Subject: [xsl] Effects of white space between xml elements From: Nat Wilson <beltramie@xxxxxxxxx> Date: Mon, 23 Feb 2009 16:32:40 -0600 |
Does white space between elements of an xml document effect the output of a transformation of that document? I noticed that sometimes adding a new line in between the closing tag of one element and the opening tag of the next element changes my output, even though I am working with the same stylesheet. I thought that white space in an XML document was ignored during the transformation; that the only thing that will effect the output are the on/off tags and how they are nested in each other. If tags are nested properly, shouldn't white space and new lines in between elements be irrelevant? Here is an example of what I mean. Stylesheet element I am using: <xsl:template match="HERB/actions"> <p></p> <xsl:text>Effects: </xsl:text> <xsl:for-each select="child::node()"> <xsl:apply-templates/> <xsl:text>, </xsl:text> </xsl:for-each> <xsl:text>.</xsl:text> </xsl:template> 2 inputs Im using with this stylesheet, only different in their spacing between elements: Input 1: <chemistry><activeIngredient>Coniine</activeIngredient></chemistry> <actions><effect>antispasmodic</effect><effect>sedative</effect><effect>poison antidote</effect></actions> Output 1: "Effects: antispasmodic, sedative, poison antidote," Input 2 (has new lines separating the <effect> elements but nested the same> <chemistry><activeIngredient>Coniine</activeIngredient></chemistry> <actions> <effect>antispasmodic</effect> <effect>sedative</effect> <effect>poison antidote</effect> </actions> Output 2: "Effects: , antispasmodic, , sedative, , poison antidote, ," Why would it add this extra comma in the output list? Is it that I am writing the xsl element incorrectly? Is there some aspect of XML that I am totally missing? And if so, are there other times that the output can be different due to more/less white space between elements?
