Hi, Problem to resolve: --------------------------------------------------- > A very interesting problem has been posted on the XSL list. How would we > resolve it in DSSSL.

My problem is how to create the `href' > attribute of the output element `a', in particular how to concat the > constant string "http://www.frob.org/search?type=simple&key=" and the > content of the `key' input element. Solution 1: (XSL) ------------------------------------------------ ,----- | <xsl:template match="entry"> | <a> | <xsl:attribute name="href"> | http://www.frob.org/search?type=simple&key= <xsl:value-of select="key"/> | </xsl:attribute> | <xsl:apply-templates match="description"/> | </a> | </xsl:template> `----- Solution 1: (DSSSL) ------------------------------------------------ If I got the question right, the following untested code fragment should do the trick using jade's sgml extension FOs. (element (entry key) (empty-sosofo)) (element entry (make element gi: "a" attributes: `(("href" ,(string-append "http://www.frob.org/search?type=simple&key=" (data (select (children (current-node) "key")))))) (process-children))) Solution 2: (DSSSL) ----------------------------------------------- OK I'll try this one: (element (entry key) (empty-sosofo)) (element entry (make link address: (url-address (string-append "http://www.frob.org/search?type=simple&key=" (data (select (children (current-node) "key")))) ) ) ) The premise to the solution is that the address object support the url type of address :-) and the other premise id that you use the "-t html" output format. stay tuned this is for soon... Note: I suppose Kai that your original document is in XML format, then with the addition of the following W3C header proposal you get a document rendered into html <?xml-stylesheet href="myscript.dsl" type="text/dsssl" media="screen,html"> or as soon as the rtf backend get this new address object <?xml-stylesheet href="myscript.dsl" type="text/dsssl" media="print,rtf"> or as soon as we have the MIF backend with this new address object: <?xml-stylesheet href="myscript.dsl" type="text/dsssl" media="print,mif"> other solutions? (why not a transformation based solution?) regards Didier PH Martin mailto:martind@xxxxxxxxxxxxx http://www.netfolder.com DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
