I am new to xslt and have done some research and read a brief book and looked at many examples but I'm afraid I just don't get it. I've only done simple procedural coding before and I guess I'm missing something. I understand a very basic example but when I try to transform my own data I am completely lost. Boo hoo hoo. It is soooo frustrating knowing that I don't it! I really feel like a hack :(
Anyway, I generated the following XML from a table in MS Word. The table ID and Row and Column IDs of each cell are given so it is possible to know how things relate to each other.
Now I want to present the data in a pick list and basically want to:
1. Filter the data on, say [Name='p_fld_parent_ref' and Value='RM12']. The data with the matching "rows" (i.e. all the nodes with the matching RowID) is what I want.
2. I also want to sort that filtered data on the column (cell) with name [p_fld_date_received]. I included a #dateSerial attribute specifically to make the sorting easier.
In the example data I should get any "rows" of data with a parent reference of 'RM12' sorted by date received. I want to use the data in the [p_fld_quantity_available] cell.
I've wasted about 3 days on this and gotten absolutely nowhere. Normally you start to get somewhere but with xslt I've gotten nowhere. Strange.
Here is one "row" of my data (sorry, I pasted the XML but don't know how to format it for reading - can someone let me know how to display it in the right format? Thanks.):

Assuming that each row is represented by a <Data> element (incidentally, you're missing the end tag of the <Data> element in this sample), this should do the filter/sorting part:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="Root">
<Root>
<xsl:apply-templates
select="Data[Element[Name='p_fld_parent_ref']/Value='RM12']">
<xsl:sort select="Element[Name='p_fld_date_received]/Value/#dateSerial" />
</xsl:apply-templates>
</Root>
</xsl:template>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
You'll need to define a template for how you want your <Data> elements presented, and probably something other than simply re-creating the Root element as I've done above. Something as simple as this might do the trick, if you just want to output text:
<xsl:template match="Data">
<xsl:text>Item no.:</xsl:text>
<xsl:value-of select="Element[Name='p_fld_item_no']/Value" />
<xsl:text> Quantity available:</xsl:text>
<xsl:value-of select="Element[Name='p_fld_quantity_available']/Value" />
<xsl:text>
</xsl:text><!-- New line -->
</xsl:template>
This isn't a complete solution, but hopefully it'll give you enough pointers to figure out the rest.

Assume my xml input is a MFMATR element with a few child elements, such as: TRLIST, INTRO, and SBLIST -- in that document order. I am converting to HTML.
I have a template that matches on the MFMATR element, and wants to run xsl:apply-templates on the 3 child elements, but I want INTRO to be processed first (listed first in the HTML). The other two (TRLIST and SBLIST) should keep their relative document order, as long as INTRO comes before both of them.
So I'd like to run <xsl:apply-templates select="INTRO, *"> but not have INTRO matched twice. (Using this syntax with xsl 3.0 causes dupes for me.) I also don't want to explicitly list every tag in the select expression, so unknown tags will still be processed.
A 2nd real life example is this: <xsl:apply-templates select="TITLE, CHGDESC, *"/>. Again, right now that is causing dupes I don't want.
I am using Saxon.
So I'd like to run <xsl:apply-templates select="INTRO, *"> but not have INTRO matched twice
Try:
<xsl:apply-templates select="INTRO, * except INTRO">
This seems to work. If someone has a better answer, let me know and I will change it.
There is no DRY violation here -- no repeated element names or variable names. I want it to look clean at all the call sites I will have.
It seems idiomatic to me since the function was pulled from w3's own website!
<xsl:template match="MFMATR">
<!-- Process INTRO first, no matter where it appears -->
<xsl:variable name="nodes" select="INTRO, *"/>
<xsl:apply-templates select="kp:distinct_nodes_stable($nodes)"/>
</xsl:template>
<xsl:template match="INTRO">
<xsl:variable name="nodes" select="TITLE, CHGDESC, *"/>
<xsl:apply-templates select="kp:distinct_nodes_stable($nodes)"/>
</xsl:template>
<!-- Discard duplicate elements in $seq, but keep their ordering -->
<!-- Adapted from https://www.w3.org/TR/xpath-functions/#func-distinct-nodes-stable -->
<xsl:function name="kp:distinct_nodes_stable" as="node()*">
<xsl:param name="seq" as="node()*"/>
<xsl:sequence select="fold-left($seq, (),
function($foundSoFar as node()*, $this as node()) as node()* {
if ($foundSoFar intersect $this)
then $foundSoFar
else ($foundSoFar, $this)
}) "/>
</xsl:function>
I am a novice XSLT developer. I have been asked to fix an issue on a project where the original developer is no longer with us. In the XSLT, there is a for-each loop using a key and a count
<xsl:for-each select="ns0:BOM[count(. | key('subsat', ns0:BomText01)[1]) = 1][ns0:BomText01]">
...
