I am using postgresql as database. In db i have one column which contains xml with language codes. I want to parse that xml and get value trough the report language.
select o.name,o.price from bookdefinations o This o.name contains that xml value:
<?xml version="1.0" encoding="UTF-8"?>
<values>
<en-us>en value</en-us>
<es>es value</es>
<ru>ru value</ru>
<tr>tr value</tr>
</values>
Can i parse this with jasper's expressions or can i parse while selecting from db (i dont have any idea how to get report language in select query and parse xml in select)
There is a xmldatasource for jasperreport, you can do a subreport and send the blob to that subreport as an xmldatasource, then you can parse the xml in the subreport and show the content, I'm not sure if you want to show the values or the entire xml, if it is a report I guess you should show the values in a pretty way I mean not as xml, check this link
http://jasperreports.sourceforge.net/sample.reference/xmldatasource/
You could do this directly in postgresql during the select.
PostgreSql has an XML Type and various XML functions.
If you take a look at those functions, you'll see the xpath function which can be used to extract data from XML types during a select statement.
For a reference to xPath, take a look at the tutorial from W3Schools.

i have a XML file in : /res/xml/countries.xml
and also i have a view with editText inside.
i want to search that text (users should type in editText) in my countries.xml file!
here is my xml file :
<?xml version="1.0" encoding="utf-8"?>
<countries>
<country>
<name>United State</name>
</country>
<countries>
If you want to read a whole document, use XML Parser, like Pull already mentioned. If you only want to pick out only one or few certain things, I would suggest XPath. Here is a good Tutorial on how to use XPath in Java.
First you need to parse that xml file containing the countries name. Store list of countries in any arraylist and then write any search algo to search the text found from that edittext.
Try this xpath tutorial...
You will have good learning experience...
This tutorial explain clearly how to parse an XML file : XML parser
Other tutorial simpler with XPath : Xparse tutorial
Scenario:
I am trying to unmarshall the Acord XML(Insurance standard XML) to Java-Acordform and then trying to map the Acordform object to a one more formbean-Policformbean in order to display the values in the JSP where user can edit the values.Again I have to marshall the Java object values to XML.There is an XSD available for this Acpord XML.Suing XMLSpy I have created XSD from XML.Using XJC I have created the java objects from XSD.
Since Acord being a complex XML and the structure of the generated Java object is not straight forward I have created Policformbean.Using Policformbean , I am tring to display the values in the JSP.
Issue:
I am facing few issues while setting the acordform to Policformbean.May I know if using JAXB is the best approach for me to display the XML element values when Acord XML is used?
If anyone has worked on JAXB conversion from Acord XML to Java object values, please guide me.
Thanks in Advance.
I have some XML data inside an XML file which i want to pass to another application. I have used XMLPullPaser.
<?xml version="1.0" encoding="utf-8" ?>
<node1>
<node2>dd03</node2>
<node3>,17,0,,**<xml><cell>555</cell></xml>**,</node3>
</bintextobj>
node 3 contains the data as highlighted. The xml I want to pass as data of xml file. Is there any way of achieving this?
Use CDATA to store the value. This will cause the parser to treat the value of node3 like plain text.
<node3><![CDATA[,17,0,,**<xml><cell>555</cell></xml>**,]]></node3>
write xsl to extract the <xml>..</xml> and write into the new xml file which can be passed to the other applications.
i would like to load an image to get the metadata. my code is like this :
the value of "url" is like this : "http:\localhost:8080\mypics\pic1.jpg"
<xsl:call-template name="mypic">
<xsl:with-param name="metadata" select="document($url)/metadata"/>
</xsl:call-template>
i get this exception : ID systÞme inconnu; Ligne #47; Colonne #38; Unable to load the requested document : C:\http:\localhost:8080\mypics\pic1.jpg (the specific path was not found)
Thanks for help.
The value of $url should be
http://localhost:8080/mypics/pic1.jpg
Update
According to this documentation you need to specify an URI and the resource at that URI has to be of xml type. I strongly doubt, that you can handle images with this expression. The document() function is used to access (xml-)nodes in external documents.
I guess, the backslashes made the processor believe the string was pointing to a file resource, relative to C:\.

