My XML
<catalog>
<item Id="1">
<book id="b1">
</book>
<cd id="c1">
</cd>
</item>
<item Id="11">
<book id="b11">
</book>
<cd id="c11">
</cd>
</item>
</catalog>
what I have ..
ap.selectXPath("/catalog/item");
while ((result = ap.evalXPath()) != -1) {
if (vn.toElement(VTDNav.FIRST_CHILD, "item")) {
do {
//do something with the contnets in the item node
} while (vn.toElement(VTDNav.NEXT_SIBLING, "book"));
}
// move to the parent node to traverse the rest of the items
}
What I want is to get to the "cd" node.
In some of the examples I saw VTDNav.NEXT_CHILD but seems like is not available . Can anyone suggest how to get to the node I need to . For now I am managing to do it by getting to the FIRST_CHILD and then moving to the next sibling
if (vn.toElement(VTDNav.FIRST_CHILD, "book")) {
// Move to the next sibling
vn.toElement(VTDNav.NEXT_SIBLING, "cd");
}
Appreciate all your help
Regards
You should not need to have next child. What you look for is probably NEXT_SIBLING, after you call FIRST_CHILD...

I'm trying to get tag "" from xml below.
If i execute request like this:
WITH x(col) AS (select'<document xmlns="http://example.com/digital/back/" xmlns:ns2="http://example.com/digital/back/complexId" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="">
<header>
<docId>13a2f29a28b12ecb</docId>
<dt>2018-12-10T11:59:48.112+03:00</dt>
</header>
<pay>
<reqTransfer id="154638">
<source>
<card>
<virtualCardNum>4B74C1EE187</virtualCardNum>
<bsc>VISA</bsc>
</card>
</source>
</reqTransfer>
</pay>
</document>
'::xml)
SELECT xpath('/document/pay/reqTransfer/source/card/bsc/text()', col) AS bsc
FROM x;
I get {}, but if I relpace the document start tag
<document xmlns="http://example.com/digital/back/" xmlns:ns2="http://example.com/digital/back/complexId" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="">
with <document> or even <document xmlns="">, I get { VISA } - that is right.
What should I do to replace <document xmlns="..."> with <document> or get { VISA } without replacement?
If you are working with XML namespaces, they are worth mentioning in your Xpath queries too, i.e. use
SELECT xpath('/d:document/d:pay/d:reqTransfer/d:source/d:card/d:bsc/text()', col,
ARRAY[ARRAY['d', 'http://example.com/digital/back/']]) AS bsc

I only want to show the categoryid node and value if its not an empty guid. I've tried different formats but nothing worked. It keeps just printing the if statement as a string in the results. I read that you had to have an else condition as part of your code, can I just put an empty string there? I've looked through a few articles online about this and the msdn reference with no luck. For some reason it's evaluating my if statement.
declare #XML xml = N'
<books>
<book>
<title>Book 1</title>
<categoryid>00000000-0000-0000-0000-000000000000</categoryid>
<author>Chris</author>
<price>10</price>
</book>
<book>
<title>Book 2</title>
<categoryid>DF3D696D-B7A3-44A2-BC7D-1D45745C979B</categoryid>
<author>Spencer</author>
<price>20</price>
</book>
</books>';
select #XML.query(
'<books>
{
for $b in /books/book
return
<book>
{$b/title}
{$b/price}
if(not($b/categoryid = 00000000-0000-0000-0000-000000000000))
then {$b/categoryid}
else
</book>
}
</books>'
);
I think there were two issues.
1 - The conditional block needed to be enclosed in curly braces before the "if" and after the "else" ended.
2 - The empty guid value needed to be its own variable - I think within the condition it was treating it as a string.
I also had trouble getting the "not" operator to behave as expected, so I just reversed the condition to bypass that problem.
declare #XML xml = N'
<books>
<book>
<title>Book 1</title>
<categoryid>00000000-0000-0000-0000-000000000000</categoryid>

<price>10</price>

<book>
<title>Book 2</title>
<categoryid>DF3D696D-B7A3-44A2-BC7D-1D45745C979B</categoryid>
<author>Spencer</author>
<price>20</price>
</book>
</books>';
declare #emptyguid uniqueidentifier = '00000000-0000-0000-0000-000000000000'
select #XML.query('
<books>
{
for $b in /books/book
return
<book>
{$b/title}
{$b/price}
{
if($b/categoryid = sql:variable("#emptyguid")) then
()
else (
$b/categoryid
)
}
</book>
}
</books>

