How to get the value of len as 4 and not as 4.0, OR, Is there another way I can find the length of the array using the jelly it-self and use it from there?
<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
<g2:evaluate>
var transport = ["cars", "trains", "buses", "bikes"];
var len = transport.length; <!-- len = 4 -->
</g2:evaluate>
<p>len = $[len]</p> <!-- len = 4.0 -->
<j2:forEach begin="0" end="$[len]" step ="1">
<p>Hello</p>
</j2:forEach>
</j:jelly>
I just get one Hello as output, instead of 4 Hellos

I am coding with Ruby and I used Nokogiri and the method xpath to extrapole the "CONTENT" of the file
this is the code:
def extrapolate_error(xml)
doc = Nokogiri::XML(File.open(xml))
doc.xpath('//CONTENT')
end
and this is the result:
[#<Nokogiri::XML::Element:0x1c5ba78 name="CONTENT" children=[
#<Nokogiri::XML::Text:0x1c5b940 "\n">,
#<Nokogiri::XML::Element:0x1c5b8bc name="ComplexResponse" namespace=#<Nokogiri::XML::Namespace:0x1c5b88c prefix="dms" href="http://dmsmanagerservice">
attributes=[
#<Nokogiri::XML::Attr:0x1c5b874 name="ErrorCode" value="430">,
#<Nokogiri::XML::Attr:0x1c5b868 name="ErrorDescription" value="null : PrivacyUE Mancante">,
#<Nokogiri::XML::Attr:0x1c5b85c name="Return" value="false">]
children=[#<Nokogiri::XML::Text:0x1c5b118 "\n">,
#<Nokogiri::XML::Element:0x1c5b094 name="Element" namespace=#<Nokogiri::XML::Namespace:0x1c5b88c prefix="dms" href="http://dmsmanagerservice">
attributes=[#<Nokogiri::XML::Attr:0x1c5b058 name="Name" value="DMSVERSION">]
children=[#<Nokogiri::XML::Text:0x1c5abe4 "2.7">]>,
#<Nokogiri::XML::Text:0x1c5aaac "\n">]>,
#<Nokogiri::XML::Text:0x1c5a974 "\n">]>]
Now I need to enter in it and select some attributes.
In the specific I need this:
name="ErrorCode" value="430"
name="ErrorDescription" value="null : PrivacyUE Mancante"
I do not know how to procceed. Can you help me?
The following should work for you assuming the dms namespace is always the same
doc.xpath('//CONTENT/dms:ComplexResponse', dms: 'http://dmsmanagerservice')
.xpath('#ErrorCode | #ErrorDescription')
.each_with_object({}) do |e,obj|
obj[e.name] = e.text
end
#=> {"ErrorCode"=>"430", "ErrorDescription"=>"null : PrivacyUE Mancante"}
You already understand how you got to //CONTENT so from there we use dms:ComplexResponse to navigate deeper but since this is namespaced we have to provide the namespace reference e.g. dms: 'http://dmsmanagerservice'.
Then we select the attributes we are interested in #ErrorCode and #ErrorDescription.
In XPath the pipe | means UNION (think AND) so we want to select both.
Then we are just building a Hash using the name as the key and the text as the value.
XPath Cheatsheet - Useful resource if you need additional reference
Update
You asked about conditionals so this is what I would propose
ndoc = Nokogiri::XML(doc)
namespaces = ndoc.collect_namespaces
response = ndoc.xpath("//CONTENT/dms:ComplexResponse", namespaces)
if response.xpath("self::node()[#ErrorCode != '' and #ErrorDescription != '']").any?
response.xpath("#ErrorCode | #ErrorDescription")
.each_with_object({}) do |e,obj|
obj[e.name] = e.text
end
else
response.xpath('dms:Element/#Name | dms:Element/text()',namespaces)
.each_slice(2)
.map {|s| s.map(&:text)}.to_h
end
This checks to see if there is an ErrorCode and and ErrorDescription if so then Hash as originally proposed. If Not then it returns all the dms:Elements as a Hash so {"DMSVERSION"=>"2.7"} in this case Functional Example
I have following Structure: I am trying to build a robust method to extract the elements of FT1_19_0 of the FT1_19 Tag in the order they appear. However
in my results the elements are rearranged. How can i get my result in correct order.

