Re: Newbie - trying to extract specific values from XM
Hi Julian, > I have a long html file (see http://hq.tvw.net/template.html) > that includes a mass of merge codes from an old program. What I'd suggest is that you set up a key that retrieves the <Answer> element with a particular name. The key would look like: <xsl:key name="answers" match="Answer" use="@name" /> Then anywhere in the template where you have something like: «SETstd» you can use, instead: <xsl:apply-templates select="key('answers', 'SETstd')" /> The call to the key() function retrieves the <Answer> element whose name attribute has the value 'SETstd'. The <xsl:apply-templates> instruction applies templates to it. You then need templates that look like: <xsl:template match="Answer[@name = 'SETstd']"> SETstd is <xsl:value-of select="TFValue" /> </xsl:template> to get the appropriate text for the given answer. You can similarly use the key to retrieve the <Answer> elements where they're tested in IF statements within the current template. For example: «IF Setstd = FALSE» can be replaced by: <xsl:if test="key('answers', 'SETstd')/TFValue = 'false'"> Note that you have to do a bit of work to identify what descendant of the <Answer> element you need to look at in these tests, since it depends on the structure of the XML that you're using (whether the <Answer> element contains a <RptValue> element, a <TFValue> element, a <TextValue> element or something else. The key is a very efficient way to get at the <Answer> elements based on their name. Given that you already have the HTML template written in a 'pull' way, I think that this approach is going to be easier to use than a more 'push' method of applying templates to all the <Answer> elements and just having templates to match them.
