xquery - BaseX: correct syntax to place multiple 'replace ' -

declare function local:stripns($name xs:string?) xs:string? {   if(contains($name, ':'))   substring($name, functx:index-of-string($name, ':') + 1)   else $name };  $x in doc("test.xml")//*[@ref] let $tmp:=local:stripns($x/@ref) return replace value of node $x/@ref $tmp 

i want strip namespace value of ref , type attribute. <test ref='haha:123' type='hehe:456'/> should become <test ref='123' type='456'/>. don't know correct syntax, below ideal .xqy file want:

declare function local:stripns($name xs:string?) xs:string? {   if(contains($name, ':'))   substring($name, functx:index-of-string($name, ':') + 1)   else $name };  $x in doc('test.xml')//*[@ref] let $tmp:=local:stripns($x/@ref) return replace value of node $x/@ref $tmp,  $x in doc('test.xml')//*[@type] let $tmp:=local:stripns($x/@type) return replace value of node $x/@ref $tmp 

but contains syntax error:

[xudy0017] node can replaced once: attribute ref {"123"}.

$ basex -u test.xqy

use command above test. output written test.xml.

the issue you're having typo in second flwor expression: try replace same attribute twice.

for $x in doc('test.xml')//*[@type] let $tmp:=local:stripns($x/@type) return replace value of node $x/@ref $tmp                              (: ^^^^ should @type :) 

anyway, query overly complex. first of all, xquery knows substring-after($string, $token) function you're rewriting yourself. can cut down function to

declare function local:stripns($name xs:string?) xs:string? {   if(contains($name, ':'))   substring-after($name, ':')   else $name }; 

while @ same time removing functx dependency.

furthermore, can select multiple, different attributes single query, simplifying query to

for $attribute in doc('test.xml')//(@ref, @type) return replace value of node $attribute local:stripns($attribute) 

finally, adding simple where clause lets give whole function (and reducing number of updates attributes @ same time, speed query large documents):

for $attribute in doc('test.xml')//(@ref, @type) contains($attribute, ':') return replace value of node $attribute substring-after($attribute, ':')