The ordering is working correctly, but it's retuning all <Concelho> elements.
You need to do the sort, then filter:
let $foo :=
for $x in doc("Camaras.xml")/Portugal/Concelho
order by xs:integer($x/Habitantes/Habitante[#Ano = "2001"]) descending
return $x
return $foo[ position() <= 5 ]
I'm parsing a simple XML file to create a flat text file from it. The desired outcome is shown below the sample XML. The XML has sort of a header-detail structure (Assembly_Info and Part respectively), with a unique header node followed by any number of detail record nodes, all of which are siblings. After digging into the elements under the header, I can't then find a way back 'up' to then pick up all the sibling detail nodes.
XML file looks like this:
<?xml version="1.0" standalone="yes" ?>
<Wrapper>
<Record>
<Product>
<prodid>4094</prodid>
</Product>
<Assembly>
<Assembly_Info>
<id>DF-7A</id>
<interface>C</interface>
</Assembly_Info>
<Part>
<status>N/A</status>
<dev_name>0000</dev_name>
</Part>
<Part>
<status>Ready</status>
<dev_name>0455</dev_name>
</Part>
<Part>
<status>Ready</status>
<dev_name>045A</dev_name>
</Part>
</Assembly>
<Assembly>
<Assembly_Info>
<id>DF-7A</id>
<interface>C</interface>
</Assembly_Info>
<Part>
<status>N/A</status>
<dev_name>0002</dev_name>
</Part>
<Part>
<status>Ready</status>
<dev_name>0457</dev_name>
</Part>
</Assembly>
</Record>
</Wrapper>
For each Assembly I need to read the values of the two elemenmets in Assembly_Info which I do successfully. But, I then want to read each of the Part records that are associated with the Assembly. The objective is to 'flatten' the file into this:
prodid id interface status dev_name
4094 DF-7A C N/A 0000
4094 DF-7A C Ready 0455
4094 DF-7A C Ready 045A
4094 DF-7A C N/A 0002
4094 DF-7A C Ready 0457
I'm attempting to use findnodes() to do this, as that's about the only tool I thought I understood. My code unfortunately reads all of the Part records from the entire file foreach Assembly--since the only way I've been able to find the Part nodes is to start at the root. I don't know how to change 'where I am', if you will; to tell findnodes to begin at current parent. Code looks like this:
my $parser = XML::LibXML -> new();
my $tree = $parser -> parse_file ('DEMO.XML');
for my $product ($tree->findnodes ('/Wrapper/Record/Product/prodid')) {
$prodid = $product->textContent();
}
foreach my $assembly ($tree->findnodes ('/Wrapper/Record/Assembly')){
$assemblies++;
$parts = 0;
for my $assembly ($tree->findnodes ('/Wrapper/Record/Assembly/Assembly_Info')) {
$id = $assembly->findvalue('id');
$interface = $assembly->findvalue('interface');
}
foreach my $part ($tree->findnodes ('/Wrapper/Record/Assembly/Part')) {
$parts++;
$status = $part->findvalue('status');
$dev_name = $part->findvalue('dev_name');
}
print "Assembly No: ", $assemblies, " Parts: ",$parts, "\n";
}
How do I get just the Part nodes for a given Assembly, after I've gone down to the Assembly_Info depths? There is quite a bit I'm not getting, and I think a problem may be that I'm thinking of this as 'navigating' or moving a cursor, if you will. Examples of XPath path expressions have not helped me.
Instead of always using $tree as the starting point for the findnodes method, you can use any other node, especially also child nodes. Then you could use a relative XPath expression. For example:
for my $record ($tree->findnodes('/Wrapper/Record')) {
for my $assembly ($record->findnodes('./Assembly')) {
for my $part ($assembly->findnodes('./Part')) {
}
}
}
I have the following XML:

</office:meta>
</office:document-meta>
</gnm:Workbook>
And am trying to read the office:document-meta node to extractthe various elements below it (dc:creator, meta:creation-date, etc.)
The following code:
$xml = simplexml_load_string($gFileData);
$namespacesMeta = $xml->getNamespaces(true);
$officeXML = $xml->children($namespacesMeta['office']);
var_dump($officeXML);
echo '<hr />';
gives me:
object(SimpleXMLElement)[91]
public 'document-meta' =>
object(SimpleXMLElement)[93]
public '#attributes' =>
array
'version' => string '1.1' (length=3)
public 'meta' =>
object(SimpleXMLElement)[94]
but if I try to read the document-meta element using:
$xml = simplexml_load_string($gFileData);
$namespacesMeta = $xml->getNamespaces(true);
$officeXML = $xml->children($namespacesMeta['office']);
$docMeta = $officeXML->document-meta;
var_dump($docMeta);
echo '<hr />';
I get
Notice: Use of undefined constant meta - assumed 'meta' in /usr/local/apache/htdocsNewDev/PHPExcel/Classes/PHPExcel/Reader/Gnumeric.php on line 273
int 0
I assume that SimpleXML is trying to extract a non-existent node "document" from $officeXML, then subtract the value of (non-existent) constant "meta", resulting in forcing the integer 0 result rather than the document-meta node.
Is there a way to resolve this using SimpleXML, or will I be forced to rewrite using XMLReader? Any help appreciated.
Your assumption is correct. Use
$officeXML->{'document-meta'}
to make it work.
Please note that the above applies to Element nodes. Attribute nodes (those within the #attributes property when dumping the SimpleXmlElement) do not require any special syntax to be accessed when hyphenated. They are regularly accessible via array notation, e.g.
$xml = <<< XML
<root>
<hyphenated-element hyphenated-attribute="bar">foo</hyphenated-element>
</root>
XML;
$root = new SimpleXMLElement($xml);
echo $root->{'hyphenated-element'}; // prints "foo"
echo $root->{'hyphenated-element'}['hyphenated-attribute']; // prints "bar"
See the SimpleXml Basics in the Manual for further examples.
I assume the best way to do it is to cast to array:
Consider the following XML:
<subscribe hello-world="yolo">
<callback-url>example url</callback-url>
</subscribe>
You can access members, including attributes, using a cast:
<?php
$xml = (array) simplexml_load_string($input);
$callback = $xml["callback-url"];
$attribute = $xml['#attributes']['hello-world'];
It makes everything easier. Hope I helped.
