Subject: RE: [xsl] conditional instruction vs. conditional expression From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Thu, 27 Jan 2005 18:11:57 -0000 |
In the first case, you aren't actually passing a string: you are passing a tree consisting of a document node and a text node as its child. This is a much more heavyweight structure than the string which you pass in the second case, because nodes have identity, base URI, parent pointers, etc. Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: Kevin Rodgers [mailto:kevin.rodgers@xxxxxxx] > Sent: 27 January 2005 15:10 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] conditional instruction vs. conditional expression > > What are the advantages and disadvantages of passing a string > parameter > via a conditional instruction (XPath 1.0): > > <xsl:with-param name="content"> > <xsl:if test="mb3e:org_list/mb3e:org_code[@type='APPR' and > text()='ANSI']"> > <xsl:text>*</xsl:text> > </xsl:if> > </xsl:with-param> > > vs. via a conditional expression (XPath 2.0): > > <xsl:with-param name="content" > select="if (mb3e:org_list/mb3e:org_code[@type='APPR' and > text()='ANSI']) > then '*' > else ''"/> > > Thanks, > -- > Kevin Rodgers
