Problem combining two XMLs using XSLT

[Stefan]

Hi there!

I'm very new to XML and XSLT, so while working i encountered the
following, probably very easy to solve, problem.

i've got 2 XML-files, which look like this:

LinesOfCode.xml:
<?xml version="1.0"?>
<component name="ORCA_Common">
<LOC-netto>2100</LOC-netto>
<LOC-blank>200</LOC-blank>
<LOC-comment>400</LOC-comment>
<LOC>2700</LOC>
<Comment-netto>20%</Comment-netto>
</component>

CodeCoverage.xml:
<?xml version="1.0"?>
<component name="ORCA_Common">
<Coverage>50%</Coverage>
</component>

Both should be combined to a "component.xml", lookinf like this:
<?xml version="1.0"?>
<component name="ORCA_Common">
<LOC-netto>2100</LOC-netto>
<LOC-blank>200</LOC-blank>
<LOC-comment>400</LOC-comment>
<LOC>2700</LOC>
<Comment-netto>20%</Comment-netto>
<Coverage>50%</Coverage>
</component>

so just adding the data of the one XML to the data of the other.

I wanted to use a primary source, referring to both files, looking like
this:
<?xml version="1.0"?>
<index>
<entry>LinesOfCode</entry>
<entry>CodeCoverage</entry>
</index>

and logically the document() funcition in the xsl-file.

Could you please tell me how to do this? i tried several times with
lots of different XSL-files, but nothing seems to work.

Thanks in advance!

Greets, Stefan

What are these entries, the names of the files without the suffix (e.g.
file name would be LinesOfCode.xml for the first entry)?

and logically the document() funcition in the xsl-file.

Well you could simply e.g.
<xsl:template match="entry">
<xsl:apply-templates select="document(concat(., '.xml'))/component" />
to process the component elements in the file the entry element points
to. Is that what you want to know, how to use the document function?

Here is an example stylesheet

<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xslutput method="xml" indent="yes" />

<xsl:template match="/index">
<components>
<xsl:apply-templates select="entry[position() mod 2 = 1]" />
</components>
</xsl:template>

<xsl:template match="entry">
<xsl:apply-templates select="document(concat(., '.xml'), /)/component">
<xsl:with-param name="secondFile"
select="concat(following-sibling::entry[1], '.xml')" />
</xsl:apply-templates>
</xsl:template>

<xsl:template match="component">
<xslaram name="secondFile" />
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
<xsl:apply-templates select="document($secondFile,
/)/component[@name = current()/@name]/node()" />
</xsl:copy>
</xsl:template>

<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
</xsl:template>

</xsl:stylesheet>

I assumed your index file would have several entry elements where each
pair has to be processed together. Not sure if that is what you need.

Hi Stefan,

this is a typical merging-task.

I have not an XSLT-solution,
but with the product <xml>cmp (http://www.xmlcmp.com) you can solve
such tasks
and even much more complicated merging tasks.

For merging with <xml>cmp you need a basic-control-file and a
merge-control-file.

The basic-control-file (cmp1.xml) for your example would be:

<?xml version="1.0" encoding="UTF-8"?>
<component ident_att_name="true" >
<LOC-netto cmp_text="true" />
<LOC-comment cmp_text="true" />
<LOC cmp_text="true" />
<Coverage cmp_text="true" />
<Comment-netto cmp_text="true" />
<LOC-blank cmp_text="true" />
</component>

The merge-control-file (merge1.xml) would be:

<?xml version="1.0" encoding="UTF-8"?>
<merge>
<identity path='/component' merge='333' >
<value path='/LOC-netto' merge='3332' />
<value path='/LOC-comment' merge='3332' />
<value path='/LOC' merge='3332' />
<value path='/Coverage' merge='3332' />
<value path='/Comment-netto' merge='3332' />
<value path='/LOC-blank' merge='3332' />
</identity>
</merge>

The merge-attributes contain the merging-rules.
You can define very detailed merging-rules.
For further informations about these merging rules look at
http://www.xmlcmp.com.

Merging the two files:

$ xmlmerge.sh cmp1.xml merge1.xml example1a.xml example1b.xml >
result1.xml

Content of result-file (result1.xml):

<component name='ORCA_Common'>
<LOC-netto>2100</LOC-netto>
<LOC-blank>200</LOC-blank>
<LOC-comment>400</LOC-comment>
<LOC>2700</LOC>
<Comment-netto>20%</Comment-netto>
<Coverage>50%</Coverage>
</component>
