我正在尝试使用XML数据源生成报告。我的输入xml文件有 4 行。但是JR引擎生成的报告只包含第一行。
我有<detail> <band> ... </band> </detail>
部分来获取数据
我的jrxml文件看起来像这样
<?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">

我的输入 xmls 是
<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>
我的 Java 客户端是
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));
如何从输入xml中获取所有值?
另外如何获取 id 值?对于第一个 xml 行<field count="7556">one</field>
<fieldDescription><![CDATA[//field[@count]]]></fieldDescription>
<fieldDescription><![CDATA[//field]]></fieldDescription>
给出与“一”相同的数据
