I would like to have an index for the ID attribute. My configuration file is:
<collection xmlns="http://exist-db.org/collection-config/1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<index>
<create qname="#ID" type="xs:string"/>
</index>
<triggers>
<trigger class="org.exist.extensions.exquery.restxq.impl.RestXqTrigger"/>
</triggers>
The index I have created is only used in pure xpath queries, such as
//Order[#ID ="170475"]
but not in xquery queries such as:
for $ord in//Order/#ID
where $ord = "150985"
return $ord
Is there any way to fix this?
Please try to change your query into
for $ord in//Order
where $ord/#ID = "150985"
return $ord
The query engine tries to rewrite your expression in order to use the index. It will fail analyzing your previous formulation, but should succeed on the one above.
The general recommendation is to use XPath statements with filters where possible, because they are easier to rewrite automatically.
It is documented that the eXist-db xquery processor has difficulties to optimize queries with the where clause.
Although your second query is syntactically correct, it is recommended to use the XPATH equivalent.

I wanted to extract the attributes form an xml using Pig Latin.
This is a sample of the xml file
<CATALOG>
<BOOK>
<TITLE test="test1">Hadoop Defnitive Guide</TITLE>
<AUTHOR>Tom White</AUTHOR>
<COUNTRY>US</COUNTRY>
<COMPANY>CLOUDERA</COMPANY>
<PRICE>24.90</PRICE>
<YEAR>2012</YEAR>
</BOOK>
</CATALOG>
I used this script but it didn't work:
REGISTER ./piggybank.jar
DEFINE XPath org.apache.pig.piggybank.evaluation.xml.XPath();
A = LOAD './books.xml' using org.apache.pig.piggybank.storage.XMLLoader('BOOK') as (x:chararray);
B = FOREACH A GENERATE XPath(x, 'BOOK/TITLE/#test'), XPath(x, 'BOOK/PRICE');
dump B;
The output was:
(,24.90)
I hope someone can help me with this.
Thanks.
There are 2 bugs in piggybank's XPath class:
The ignoreNamespace logic breaks searching for XML attributes
https://issues.apache.org/jira/browse/PIG-4751
The ignoreNamepace parameter is defaulted to true and cannot be overwritten
https://issues.apache.org/jira/browse/PIG-4752
Here is my workaround using XPathAll:
XPathAll(x, 'BOOK/TITLE/#test', true, false).$0 as (test:chararray)
Also if you still need to ignore namespaces:
XPathAll(x, '//*[local-name()=\'BOOK\']//*[local-name()=\'TITLE\']/#test', true, false).$0 as (test:chararray)
How do i find a text() node in XmlConfig and use it to remove the parent nodeset. All the examples I have seen just find and remove the 'found' node not the parent nodes.
My understanding is that this Xpath finds the matching node via verify path and ElementPath is the path of the nodes to remove. However Its not working at all.
Is text() supported?, I have tried [[*='ATrigger'[]], [[].='ATrigger'[]] but still no luck.
<util:XmlConfig Id="RemoveATriggerCompletely" File="[#QuartzXmlJob]" Sequence="104" Action="delete" On ="install" Node="element"
ElementPath="//job-scheduling-data/schedule/"
VerifyPath="//job-scheduling-data/schedule/trigger/cron/name[\[]text()='ATrigger'[\]]"/>
Given the following XML
<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
<schedule>
<trigger>

<group>default</group>
<description>Every 2 minutes</description>
<job-name>ATriggerJob</job-name>
<job-group>defaultGroup</job-group>
<misfire-instruction>SmartPolicy</misfire-instruction>
<!-- every 5mins -->
<cron-expression>2 * * * * ?</cron-expression>
</cron>
</trigger>
<trigger>
<cron>

<description>Every 2 minutes</description>

<misfire-instruction>SmartPolicy</misfire-instruction>
<!-- every 5mins -->
<cron-expression>2 * * * * ?</cron-expression>
</cron>
</trigger>
The output i require is
<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
<schedule>

