Hi Wolfgang,
Thanks for responding to this threat.
I have made the following changes by removing the inner <xsl:for-each> which
lookup main source (works) and would like to focus on the outstanding issues:
1 <xsl:param name="FILE_LIST_PARAM" as="xs:string*" required="no" select="()"/>
2 <xsl:param name="COMPANY_NAME_PARAM"/>
3
4 <xsl:template match="/">
5 <employee-profile>
6 <company_name><xsl:value-of select="$COMPANY_NAME_PARAM"/></company_name>
7 <xsl:for-each select="document($FILE_LIST_PARAM)/ns:html/ns:body/ns:div">
//
secondary source
8
<xsl:apply-templates/>
// secondary source
9
</xsl:for-each>
// secondary source
10 </employee-profile>
11 </xsl:template>
12
13 <xsl:template name="finance_initialization" match="ns:html/ns:body/ns:div">
14 <financial_status>
15 <xsl:variable name="salary" select="//ns:p[ns:strong='Salary:']"/>
16 <xsl:apply-templates select="$salary"/>
17 <xsl:if test="empty($salary)">
18 <salary>Unknown</salary>
19 </xsl:if>
......
35 </financial_status>
36 </xsl:template>
37
38 <xsl:template name="finance_detail" match="ns:p[ns:strong='Salary:']">
39 <xsl:for-each select="ns:a">
40 <salary><xsl:value-of select="."/></salary>
41 </xsl:template>
..........
55 <xsl:template match="ns:p"/>
56
57 </xsl:stylesheet>
There are 2 URIs passed as parameter $FILE_LIST_PARAM to document(). ie
file:///E:/John Smith.xml & file:///E:/Jessica Brown.xml.
( a ) Data from other non-related nodes along the path are been picked up if
<xsl:apply-templates/> is used as seen on line 8, yet XPath queries on both
URIs/files have been unique. ie once only.
( b ) On the other hand, irrelevant data along the path to the referenced nodes
<p> are no longer being picked up (achieved desired effect) if line 8 is
replaced with <xsl:call-template> as recommended. However, the down side is
that
the data in each URIs/files are been picked up (appears to querried both
finance_initialization & finance_detail) 3 times.
In short, option ( a ) got the data correctly but also include junk ones while
(
b ) no longer captured junk yet it is getting triplicates data. As a result,
can
you explain where this undesireable looping repetitions have taken place and
how
to resolve it?
( c ) There are <xsl:apply-templates> used within both finance_initialization &
finance_detail templates. Is it necessary to change them over to
<xsl:call-template>?
( d ) What is the purpose of <xsl:template match="ns:p"/> on line 55 used for?
I
am not clear at what stage that finance_initialization & finance_detail are
call/run and in what order?
Many thanks again,
Jack

Subject: Re: [xsl] XPath behaves differently when opened by document()
If your stylesheet is meant to do some lookup in the secondary source based
on data in the primary source I recommend that you do not try to use
apply-templates for the lookup but switch to call-template, passing in
parameters taken from the primary document.

Hi All,
There appears to be 2 undesirable features/effects felt when opening
secondary
document using document() function in XSLT 2.0 (Saxon 9.1) on Windows XP.
Let's
examine the stylesheet in question as follows:
1 <xsl:param name="FILE_LIST_PARAM" as="xs:string*" required="no"
select="()"/>
2 <xsl:param name="COMPANY_NAME_PARAM"/>
3
4 <xsl:template match="/">
5 <employee-profile>
6 <company_name><xsl:value-of select="$COMPANY_NAME_PARAM"/></company_name>
7 <xsl:for-each select="document($FILE_LIST_PARAM)/ns:html/ns:body/ns:div">
//
secondary source
8 <xsl:for-each
select="/ns:html/ns:body/ns:div[(_at_)id='content']/ns:table[(_at_)class='sresults']/ns:tr/ns:td/ns:a">
// main source
9 <employee_name><xsl:value-of
select="substring-before(@title,',')"/></employee_name> // main source
10 <employee_address><xsl:value-of select="@href"/></employee_address> //
main
source
11 </xsl:for-each> // main source
12 <xsl:apply-templates/> // secondary source
13 </xsl:for-each> // secondary source
14 </employee-profile>
15 </xsl:template>
17
18 <xsl:template match="ns:html/ns:body/ns:div">
19 <financial_status>
20 <xsl:variable name="salary" select="//ns:p[ns:strong='Salary:']"/>
21 <xsl:apply-templates select="$salary"/>
22 <xsl:if test="empty($salary)">
23 <salary>Unknown</salary>
24 </xsl:if>
......
35 </financial_status>
36 </xsl:template>
37
38 <xsl:template match="ns:p[ns:strong='Salary:']">
39 <xsl:for-each select="ns:a">
40 <salary><xsl:value-of select="."/></salary>
41 </xsl:template>
..........
55 <xsl:template match="ns:p"/>
56
57 </xsl:stylesheet>
( i ) document() needs more specific detail XPath statement to lookup the
desire
node. Otherwise, the data for every single subnodes will be retrieved before
getting to target node. For instance, line 7 would include irrelevant data
that
is part of subnodes along the path of getting to the destination node.
( ii ) On the other hand, yet when providing specific XPath instruction would
appears to query every nodes under the specified branch which is preventing
their individual templates from being run altogether. Again, if line 7 were
to
changed from:
7 <xsl:for-each select="document($FILE_LIST_PARAM)/ns:html/ns:body/ns:div">
to
7 <xsl:for-each
select="document($FILE_LIST_PARAM)/ns:html/ns:body/ns:div/p">
or
<xsl:for-each select="document($FILE_LIST_PARAM)/ns:html/ns:body/ns:div//p">
where all the data is located in each <p> node but would no longer execute
line
18 - 55, which was the original working stylesheet used to open the same
document as primary source.
In addition, I am also having difficulty getting data (switching between
documents) from main and secondary documents using nested for-each loop
(line
7
- 11). The result is that only the outer loop (7, 12-13; refer to secondary
document) is being taken effect but not the internal loop (8 - 11; refer to
main
source).
Hope I haven't confused everyone already.
Any suggestion would be much appreciated.
Thanks in advance,
Jack
