【问题描述】:
我在使用 XSLFO 和 XSLT 从 Java 对象生成 PDF 时遇到问题:
我有这个代码:
TransformerFactory.newInstance("org.apache.xalan.processor.TransformerFactoryImpl",
Thread.currentThread().getContextClassLoader());
templates = factory.newTemplates(new StreamSource(PdfGenerator.class.getResourceAsStream(ORDERS_XSL)));
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
Source src = getSourceForCommandList(commandeList);
try {
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
Result res = new SAXResult(fop.getDefaultHandler());
templates.newTransformer().transform(src, res);
} finally {
out.flush();
}
我的 xslt 使用 fo 命名空间:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:template match="orders">
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master master-name="simpleA4"
page-height="29.7cm" page-width="21cm" margin-top="2cm"
margin-bottom="1cm" margin-left="0.5cm" margin-right="0.5cm">
<fo:region-body />
</fo:simple-page-master>
</fo:layout-master-set>
<xsl:apply-templates select="order" />
</fo:root>
</xsl:template>
...
</xsl:template>
</xsl:stylesheet>
它工作正常,并使用 Apache FOP 和 XSLT 从源对象生成 PDF。
但是,当我添加此行以尊重有关安全性的最佳做法时:
factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
因为没有加载 fo 命名空间,所以它中断了,我在模板解析时收到了这些警告:
SystemId Unknown; Line #13; Column #67; "master-name" attribute is not allowed on the fo:simple-page-master element!
SystemId Unknown; Line #13; Column #67; "page-height" attribute is not allowed on the fo:simple-page-master element!
SystemId Unknown; Line #13; Column #67; "page-width" attribute is not allowed on the fo:simple-page-master element!
SystemId Unknown; Line #13; Column #67; "margin-top" attribute is not allowed on the fo:simple-page-master element!
【问题讨论】:
-
只是一个建议,是否可以在 SAXResult 中设置名称空间、
formating object的前缀。我想你操纵了所述对象的属性......祝你好运:-)
