将ArrayList渲染为XSLT

Question

我有一个对象PDFData与一些属性。其中一个是Arraylist，一个是String，另一个是自定义对象(带有一些基本属性)。

我需要用XSLT呈现这两个列表，以便用Apache-FOP创建PDF文件。我用谷歌搜索了很多方法来解决这个问题，但我什么也没找到。

渲染PDF的类是:

public class PDFRender {
public static final String SUMMARY_REPORT_XSL = "summary_report.xsl";
//private final Logger log = LoggerFactory.getLogger(getClass());
public ByteArrayInputStream createPDFFile(ByteArrayOutputStream xmlSource) throws IOException {
    ByteArrayInputStream inputStream = null;
    InputStream template = Thread.currentThread().getContextClassLoader().getResourceAsStream(SUMMARY_REPORT_XSL);
    StreamSource transformSource = new StreamSource(template);
    FopFactory fopFactory = FopFactory.newInstance();
    FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
    ByteArrayOutputStream pdfOutStream = new ByteArrayOutputStream();
    StreamSource source = new StreamSource(new ByteArrayInputStream(xmlSource.toByteArray()));
    Transformer xslfoTransformer;
    try {
        TransformerFactory transfact = TransformerFactory.newInstance();
        xslfoTransformer = transfact.newTransformer(transformSource);
        Fop fop;
        try {
            fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, pdfOutStream);
            // Resulting SAX events (the generated FO) must be piped through to FOP
            Result res = new SAXResult(fop.getDefaultHandler());
            // Start XSLT transformation and FOP processing
            try {
                xslfoTransformer.transform(source, res);
                inputStream = new ByteArrayInputStream(pdfOutStream.toByteArray());
            } catch (TransformerException e) {
                String msg = "Caught exception transforming source to generate PDF";
                //log.error(msg, e);
                throw new RuntimeException(msg, e);
            }
        } catch (FOPException e) {
            String msg = "Caught FOP exception generating PDF";
            //log.error(msg, e);
            throw new RuntimeException(msg, e);
        }
    } catch (TransformerConfigurationException e) {
        String msg = "Caught exception transforming source to generate PDF";
        //log.error(msg, e);
        throw new RuntimeException(msg, e);
    }
    return inputStream;
}
public ByteArrayOutputStream getXMLSource(PDFData data) throws Exception {
    JAXBContext context;
    ByteArrayOutputStream outStream = new ByteArrayOutputStream();
    try {
        context = JAXBContext.newInstance(PDFData.class);
        Marshaller m = context.createMarshaller();
        m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
        m.marshal(data, outStream);
    } catch (JAXBException e) {
        String msg = "Caught exception marshalling application to generate PDF";
        //log.error(msg, e);
        throw new RuntimeException(msg, e);
    }
    return outStream;
}
}

PDFData如下:

@XmlRootElement(name = "PDFData")
public class PDFData {
public String clientName;
public String clientProfile;
public String clientLang;
public URL clientLogo;
public ObjectId verificationId;
public String verificationCountry;
public String verificationDocumentType;
public List<Page> verificationPages = new ArrayList<>();
public String verificationTemplateName;
public Long verificationTime;
public List<ActionResult> verificationActions = new ArrayList<>();
public List<String> verificationMrz = new ArrayList<>();
/* ... */
}

我的XSLT没有相关性，因为我还没有任何关于它的东西。也许只是为了评论它，是相关的，当我必须访问一些属性(例如clientName)，我这样做:

<xsl:when test="clientName = 'Test client'">Orange</xsl:when>

我使用XSLT 1.1与Jar依赖'org.apache.xmlgraphics:fop:1.0'(版本1.1。gradle不能加载依赖项，我不知道为什么)。

摘要:有人知道如何将Java列表呈现为XSL模板吗?

提前感谢!

UPDATE 1:我找到了一个解决办法。它解决了我的一个问题。我可以得到所有的值。但现在我有另一个问题。我怎样才能在它们之间循环?

UPDATE 2: @KevinBrown认为我的XSLT可能很重要，所以这里是我的XSLT:

UPDATE 3: Woohooo!!这个周末我尝试了一些解决方案，我得到了一个循环:

<xsl:for-each select="verificationMrz">
    <xsl:variable name="i" select="position()" />
    <xsl:value-of select="$i" />
</xsl:for-each>

好的,太酷了!但是，当我试图访问列表与索引(<xsl:value-of select="verificationMrz[$i]" />)，我没有得到任何值。我已经检查了<xsl:value-of select="verificationMrz[1]" />列表是否为空，它工作得很好。所以我认为我的问题是变量i，也许数据类型?我不知道…

Answer 1

解决!这是我一直在寻找的解决方案:

<xsl:for-each select="verificationMrz">
    <xsl:value-of select="current()" />
</xsl:for-each>

这将打印我的字符串列表。对于打印我的对象，我还不确定如何检索它，但我会尽快发布它我解决它。