I'm getting struggle in looping the entries in data weaver. Below is the Input and the expected response.
Not sure how to make loop(I need to get RecordEntry and each entry with 'IndividualEntry') .
Input xml : Record entry tag in input xml is 3, but I might get many. So need to make a loop as dynamic.
<?xml version="1.0" encoding="UTF-8"?>
<Records>
<storenumber />
<calculated>false</calculated>
<subTotal>12</subTotal>
<RecordsEntries>
<RecordEntry>
<deliverycharge>30.0</deliverycharge>
<entryNumber>8</entryNumber>
<Value>true</Value>
</RecordEntry>
<RecordEntry>
<deliverycharge>20.0</deliverycharge>
<entryNumber>7</entryNumber>
<Value>false</Value>
</RecordEntry>
<RecordEntry>
<deliverycharge>1.0</deliverycharge>
<entryNumber>6</entryNumber>
<Value>false</Value>
</RecordEntry>
</RecordsEntries>
</Records>
Expected Response ( I'm expecting the below response)
<?xml version="1.0" encoding="UTF-8"?>
<orders>
<order>
<StoreID />
<Total>false</Total>
<IndividualEntry>
<Number>8</Number>
<DeliverCharge>30.0</DeliverCharge>
</IndividualEntry>
<IndividualEntry>
<Number>7</Number>
<DeliverCharge>20.0</DeliverCharge>
</IndividualEntry>
<IndividualEntry>
<Number>6</Number>
<DeliverCharge>1.0</DeliverCharge>
</IndividualEntry>
</order>
</orders>
My Data weaver Transformation as below
%dw 1.0
%output application/xml
---
{
orders: {
order: {
StoreID:payload.Records.storenumber,
Total: payload.Records.calculated,
IndividualEntry: payload.Records.RecordsEntries.*RecordEntry map {
Number:$.entryNumber,
DeliverCharge:$.deliverycharge
}
}
}
}
Currently I'm getting response as below ( I don't know how to make each Record entry as a IndividualEntry tag, and also here element tag is added in extra which is not required in my case)
<?xml version="1.0" encoding="UTF-8"?>
<orders>
<order>
<StoreID />
<Total>false</Total>
<IndividualEntry>
<element>
<Number>8</Number>
<DeliverCharge>30.0</DeliverCharge>
</element>
<element>
<Number>7</Number>
<DeliverCharge>20.0</DeliverCharge>
</element>
<element>
<Number>6</Number>
<DeliverCharge>1.0</DeliverCharge>
</element>
</IndividualEntry>
</order>
</orders>
Could any one help me in fix this. Thanks in advance.
One way to do it:
orders: {
order: {
StoreID: payload.Records.storenumber,
Total: payload.Records.calculated,
(payload.Records.RecordsEntries.*RecordEntry map {
IndividualEntry: {
Number:$.entryNumber,
DeliverCharge:$.deliverycharge
}
})
}
}
Inside an object when you put an expression between parenthesis that returns an array of key-value pairs it is evaluated and used to fill the object.

Would like to convert the following flax xml file to 5-level hierarchy xml structure using xquery, so far the all the xquery code i have written did not work.
<data>
<row>
<Year>1999</Year>
<Quarter>8</Quarter>
<Month>5</Month>
<Week>10</Week>
<Flight>6/11/1995</Flight>
<Un>WN</Un>
<Air>193</Air>
</row>
<data>
Out result i would like:
<data>
<row>
<Year>
<value>1999</value>
<Quarter>
<value>8</value>
<Month>
<value>5</value>
<Week>10</Week>
<Flight>6/11/1995</Flight>
<Un>WN</Un>
<Air>193</Air>
</Month>
</Quarter>
</Year>
</row>
<data>
It's unclear what XQuery processor you're using, or the exact schema of the data you will need to process, but here is an example of how to transform the data, assuming each row contains a unique set of entries:
let $data :=
<data>
<row>
<Year>1999</Year>
<Quarter>8</Quarter>
<Month>5</Month>
<Week>10</Week>
<Flight>6/11/1995</Flight>
<Un>WN</Un>
<Air>193</Air>
</row>
</data>
for $row in $data/row
return
element row {
element Year {
element value { $row/Year/data() },
element Quarter {
element value { $row/Quarter/data() },
element Month {
element value { $row/Month/data() },
$row/Week,
$row/Flight,
$row/Un,
$row/Air
}
}
}
}
If you want a single element for each year/quarter/month, use this code:
<data>
<row>{
for $year in //row/Year/data()
return
<Year>{
<value>{ $year }</value>,
for $quarter in //row[Year=$year]/Quarter/data()
return
<Quarter>{
<value>{ $quarter }</value>,
for $row in //row[Year=$year and Quarter=$quarter]
return
<Month>{
<value>{ Month/data() }</value>,
$row/*[not(local-name(.) = ('Month', 'Quarter', 'Year'))]
}</Month>
}</Quarter>
}</Year>
}</row>
</data>
I have this XML:
<root>
<data name="lnkViewResultResource1.Text" xml:space="preserve">
<value>bekijk de resultaten</value>
</data>
<data name="lnkVoteResource1.Text" xml:space="preserve">
<value>stem</value>
</data>
<data name="number of results" xml:space="preserve">
<value>er waren reeds {0} stemmen op deze poll {1}</value>
</data>
</root>
I want to retrieve the "data" values, and for this I used:
Public Shared Function getlabels(ByVal filename As String) As Array
Dim labels = From l In XElement.Load(filename).Descendants("root").Elements("data") Select l
Return labels.ToArray
But, unfortunately, it is not working, it is not getting anything.
Any ideas?
Thanks in advance.
Alf.
You're loading the <root> XElement and asking it for descendants called root. Just get rid of the Descendants("root") call and it should be okay.
On the other hand, the query expression is pretty pointless... just use:
Return XElement.Load(filename).Elements("data").ToArray
Try
Dim labels = From l In XElement.Load(filename).Descendants("data") Select l
