Subject: RE: [xsl] Filtering XML with XSL From: "Steve Gold" <Steve@xxxxxxxxxxxxx> Date: Thu, 6 Feb 2003 20:48:51 -0500 |
Sam, Let's go back to something you said early on in response to a suggestion about doing the transformation in JavaScript after a trip back up to the server. You said, "My xml is dynamically created". That is why you are trying to do the transformation client-side in the browser using JavaScript. What do you mean it is dynamically created? Like using XSQL or something? Maybe we need to look at doing your filter upon creation or passing the parameters in earlier in the process?

I think I misled you a little. My current XSL sheet accepts the parameters (when I hardcode them in the begining) without a problem and I am able to see the transformed data based on a certain parameter value. When I click on my event handlers that call the JavaScript nothing happens and no errors are displayed. It is supposed to reload the XSLT and feed it the new parameter values upon reload (like you mentioned about the use of XMLDocument and XSLDocument properties). So, I added alerts to the JavaScript and I see that the properties document.XMLDocument and navigator.XMLDocument are empty, their value is "undefined". Shouldn't I be seeing the XML sting in there? Sorry I am not very savvy at this but I am trying. Thanks again very much. -----Original Message----- From: owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx [mailto:owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx]On Behalf Of Charles White Sent: Thursday, February 06, 2003 1:26 AM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: [xsl] Filtering XML with XSL Hi Sam: It makes sense that you are getting a bunch of errors telling you the object doesn't exist, because the JScript engine is looking for objects named, for example, in the case of the filter function, the actual given name. But you have no id attribute assigned to the object, so the JScript processor can't find the object. So, as just one example, do this: <xsl:attribute name="id"><xsl:value-of select="@givenName"/></xsl:attribute> I added this to your SortByTemplate template, and the JScript engine was able to find the object and display the information okay. So, this is what the beginning of that template now looks like (I added a cursor style because it drives me crazy to see an onclick event with no hand cursor associated with the event source): <xsl:template name="SortByChoice"> <TR bgcolor="#FAEBD7"> <TD><font face="Verdana" size="1" color="black"><xsl:value-of select="@sn"/></font></TD> <TD><font face="Verdana" size="1" color="black"><xsl:attribute name="onclick">filter('<xsl:value-of select="@givenName" />');</xsl:attribute><xsl:attribute name="style">cursor:hand;</xsl:attribute><xsl:attribute name="id"><xsl:value-of select="@givenName"/></xsl:attribute><u><xsl:value-of select="@givenName"/></u></font></TD> ... The only change is the additional xsl:attribute that creates an id attribute. You could also have used attribute value templates, they're a bit cleaner in my view, but this will work. You'll need to follow this procedure whererever you have function calls.