This is the key:
<xsl:key name="subsat" match="ns0:Parts/ns0:BOM[ns0:FindNum!='0']" use="ns0:BomText01" />
In the XML file being transformed, there are two sibling nodes that represent sub-parts:
<ns0:BOM referentId="10000:65091335:65359080">
<ns0:BomText01>3069260-303-SUB0027</ns0:BomText01>
<ns0:ItemNumber>My_part_1</ns0:ItemNumber>
<ns0:ItemType>Part</ns0:ItemType>
<ns0:Qty>67</ns0:Qty>
</ns0:BOM>
<ns0:BOM referentId="10000:65102551:86713230">
<ns0:BomText01>3069260-303-SUB0027</ns0:BomText01>
<ns0:ItemNumber>My_part_2</ns0:ItemNumber>
<ns0:ItemType>Part</ns0:ItemType>
<ns0:Qty>67</ns0:Qty>
</ns0:BOM>
However, the loop is only picking up the first node (My_part_1). I suspect it's because of the count=1 but I really don't know. And I don't know how to modify it. Ideas? If I need to include more data, let me know.
Assuming that the relevant part of your XSLT looks something like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns0="ns0" version="1.0">
<xsl:key name="subsat" match="ns0:BOM[ns0:FindNum!='0']" use="ns0:BomText01"/>
<xsl:template match="ns0:Parts">
<xsl:for-each
select="ns0:BOM[count(. | key('subsat', ns0:BomText01)[1]) = 1][ns0:BomText01]">
<xsl:value-of select="."/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
It will only print the first of the elements because it is selecting the BOM elements which have an unique BomText01 value. That's the expected result.
If the BomText01 is an ID field (as it seems it is) and you expected to get both result (perhaps, because their ItemNumber contains different values), the error is possibly in your source (which assigned equal IDs when it should not have done so).
If you change one of those values in the source, you should be able to select both and verify this.
i'm new with XSL and have tried to look through all the examples on here but none match my problem.
i have a sort order list of movies (order from left to right)
<movies>movieF,movieC,movieG</movies>
now i want to take that sort order list and sort on top of this huge movies list of mine
<moviesList>
<movie>movieA</movie>
<movie>movieB</movie>
<movie>movieC</movie>
<movie>movieD</movie>
<movie>movieE</movie>
<movie>movieF</movie>
<movie>movieG</movie>
<movie>movieH</movie>
</moviesList>
result i want:
<moviesList>
<movie>movieF</movie>
<movie>movieC</movie>
<movie>movieG</movie>
<movie>movieA</movie>
<movie>movieB</movie>
<movie>movieD</movie>
<movie>movieE</movie>
<movie>movieH</movie>
</moviesList>
would someone please give me some guidance of how to achieve such thing. i've tried to create a variable $sortlist, and then add delimited character around and then use substring-before trick on the sort. result is my sorted list did show up on top before the rest of the movies but it's not on the right order. please help.
Try this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="sortlist" select="';movieF;movieC;movieG;'"/>
<xsl:template match="moviesList">
<xsl:copy>
<xsl:for-each select="*[contains($sortlist, concat(';',.,';'))]">
<xsl:sort select="substring-before($sortlist,concat(';',.,';'))" />
<xsl:copy-of select="."/>
</xsl:for-each>
<xsl:copy-of select="*[not(contains($sortlist, concat(';',.,';')))]"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Notice, I didn't use string-length to sort, I just used the string itself. XSLT1.0 can sort alphabetically instead of numerically, which would place 14 above 7, resulting in the order movieF, movieG, movieC.
It actually uses the portion of the list of movie names that comes before each one as the sort key; alphabetically speaking, ;movieF; comes before ;movieF;movieC;, therefore it'll place movieC above movieG when sorting.
Personally I tend to avoid using commas as a separator as they can be used in some names, such as 'Crouching Tiger, Hidden Dragon'. A semicolon's far less likely, but you could use any character you like as long as it's not one that appears in a movie name.
I've been trying to wrap my head around using XPath and XQuery for this with the help of some previous posts to no avail. Right now I have null child nodes which should just default to ordering at the end of a sort but unfortunately, the sort does not occur at all on these null nodes. As a result I have been trying to find a way to set them to zero during the sorting section. Here is a sample below:
<xsl:for-each select="MyItems/Item">
<xsl:sort select="Order/obj/Number" order="ascending">
I want to do something similar to an inline if statement as part of the sort like in C# below:
foreach(item in MyItems.OrderBy(Order/obj/Exists != false ? Order/obj/Number : 0)
I was using these links: dynamic xpath expression and XSLT transfom with inline if statements to try and understand but I'm still not getting it. Any help is appreciated. I need the solution in XSLT.
