[basex-talk] Context node required problem

Hi

I am trying to pass a string to my XQuery as a parameter, $input below. It seems that the string is not being interpreted as XML as I get the following message when I run the query from my .Net client:

Stopped at line 14, column 68:

[XPTY0019] Context node required for sglines; xs:string found.

I believe I don't have the syntax of "declare context item as element(sglines) := document {$input/sglines};" quite right, and maybe " for $i in //line"

The XML I am passing in as a parameter is:

<sglines>

<line lineId="41" note="1064"/>

<line lineId="3" note="0"/>

<line lineId="5" note="0"/>

<line lineId="7" note="0"/>

<line lineId="11" note="0"/>

<line lineId="12" note="0"/>

<line lineId="33" note="0"/>

<line lineId="80" note="0"/>

<line lineId="34" note="0"/>

<line lineId="50" note="0"/>

<line lineId="51" note="0"/>

<line lineId="52" note="0"/>

<line lineId="60" note="0"/>

<line lineId="61" note="0"/>

<line lineId="80" note="0"/>

</sglines>

Help would be much appreciated.

Thanks

Best regards
