I am trying to generate a report from XML file using xml data source. However generated report has only one row. Whereas input file has 4 values.
My jrxml file is
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd"> <jasperReport name="simpleReport"> <queryString language="xPath"><![CDATA[/response/results]]></queryString> <field name="field" class="java.lang.String"> <fieldDescription><![CDATA[//field]]></fieldDescription> </field> <field name="count" class="java.lang.String"> <fieldDescription><![CDATA[//field[@count]/@count]]></fieldDescription> </field> <title> <band height="50"> <staticText> <reportElement x="0" y="0" width="180" height="15"/> <textElement/> <text><![CDATA[Report]]></text> </staticText> </band> </title> <pageHeader> <band/> </pageHeader> <columnHeader> <band height="20"> <staticText> <reportElement x="180" y="0" width="180" height="20"/> <textElement> <font isUnderline="true"/> </textElement> <text><![CDATA[Event Name]]></text> </staticText> <staticText> <reportElement x="360" y="0" width="180" height="20"/> <textElement> <font isUnderline="true"/> </textElement> <text><![CDATA[Count]]></text> </staticText> </band> </columnHeader> <detail> <band height="20"> <textField> <reportElement x="180" y="0" width="180" height="15"/> <textElement/> <textFieldExpression><![CDATA[$F{field}]]></textFieldExpression> </textField> <textField> <reportElement x="360" y="0" width="180" height="15"/> <textElement/> <textFieldExpression><![CDATA[$F{count}]]></textFieldExpression> </textField> </band> </detail> <columnFooter> <band/> </columnFooter> <pageFooter> <band height="15"> <staticText> <reportElement x="0" y="0" width="40" height="15"/> <textElement/> <text><![CDATA[Page:]]></text> </staticText> <textField> <reportElement x="40" y="0" width="100" height="15"/> <textElement/> <textFieldExpression class="java.lang.Integer"><![CDATA[$V{PAGE_NUMBER}]]></textFieldExpression> </textField> </band> </pageFooter> <summary> <band/> </summary> </jasperReport>
input xml file is
<response id="1074200577"> <results id1="0" id2="0"> <field count="7556">one</field> <field count="7524">two</field> <field count="7402">three</field> <field count="7304">four</field> </results> </response>
My Java code looks like below
JasperCompileManager.compileReportToFile(inpuutjrxml, outputjasper); JRXmlDataSource source = new JRXmlDataSource(new File(sourceFile)); HashMap<String, Object> params = new HashMap<String, Object>(); JasperPrint jasperPrint = JasperFillManager.fillReport(outputjasper, params, source); JasperExportManager.exportReportToPdfStream(jasperPrint, new FileOutputStream(pefoutput));
Is it a xpath issue or some modification needs to be done for jrxml file when we use xml data source?

Passing the xml path while creating the data source fixed the issue.
Used following constructor to create a new xml data source
JRXmlDataSource source = new JRXmlDataSource(new File(file,"/response/results/field");
Then removed query String from jrxml. Modified field section looks like below
<field name="field" class="java.lang.String"> <fieldDescription><![CDATA[child::text()]]></fieldDescription> </field> <field name="count" class="java.lang.String"> <fieldDescription><![CDATA[@count]]></fieldDescription> </field>

As I test with my own xml with the same format as yours, it works fine. I think it may from your xml file, but I not sure.
This is my xml file:
<?xml version="1.0" encoding="utf-8"?> <customers d="00001"> <customer type1="A" type2="A"> <person id="1">A</person> <person id="2">B</person> <person id="3">C</person> <person id="4">D</person> </customer> </customers>
This is my report code:
<?xml version="1.0" encoding="UTF-8"?> <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="dataxml" language="groovy" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="ef5c8faf-8453-4ad5-8e1e-0eb8441c05bf"> <property name="ireport.zoom" value="0.8264462809917354"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <queryString language="xPath"> <![CDATA[/customers/customer/person]]> </queryString> <field name="id" class="java.lang.String"> <fieldDescription><![CDATA[@id]]></fieldDescription> </field> <field name="person" class="java.lang.String"> <fieldDescription><![CDATA[child::text()]]></fieldDescription> </field> <background> <band splitType="Stretch"/> </background> <columnHeader> <band height="24"> <staticText> <reportElement uuid="2e20d0c1-2c6e-45fd-a655-beccf4e665a4" x="0" y="0" width="277" height="20"/> <textElement/> <text><![CDATA[child::text()]]></text> </staticText> <staticText> <reportElement uuid="c9cde1b4-929b-4ab7-92ae-0c4f6b711d20" x="277" y="0" width="277" height="20"/> <textElement/> <text><![CDATA[@id]]></text> </staticText> </band> </columnHeader> <detail> <band height="39" splitType="Stretch"> <textField> <reportElement uuid="b45481e9-c7bd-4189-bba8-893a64a976cd" x="0" y="0" width="277" height="20"/> <textElement/> <textFieldExpression><![CDATA[$F{person}]]></textFieldExpression> </textField> <textField> <reportElement uuid="52e2bfe1-616b-4da7-bdeb-4bc33d959c1d" x="277" y="0" width="277" height="20"/> <textElement/> <textFieldExpression><![CDATA[$F{id}]]></textFieldExpression> </textField> </band> </detail> <summary> <band height="42" splitType="Stretch"/> </summary> </jasperReport>
