Hi,
Could anyone help me out with this. I have looked through the table generation stuff on the site but I think my problem is slightly different. I need to build a 2 column table from only some of the nodes in my node set. Here is an excerpt from my XML. <archive id="111111"> <product label="Product" group="1. Product" required="t">aaa</product> <title label="Title" group="1. Product" required="t">bbb</title> <client label="Client" group="1. Product" required="t">ccc</client> <brand label="Brand" group="1. Product" required="t">ddd</brand> <jobref label="Job Reference" group="2. TV" required="f">eee</jobref> <tape_no label="Tape Number" group="2. TV" required="f">fff</tape_no> <duration label="Duration" group="2. TV" required="t">ggg</duration> <agency label="Agency" group="3. Agency" required="t">hhh</agency> <producer label="Producer" group="3. Agency" required="t">i</producer> <director label="Director" group="3. Agency" required="f">j</director> </archive> I dont know the element names in advance and I dont know how many elements there will be. Also, I need to lay them out in groups. I.e. I start a table for group "1. Product", lay out all the rows, finish the table and start a new table for group "2. TV" etc. I was doing this initially using a key to select all elements in a group and the looping thru them with a for-each and using position() mod 2 = 1 and following-sibling::*[1] to lay out the first and second td. This worked fine but now I need to only pick elements where @required = 'f'. This causes problems with following-sibling because there is no gaurantee that the following-sibling will have @required = 'f'. I can test for this but if it doesnt, then all i can do is layout an empty cell - which I dont want. What I want is someway to move forward int eh loop sort of. Or, I want to build a new nodeset where @required = 'f'. I thought i was doing this with a key which had @required = 'f' in the predicate but It doesnt actually select only those nodes. It is selecing all the nodes. Here is my key. <xsl:key name="notreq1" match="/archive[1]/*[@required = 'f']" use="@group" /> Here is my current for loop. <xsl:for-each select="/archive/*[count(. | key('notreq1', @group)[1]) = 1]"> <xsl:if test="not(@required = 't'"> <table width="100%" align="center" border="0"> <tr><td> <xsl:value-of select="substring-after(../*[@group = current()/@group]/@group, '. ')"/> </td></tr> <xsl:for-each select="key('notreq1', @group)[@required = 'f'][not(position() = 0)]"> <xsl:sort select="@group" /> <xsl:when test="(position() mod 2) = 1"> <td><xsl:value-of select="."/></td> <xsl:choose> <xsl:when test="following-sibling::*[1]/@group = @group"> <xsl:with-param name="content" select="following-sibling::*[1]"/> </xsl:when> <xsl:otherwise> <td>EMPTY CELL</td> </xsl:otherwise> </xsl:choose> </xsl:if> </xsl:for-each> </xsl:if> </xsl:for-each> Can anyone see what I am trying to do? Basically, my problem is with the node set i am looping through. Is there some way I can loop through only nodes with @required = 'f'. I thought the key did this. I.e. I thought I could build a new node set with the key??? I will provide more info if needed. I am in very new territory here so any help would be muchly appreciated.
