java生成XSLT转换文件以识别ascii字符

Question

我有一个XSLT，它将html表转换为CSV，定义如下

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                xmlns:fo="http://www.w3.org/1999/XSL/Format" >
    <xsl:output method="text" omit-xml-declaration="yes" indent="yes"/>
    <xsl:template match="/">
         <xsl:for-each select="//tr">
            <xsl:for-each select="td">
                <xsl:if test="position() > 1">,</xsl:if>
                <xsl:value-of select="."/>
            </xsl:for-each>
         <xsl:text>&#xA;</xsl:text>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

但我现在遇到的问题是，这些表的标记是用ascii码编写的

样本输入：

<table><tr>
        <th>Order ID</th>
        <th>Item ID</th>
        <th>Participant ID</th>
        <th>Status</th>
        <th>Shipping Provider</th>
        <th>Tracking Number</th>
        <th>Shipped Date</th>
        <th>Shipping Method</th></tr>
            <tr>
            <td align="center"> Choice_DJ4</td>
            <td align="center"> 4</td>
            <td align="center"> DXM09902</td>
            <td align="center"> Shipped</td> 
            <td align="center"> USPS</td> 
            <td align="center"> </td> 
            <td align="center"> 04/13/2017</td> 
            <td align="center"> Standard Ground</td> 
            </tr>
    </table>

我的问题是，有没有一种方法可以让xsl文件将ascii码识别为它们的预期字符。 更新： 这是我的java代码

String data = readFile("config/email.xml");

    System.out.println("Data: \n" + data);
    InputSource is = new InputSource(new StringReader(data));

    String configFile = "config/email-xslt.xsl";

    File stylesheet = new File(configFile);

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document document = builder.parse(is);

    StreamSource stylesource = new StreamSource(stylesheet);
    Transformer transformer = TransformerFactory.newInstance()
            .newTransformer(stylesource);
    Source source = new DOMSource(document);
    StringWriter sw = new StringWriter();
    Result outputTarget = new StreamResult(sw);

    transformer.transform(source, outputTarget);
    data = sw.toString();
    System.out.println("Output: " + data);

Answer 1

终于解决了这个问题。。。使用org.apache.commons.lang3.StringEscapeUtils.unescapeJava(str);

我的xsl文件和数据输入（config/email.xml）仍然与OP中的一样，但在传递给xsl转换器之前，我必须修改java代码以取消对这些字符的扫描

String data = readFile("config/email.xml");
data = StringEscapeUtils.unescapeXml(data);
System.out.println("Data: \n" + data);
InputSource is = new InputSource(new StringReader(data));

String configFile = "config/email-xslt.xsl";

File stylesheet = new File(configFile);

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(is);

StreamSource stylesource = new StreamSource(stylesheet);
Transformer transformer = TransformerFactory.newInstance()
     .newTransformer(stylesource);
Source source = new DOMSource(document);
StringWriter sw = new StringWriter();
Result outputTarget = new StreamResult(sw);

transformer.transform(source, outputTarget);
data = sw.toString();
System.out.println("Output: " + data);

使用XSLT3.0，可以使用^{}加载文本，^{}取消实体的scape，使用^{}解析XML字符串

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="3.0">
    <xsl:output method="text" omit-xml-declaration="yes" indent="yes"/>
    <xsl:template match="/">
        <! first, load the contents of the document (adjust path to your document)  >
        <xsl:variable name="input" select="unparsed-text('table.txt')" as="item()"/>
        <! second, unescape the angle bracket entities  >
        <xsl:variable name="table-text" select="parse-xml-fragment($input)" as="item()"/>
        <! third, parse the serialized XML string  >
        <xsl:variable name="table" select="parse-xml($table-text)" as="item()"/>
        <xsl:for-each select="$table//tr">
            <! a more simplified way of generating the CSV for each row  >
            <xsl:value-of select="td" separator=","/>
            <xsl:text>&#xA;</xsl:text>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>