In XSLT you cant load a file unless it contains a well-formed XML document, or just text (not binary).
In an XSLT transformation only XML documents (with the document() function) or text files (with the XSLT 2.0 unparsed-text()) function can be loaded.
I assume that there is no native XSLT way to do this as I guess Dimitrie would have shown us one if existed.
The alternative is to drop out to Java. Write your own extension function in Java and call it from your XSLT. This link shows how this can be done:

I have this job in Talend that is supposed to retrieve a field and loop through it.
My big problem is that the code is looping through the XML fields but it's returning null.
Here is a sample of the XML:
<?xml version="1.0" encoding="ISO-8859-1"?>
<empresas>
<empresa>
<imoveis>
<imovel>
[-- some fields -- ]
<fotos>
<nome id="" order="">photo1</nome>
<nome id="" order=""></nome>
<nome id="" order=""></nome>
<nome id="" order=""></nome>
</fotos>
</imovel>
[ -- other entries here -- ]
</imoveis>
</empresa>
</empresas>
Now using the tExtractXMLField component I am trying to get the "fotos" element.
Here is what I have in the component:
I have tried to change the XPath query and the XPath loop query but the result is either I don't loop through the field or I get the null in the value field in the tMap.
Here is an image of the job:
You can see that I have retrieved 4 items from the XML but what I get is null in the "nome" field. There must be something wrong with the XPath but I can't seem to find the problem :(
Hope someone can help me out. Thanks
Notes: I am using talendv4.1.2 on ubuntu 10.10 64bit
If you want to loop on <nome> nodes your Loop XPath Query has to be
"/empresas/empresa/imoveis/imovel/fotos/nome"
and foto_nome XPath Query something like
"text()"
Take care: I also corrected an error in your XML that could bring issues (</imoveis> missing the "s").
There are two ways to go about it. One way is to use directly XMLinput and the instructions that bluish mentioned.
The other way is to continue on the path that you chose. In the XMLinput, make sure that your Loop XPath query is set to "/empresas/empresa/imoveis/imovel/fotos" and that you pass through the fotos element with the Get Nodes option checked. The XPath Query of your fotos element should be "../fotos" or ".".
Your extractXMLField component looks to be well configured.
Also, I don't know what tSetGlobalVar does in your design, but make sure it doesn't affect the fotos element that you're trying to pass through.
I have made a test job, this will help you definitely. If I'm not wrong you want to get all the "nome" under the "fotos" tag.
Try to change your loop xpath to the top level in the file, "empresas". Sometimes that works for me, also I have seem the "?xml version="1.0" encoding="ISO-8859-1"?" tag cause problems before, you could try to remove that.
Also make sure that the encoding is set correctly in the tFileInputXML.
I think you are confusing reading XML and extracting XML from XML.
Reading XML:
If the part of XML you have provided is the file readed by you tFileInputXML you don't need tExtractXMLField, just configure the tFileInputXML as this:
set the xpath loop to the <nome> elements, like this "//nome"
add 3 columns in the tFileInputXML component id, order and content
get content column with xpath query "."
get id value with xpath query "#id"
get order value with xpath query "#order"
Extracting XML from XML:
That is the goal of the tExtractXMLField component:
It allows to parse XML data contained in a database column or another XML document as if it was itself a data flow.
To put it in a nutshell, tExtractXMLField create a flow of data from a column record containing XML.
It is very useful when parsing soap query result: server reply is usually provided as xml, like this one:
<arg2>
<![CDATA[
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<exportInscriptionEnLigneType>
<date>2015-04-10</date>
<nbDossiers>2</nbDossiers>
<reference>20150410100</reference>

<dossier>
<numOrdre>2</numOrdre>
<identifiantDossier>BBBBB</identifiantDossier>
</dossier>
</listeDossiers>
</exportInscriptionEnLigneType>
]]>
</arg2>
In XML above, arg2>element contains an XML document that you may need to parse.
tExtractXMLField has been created for this purpose.
I've written a tutorial on how to achieve this work, please have a look here "how to extract xml from xml". It is in french but screenshots may help understanding the few comments provided.
Hope it will help.
