The XPath concat() functions accepts as many arguments as required so you can have"concat($a,’b’,$c)" rather than "concat($a,concat(‘b’,$c)".
This rule is defined by the following XPath expression:
//node()[contains(substring-after(@select,'concat'),'concat')]Example(s):
<xsl:variable name="var" select="concat("Welcome",concat("to you ",$name))"/><xsl:variable name="var" select="concat("Welcome","to you ",$name))">Use this rule by referencing it:
<ruleref="category/xsl/codestyle.xml/UseConcatOnce"/>