Your situation is unclear as you say nothing about the contents of your XML or the nature of your XSLT transform. But it sounds something like you have Item elements with no Order/obj/Number elements to sort on?
I would code that something like this
<xsl:template match="/root">
<xsl:copy>
<xsl:apply-templates select="MyItems/Item[Order/obj/Number]">
<xsl:sort select="Order/obj/Number" />
</xsl:apply-templatesh>
<xsl:apply-templates select="MyItems/Item[not(Order/obj/Number)]" />
</xsl:copy>
</xsl:template>
<xsl:template select="MyItems/Item">
<xsl:copy-of select="current()" />
</xsl:template>
Talking about "null nodes" isn't helpful. It's not a well-defined term. Show us your XML, your desired results and your actual results, and we can help you.
What should happen is that if the select expression in xsl:sort returns an empty sequence/node-set, the effective sort key is a zero-length string, so these items sort before any others (assuming ascending order).
I've been tasked with putting together a book (using XSL FO) from a number of XML-files, now I'm trying to number the figures in this book (simple numbering, no resets at chapters or whatever), my naive approach was to do this
<xsl:template match="figure">
<fo:block xsl:use-attribute-sets="figure">
.. stuff to deal with images ..
<fo:block xsl:use-attribute-sets="figure-caption">
Figure <xsl:number level="any"/>: <xsl:apply-templates/>
</fo:block>
<fo:block xsl:use-attribute-sets="figure-caption">
</xsl:template>
I have an aggregate XML file which selects the files to use using the document() function like so:
<xsl:template match="include">
<xsl:apply-templates select="document(#src)"/>
</xsl:template>
Now, my problem is that number seems to always only count the instances in the current file, which is not what I want (currently, there's only one or two images per file, resulting in all figures being 'Figure 1' or 'Figure 2').
I've considered two approaches, both being essentially two-pass XSLT. First, the straightforward approach, generate an intermediary XML containing the entire book using an identity transform, which I'm reluctant to do for other reasons.
Second, using node-set() extension, which I tried like this
<xsl:template match="include">
<xsl:apply-templates select="ext:node-set(document(#src))"/>
</xsl:template>
but this produced the same result.
Any ideas? Perhaps something which isn't a two-pass transformation? Any help would be greatly appreciated.
The two -pass approach is the more logical and robust one.
One-pass approach is very challenging. One can provide an expression in the value attribute of <xsl:number> and this can be used to sum the "local number" with the maximum accumulated number so far from all previous documents.
However, this requires sequencing the documents (which is something bad in a functional language) and this only works for a flat numbering scheme. In case hierarchical numbering is used (3.4.2), I don't see an easy way to continue from the max number of a previous document.
Due to this considerations, I would definitely merge all documents into one before numbering.
I will also use a two phase transformation. But just for fun, with one include level and no repetition, this stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="vIncludes" select="//include"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="include">
<xsl:apply-templates select="document(#src)"/>
</xsl:template>
<xsl:template match="picture">
<xsl:variable name="vRoot" select="generate-id(/)"/>
<xsl:variable name="vInclude"
select="$vIncludes[
$vRoot = generate-id(document(#src))
]"/>
<xsl:copy>
<xsl:value-of
select="count(
document(
(.|$vInclude)/preceding::include/#src
)//picture |
(.|$vInclude)/preceding::picture
) + 1"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
With this input:
<master>
<include src="child3.xml"/>
<block>
<include src="child1.xml"/>
<picture/>
</block>
<include src="child2.xml"/>
<picture/>
</master>
And 'child1.xml'
<child1>
<picture/>
</child1>
And 'child2.xml'
<child2>
<picture/>
</child2>
And 'child3.xml'
<child3>
<picture/>
</child3>
Output:
<master>
<child3>
<picture>1</picture>
</child3>
<block>
<child1>
<picture>2</picture>
</child1>
<picture>3</picture>
</block>
<child2>
<picture>4</picture>
</child2>
<picture>5</picture>
</master>
You could use an ancillary XML documentto keep track of the last figure number and load that file as a document from your stylesheet. Or, if you do not want to manage two output files from the same stylesheet (the "real" FOP output and the figure counter) you can simply load the previous chapter's FOP file and look for the MAX of the figure-caption.
Or you could pass the last figure number as a parameter with default zero and pass the parameter on the command line. The value of this parameter resulting from the parsing of the previous one in the ascending resulting document order.
All these alternatives suppose you are running the transformations in sequence in source document ascending order.
A more structured and robust solution would be to manage transverse document sections such as indices, table of contents and table of figures in as many separate FO documents that would be generated in a "second pass" run with their own XSLT.
I think I would do a prepass which outputs summary information about all the documents in a single XML file, and then use this as a secondary input to the number calculation. The summary information in your case might just be a count of how many figures each document contains, but in many cases it can be useful to hold other information as well such as the IDs of sections that will act as the target of hyperlinks.
