Re: What is the best way to cast integer to string in
Hi Mike and Jeni,
Here is my interpretation.
The position() functions returns an xsd:integer, as the error message indicates. The concat() function takes only xsd:string arguments. Since the first argument you are supplying to concat() is not an xsd:string a type mismatch occurs and you get the error message that you report.
Why wasn't it automatically cast to xsd:string? Automatic casting in XSLT 2.0 / XPath 2.0, as I understand it, will only take place when the data is untyped. For example, if you supplied as an argument to concat() untyped data such as the content of <someElement>Blah blah</someElement> the content would be treated internally as xdt:anyAtomicType. The XSLT processor *would* automatically cast xdt:anyAtomicType to xsd:string if you supply that to concat() as an argument, but won't (without explicitly being told) cast an xsd:integer to an xsd:string.
2. My current solution is to use
It's what I would do.
I hope that helps.
