我有一个 pdf pdf 确实有 XFA 部分,因为标准 XFA 看起来像
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xdp:xdp>
<config>...</config>
<template>...</template>
<xfa:datasets>
我需要将 XML 提取到文件中;我知道文件创建方法为
StreamWriter sw;
sw = System.IO.File.CreateText("C:\\xmlread.txt");
sw.Close();
System.Windows.Forms.MessageBox.Show("file created successfully");
但是,将 xml 部分放入此文件尚不清楚,我看到 XML 可以从 PDF 派生为
FileOutputStream os = new FileOutputStream(dest);
PdfReader reader = new PdfReader(src);
XfaForm xfa = new XfaForm(reader);
Document doc = xfa.getDomDocument();
Transformer tf = TransformerFactory.newInstance().newTransformer();
tf.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
tf.setOutputProperty(OutputKeys.INDENT, "yes");
tf.transform(new DOMSource(doc), new StreamResult(os));
reader.close();
代替这个我用
file = new org.pdfclown.files.File(fileName);
org.pdfclown.documents.Document document = file.Document;
org.pdfclown.documents.interaction.forms.Form form = document.Form;
表单部分指定 Acrobat 字典是否存在的表单类型;请帮我在记事本中提取xml文件