I have been banging my head against a wall for hours now so any help whatsoever is very much appreciated.
I'm not familiar with that "XmlConfig" task.
But I see two issues.
You need to alias the namespace and use that alias for the xpath "select".
I show the XmlPeek version below. Note I use "peanut", you can use any alias name you want.
Note the query now has "peanut:" in all the element names.
<!-- you do not need a namespace for this example, but I left it in for future reference -->
<XmlPeek Namespaces="<Namespace Prefix='peanut' Uri='http://quartznet.sourceforge.net/JobSchedulingData'/>"
XmlInputPath=".\Parameters.xml"
Query="//peanut:job-scheduling-data/peanut:schedule/peanut:trigger/peanut:cron/peanut:name[text()='ATrigger']/../..">
<Output TaskParameter="Result" ItemName="Peeked" />
</XmlPeek>
Note my "../.."
Once you find the correct element, finding its parent(s) is simple as the ".." notation.
You'll need to figure out how to add the namespace and alias to your Task (XmlConfig)
APPEND:
http://sourceforge.net/p/wix/bugs/2384/
Hmmm...dealing with a namespace isn't trivial. I think you're having a similar issue to what is reported there.
APPEND:
"Inline" Namespacing ... (Yuck)
<XmlPeek
XmlInputPath=".\Parameters.xml"
Query="//*[local-name()='job-scheduling-data' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='schedule' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='trigger' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='cron' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='name' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData'][text()='ATrigger']/../..">
<Output TaskParameter="Result" ItemName="Peeked" />
</XmlPeek>
Aka, try this Xpath:
"//*[local-name()='job-scheduling-data' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='schedule' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='trigger' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='cron' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData']/*[local-name()='name' and namespace-uri()='http://quartznet.sourceforge.net/JobSchedulingData'][text()='ATrigger']/../.."

I would like to have all hpKeycode using local-name() in the XPath expression. I tried
//*[local-name()='hpKeycode']
but this gives me only the first node which is 189161. This
/*[local-name()='hpKeycode'][2]
also does not work. Any help would be greatly appreciated.
You can try with XQuery. In the property transfer step select Use XQuery checkbox as you see in the image below. And use this code:
declare namespace soap='http://schemas.xmlsoap.org/soap/envelope/';
declare namespace ns1='http://ws.example.com/roma/201907';
<ns1:offer>
{
for $id in //*[local-name()='hpKeycode'] return string($id)
}
</ns1:offer>
EDIT:
If you want to avoid the use of XQuery, you can add three Transfers on your property transfer, on each one use:
First id
(//*[local-name()='hpKeycode'])[1]
Second id
(//*[local-name()='hpKeycode'])[2]
Third id
(//*[local-name()='hpKeycode'])[3]
Hope this helps,
This would not work in the way you expect it to because you are pulling a single set of values. You would need to specify what node branch you want further up the tree.
Its like road ways... if you were giving someone directions you would need to inform them which way to go for each fork in the road. Lets say you wanted to tell them how to get to one of 3 possible airports each located in a different city. If you said "as you arrive at airports 1,2, and 3 enter the 2nd". They would be baffled and say something like "what city though?" and maybe "its not possible for them to exist in the same location".
Solution:
Here is what you would want given the xml you provided (both work in soapui).
Xpath 2.0
//*:offer[4]/*:hData/*:hpKeycode
//*:offer[5]/*:hData/*:hpKeycode
//*:offer[6]/*:hData/*:hpKeycode
Xpath 1.0
//*[local-name()='offer'][4]/*[local-name()='hData']/*[local-name()='hpKeycode']
//*[local-name()='offer'][5]/*[local-name()='hData']/*[local-name()='hpKeycode']
//*[local-name()='offer'][6]/*[local-name()='hData']/*[local-name()='hpKeycode']
Hope this more detailed explanation helps!
I have an xml like this:
<order>
<orderheader>
<orderissuedate>1/11/2013</orderissuedate>
</orderheader>
</order>
in the mule logger component set with INFO, i have a mule expression that tries to print out the orderissuedate 1/11/2013.
i use the expression:
[xpath('/order/orderheader//orderissuedate')] which didn't work.
i also tried: #[xpath('/order/orderheader/orderissuedate/text()').text] that didnt work also.
can someone tell me what the correct xpath expression is. i get this error message:
java.lang.RuntimeException: org.mule.api.MuleRuntimeException: Failed to evaluate XPath expression: "/Order/OrderHeader/OrderIssueDate/text()"
I've tested these xpath expressions using online xpath checkers, and they seem to work. thanks for your help.
Here is the original xml:
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE Order>
<Order
xmlns:core="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<OrderHeader>
<OrderNumber>
<BuyerOrderNumber>111111</BuyerOrderNumber>
</OrderNumber>
<OrderIssueDate>2013-06-28T08:40:12</OrderIssueDate>
<OrderReferences>
<AccountCode>
<core:RefNum></core:RefNum>
</AccountCode>
</OrderReferences>
</OrderHeader>
</Order>
and the error output from mule:

