Grails - Tika内容操作

我试图解析.docx文件到xml。我可以解析它并将xml渲染为一个单独的页面。但我真正想要的只是在template,metadata中显示<body>。我怎样才能做到这一点？我尝试使用BodyContentHandler，但它摆脱了xml tags。Grails - Tika内容操作

谢谢。

我做了一个简单的代码在controller但我把事情搞糟了。这是我以前的。我从我的temp文件夹中获取文件，并将其发送给我的tikaService（我从GitHub复制的服务。）

Controller

def parse(Document documentInstance) { 
    def file = new File(documentInstance.fullPath) 
    def result = tikaService.parseFile(file) 
    render(view:"parse", text: result, contentType: "text/xml", encoding: "UTF-8") 
}

Service

class TikaService { 

    static transactional = false 

    String parseFile(File file, TikaConfig tikaConfig, Metadata metadata){ 
     SAXTransformerFactory factory = SAXTransformerFactory.newInstance() 
     TransformerHandler handler = factory.newTransformerHandler() 
     handler.transformer.setOutputProperty(OutputKeys.METHOD, "xml") 
     handler.transformer.setOutputProperty(OutputKeys.INDENT, "yes") 

     StringWriter sw = new StringWriter() 
     handler.result = new StreamResult(sw) 

     Parser parser = new AutoDetectParser(tikaConfig) 
     ParseContext pc = new ParseContext() 
     try { 
      parser.parse(new FileInputStream(file), handler, metadata, pc) 
      return sw.toString() 
     } catch (Exception e) { 
      log.error("Failed to parse file ${file.absolutePath}", e) 
      throw e 
     } 
    } 

    String parseFile(File file){ 
     TikaConfig tikaConfig = new TikaConfig() 
     Metadata tikaMeta = new Metadata() 
     return parseFile(file, tikaConfig, tikaMeta) 
    } 
}

如果我使用render我得到

当我打电话，结果从parse.gsp与${result}我得到

我希望我做的意义解释这一点。谢谢。

目前为止你有什么代码？ –

@EmmanuelRosa，我编辑了我的帖子。谢谢。 –

您可以将XML作为文本发布，以便可以复制粘贴？ –

首先，看起来像蒂卡文档给出的例子是错误的：

link to the bug ticket

这里有一个修复的问题：

link to solution

ToHTMLContentHandler toHtmlContentHandler = new ToHTMLContentHandler(outputStream, "UTF-8"); 
WriteOutContentHandler handler = new WriteOutContentHandler(toHtmlContentHandler, (int) 4000000); 
ContentHandler bodyHandler = new BodyContentHandler(handler);

希望这有助于！
