[xsl] XPath behaves differently when opened by document()

[Jack Bush <netbeansfan@xxxxxxxxxxxx>]

Hi All,
B 
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:
B 
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[@id='content']/ns:table[@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 c c <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.
B 
( 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:
B 
7
<xsl:for-each select="document($FILE_LIST_PARAM)/ns:html/ns:body/ns:div">
B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B
 B B B B B B B B B B B B  to
7 <xsl:for-each
select="document($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">
B 
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.
B 
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).
B 
Hope I haven't confused
everyone already.

Any suggestion would be much appreciated.
Thanks in
advance,
Jack