Use this:
<logger message="OrderIssueDate is #[xpath('//Order/OrderHeader/OrderIssueDate').text]" level="INFO" />
Make sure that to use the case correctly for your XML elements hierarchy. You have order in top XML while Order in lower one and so on
the xpath expression that would work according to me is #[xpath://orderissuedate] To print using the logger you should use something like <logger message="#[xpath://orderissuedate]" level="INFO"/>
From the conversation on one of the answers the following solutions hould work.
<logger message="Value of Order Issue Date #[xpath('//OrderIssueDate').text]" level="INFO" />
It would be better if the DTD of the Order is also provided.
Your original XML seems to have namespace :-
xmlns:core="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd"

So, if you need to extract the value using Xpath from your original XML, you need Mule namespace manger :- https://developer.mulesoft.com/docs/display/current/XML+Namespaces
Other than that if you want to extract the value from your XML you shown above, you can use the Mules latest Xpath3 available right now from Mule version 3.6 which is easy to use :- https://developer.mulesoft.com/docs/display/current/XPath
Hope it helps you :)
You can use the mule latest xpath3 like this if you are getting namespaces
[xpath3('//*:orderissuedate/text()')]
Try this, it may help:
#[xpath3('//order/orderheader/orderissuedate/text()')]
I have what should be a fairly simple requirement.
I want to use LINQ to XML in a VS2010 project to get the following node values:
GPO->Name
GPO->LinksTo->SOMName
GPO->LinksTo->SOMPath
Then:
If GPO->User->ExtensionDataCount node exists, I want to return count of all child nodes
Likewise:
If GPO->Computer->ExtensionData exists, return count of all child nodes
here is the XML, those of you familiar with Group Policy exports will have seen this before:
<?xml version="1.0" encoding="utf-16"?>
<GPO xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.microsoft.com/GroupPolicy/Settings">
<Identifier>
<Domain xmlns="http://www.microsoft.com/GroupPolicy/Types">our.domain.fqdn</Domain>
</Identifier>
<Name>The Name I want to get</Name>
<Computer>
<VersionDirectory>1</VersionDirectory>
<VersionSysvol>1</VersionSysvol>
<Enabled>true</Enabled>
</Computer>
<User>
<VersionDirectory>4</VersionDirectory>
<VersionSysvol>4</VersionSysvol>
<Enabled>true</Enabled>
<ExtensionData>
<Extension xmlns:q1="http://www.microsoft.com/GroupPolicy/Settings/Scripts" xsi:type="q1:Scripts">
<q1:Script>
<q1:Command>Logon.cmd</q1:Command>
<q1:Type>Logon</q1:Type>
<q1:Order>0</q1:Order>
<q1:RunOrder>PSNotConfigured</q1:RunOrder>
</q1:Script>
</Extension>
<Name>Scripts</Name>
</ExtensionData>
</User>
<LinksTo>
<SOMName>an interesting data value</SOMName>
<SOMPath>some data value</SOMPath>
<Enabled>true</Enabled>
<NoOverride>false</NoOverride>
</LinksTo>
</GPO>
I have loaded the XML file into an XDocument, then tried to pull the Name value with:
XDoc.Elements("Name").FirstOrDefault.Value
XDoc.Descendants("Name").First().Value
But I'm getting errors: Object reference not set to an instance of an object and then: Sequence contains no elements.
I'm guessing I might have the path wrong, but I thought Descendants didn't require an exact path..
Where am I going wrong?
You have to use the declared namespace:
XNamespace ns = "http://www.microsoft.com/GroupPolicy/Settings";
var firstName = xdoc.Descendants(ns + "Name").First().Value;
