Subject: Re: [xsl] error:XSLT Stylesheet (possibly) contains a recursion. From: Abel Braaksma <abel.online@xxxxxxxxx> Date: Sat, 01 Dec 2007 16:07:52 +0100 |
Hi, i'm trying to do the following thing: I need to display a string until the last occurance of the space character.So if I would have "this is a news" i would need to display "this is a". I am using xslt1.0 and I tried doing the following:
<xsl:template name="extract"> <xsl:param name="text"/> <xsl:variable name="length" select="string-length($text)"/> <xsl:choose> <xsl:when test="substring($text,$length-1,$length)=' ' "> <xsl:value-of select="substring($text,1,$length-1)"/> </xsl:when> <xsl:otherwise> <xsl:call-template name="extract"> <xsl:with-param name="text" select="substring($text,1,$length-1)"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template>
basically I check if the last char of the string is space, display the text minus last char, otherwise, test again with text minus the last char. I get the error Error during XSLT transformation: XSLT Stylesheet (possibly) contains a recursion. I don't see why it would be interpreted as a infinit loop since the text keeps getting smaller.
