Subject: RE: [xsl] Converting embedded URLs int hot links via XSL From: David.Pawson@xxxxxxxxxxx Date: Mon, 19 Apr 2004 10:09:59 +0100 |
The regxlib site - has a reasonable search capability - search for https or just use this link: http://regxlib.com/Search.aspx?k=https Thanks for that. Less sure it helps now... unless someone tells me differently. INput <vs> <url> Test url string: 'http://www.yahoo.com' and one more url "https://www.yahoo.com"</url> <url>http://www.yahoo.com</url> part of xslt 2.0 stylesheet <xsl:template match="/vs/url"> <xsl:message> <xsl:value-of select="matches (., '(http|https|ftp)://((([a-z_0-9\-]+)+(([:]?)+([a-z_0-9\-]+))?)(@+)?)?(((((([ 0-1])?([0-9])?[0-9])|(2[0-4][0-9])|(2[0-5][0-5]))).(((([0-1])?([0-9])?[0-9]) |(2[0-4][0-9])|(2[0-5][0-5]))).(((([0-1])?([0-9])?[0-9])|(2[0-4][0-9])|(2[0- 5][0-5])))\.(((([0-1])?([0-9])?[0-9])|(2[0-4][0-9])|(2[0-5][0-5]))))|((([a-z 0-9\-])+.)+([a-z]{2}.[a-z]{2}|[a-z]{2,4})))(([:])(([1-9]{1}[0-9]{1,3})|([1-5 ]{1}[0-9]{2,4})|(6[0-5]{2}[0-3][0-6])))?(/)?$')"/> </xsl:message> </xsl:template> works fine on second usage, fails on first, since its not a match. tokenize seems about right, to find the preceding and following strings, which may then be used in substring before and after to extract the needed string. but saxon 7.9.1 seems not to match using <xsl:template match="/vs/url"> <xsl:message> <xsl:for-each select="tokenize (., '(http|https|ftp)://((([a-z_0-9\-]+)+(([:]?)+([a-z_0-9\-]+))?)(@+)?)?(((((([ 0-1])?([0-9])?[0-9])|(2[0-4][0-9])|(2[0-5][0-5]))).(((([0-1])?([0-9])?[0-9]) |(2[0-4][0-9])|(2[0-5][0-5]))).(((([0-1])?([0-9])?[0-9])|(2[0-4][0-9])|(2[0- 5][0-5])))\.(((([0-1])?([0-9])?[0-9])|(2[0-4][0-9])|(2[0-5][0-5]))))|((([a-z 0-9\-])+.)+([a-z]{2}.[a-z]{2}|[a-z]{2,4})))(([:])(([1-9]{1}[0-9]{1,3})|([1-5 ]{1}[0-9]{2,4})|(6[0-5]{2}[0-3][0-6])))?(/)?$')"> <xsl:value-of select="."/><xsl:text> ======== </xsl:text> </xsl:for-each> </xsl:message> </xsl:template> only printing out the full string. I'm also curious how I might add (escape) the single or double quotes prior to the url in the example. http://www.w3.org/TR/xmlschema-2/#nt-Punctuation seems not to include these? regards DaveP - DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
