Hi guys,
This is related to a query I had some weeks ago (in case it sounds
familiar to someone).
I am processing a document that comes from a database. Its structure is
that it has an <Institution> document element. The <Institution>
element has <Module>, <Course>, and <Student> elements.
The <Student> element contains - amongst other things - a <HUSIC>
element (simple type and key from the student table), an <FNAMES>
element (simple type), and an <Instance> element.
The <Instance> element has, amongst other things, a <REDUCEDI> element.
I'm processing the source data using <xsl:for-each> elements in the xsl.
The current code I am writing is withing such and element as follows:
<xsl:for-each select="s0:Institution/s0:Student">
...
</xsl:for-each>
In the xsl, I want to express the notion that an <FNAMES> element should
only be included where there exists a <REDUCEDI> element in an any
<Instance> below the current <Student> having a value of '00' or '04'.
This should result in the exclusion of this element for 45 students.
First of all, I tried the following:
<xsl:for-each select="s0:Institution/s0:Student">
...
<xsl:if test="s0:Instance/REDUCEDI[.='00' or .='04'">
<FNAMES>
...
</FNAMES>
</xsl:if>
...
</xsl:for-each>
This resulted in an <FNAMES> element being present for every student
including the 45 whom we knew were code '03' in their associate
Instance/REDUCEDI elements.
Next I tried:
<xsl:for-each select="s0:Institution/s0:Student">
...
<xsl:if
test="/s0:Institution/s0:Student[s0:HUSID=current()]/s0:Instance/s0:REDU
CEDI[.='00' or .='04']">
<FNAMES>
...
</FNAMES>
</xsl:if>
...
</xsl:for-each>
This resulted in no students having an <FNAMES> element. I.e. the
output document never contained an <FNAMES> element for a <Student>
Can someone spot where my XPATH statements are going astray, please?
Many thanks,
Peter
