to XML in the BaseX 10.0? Regards, Yitzhak Khabinsky

I need one particular base64 encoded XML element, i.e. <data> The following call: return inspect:type(http:send-request(...)//*:data) returns the following: element()

Mr. Grün, As suggested, I tried the following, and it worked: return fetch:binary-doc(xs:base64Binary(http:send-request(...)//*:data) It reduced three calls to two. IMHO, it is a good idea to add such functionality to the Conversion Module: convert:base64-to-XML https://docs.basex.org/wiki/Conversion_Module Much appreciated. Regards, Yitzhak Khabinsky
