pdf中文字含有内嵌字体，导致使用TextFragmentAbsorber匹配不到正确的文本，如何处理。f94a6f84-ecb5-4254-8d6a-d04e0846a377.pdf (222.1 KB)

文档中的手机号和邮箱都无法用正常的正则匹配到。

public static final String PHONE_REG = "(?:(?:1[-\\s]*[3456789][-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1}[-\\s]*\\d{1})|(?:0[1-9]\\d{1,2}[-\\s]*\\d{7,8}))(?!\\d)";
public static void main(String[] args) throws Exception {
    byte[] source = FileUtils.readFileToByteArray(new File("/Users/Carol/Desktop/f94a6f84-ecb5-4254-8d6a-d04e0846a377.pdf"));
    if (!getLicense()) {
        throw new Exception("com.aspose.pdf lic ERROR!");
    }
    try (ByteArrayInputStream searchInputStream = new ByteArrayInputStream(source); ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
        Document pdfDoc = new Document(searchInputStream);

        TextSearchOptions textSearchOptions = new TextSearchOptions(true);
        TextEditOptions textEditOptions = new TextEditOptions(0, TextEditOptions.LanguageTransformation.class);
        TextFragmentAbsorber phoneTextFragmentAbsorber = new TextFragmentAbsorber(
                PHONE_REG,
                textSearchOptions,
                textEditOptions);

        PageCollection pages = pdfDoc.getPages();
        Page page = pages.get_Item(1);
        page.accept(phoneTextFragmentAbsorber);
        logger.info("[开始搜索]");

        for (TextFragment textFragment : phoneTextFragmentAbsorber.getTextFragments()) {
            String text = textFragment.getText();
            logger.info("手机： " + text);
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
}

您能否在最后尝试以下代码示例，让我们知道您的情况如何？ 希望这对你有帮助。

Document pdfDocument = new Document(MyDir + "f94a6f84-ecb5-4254-8d6a-d04e0846a377.pdf");
 
	// Create TextAbsorber object to find all instances of the input search phrase
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("^(.+@.+|\\d{10})$"); 

// Set text search option to specify regular expression usage
TextSearchOptions textSearchOptions = new TextSearchOptions(true);
textFragmentAbsorber.setTextSearchOptions(textSearchOptions);

// Accept the absorber for first page of document
pdfDocument.getPages().accept(textFragmentAbsorber);

// Get the extracted text fragments into collection
TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();

// Loop through the fragments
for (TextFragment textFragment : (Iterable<TextFragment>) textFragmentCollection) {
    System.out.println("Text :- " + textFragment.getText());
    System.out.println("Position :- " + textFragment.getPosition());
    System.out.println("XIndent :- " + textFragment.getPosition().getXIndent());
    System.out.println("YIndent :- " + textFragment.getPosition().getYIndent());
    System.out.println("Font - Name :- " + textFragment.getTextState().getFont().getFontName());
    System.out.println("Font - IsAccessible :- " + textFragment.getTextState().getFont().isAccessible());
    System.out.println("Font - IsEmbedded - " + textFragment.getTextState().getFont().isEmbedded());
    System.out.println("Font - IsSubset :- " + textFragment.getTextState().getFont().isSubset());
    System.out.println("Font Size :- " + textFragment.getTextState().getFontSize());
    System.out.println("Foreground Color :- " + textFragment.getTextState().getForegroundColor());
}
