XSL 文件中的 Java setParameter

Question

我在从正在 XLS 文件中添加参数的 Java 项目打印 PDF 文件时遇到问题。该项目读取 XML 文件，然后从 XSL 样式表生成 PDF 文件。文件内容见下文。
正如您在XLS文件中看到的，我想在“studentNumber”处指定，但问题是指定的“studentNumber”需要在Java项目中设置。我尝试了很多事情并在互联网上搜索，但我找不到答案。任何想法我都需要改变以使这个项目正确。

XML 文件:

<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="studentResultXLS.xsl"?>
<cursus>
    <enroll>
        <studentnumber>s484766</studentnumber>
        <cursuscode>ISDTCEX.B627</cursuscode>
        <enrolldate dateformat="eejjmmdd">20111121</enrolldate>
        <acquire>ja</acquire>
        <grade>4</grade>
        <result></result>
    </enroll>
    <enroll>
        <studentnumber>s484766</studentnumber>
        <cursuscode>ISDTSIP.T470</cursuscode>
        <enrolldate dateformat="eejjmmdd">20111116</enrolldate>
        <acquire>ja</acquire><grade>2</grade>
        <result></result>
    </enroll>
    <enroll>
        <studentnumber>s484767</studentnumber>
        <cursuscode>ISDTSIP.T470</cursuscode>
        <enrolldate dateformat="eejjmmdd">20111116</enrolldate>
        <acquire>ja</acquire><grade>2</grade>
        <result></result>
    </enroll>

</cursus>

XLS 文件:

<xsl:param name="studentnumber"/>.....

<fo:table-body>
    <xsl:for-each select="/cursus/enroll[studentnumber='s484766']">
        <fo:table-row>

            <fo:table-cell>
                <fo:block> <xsl:value-of select="studentnumber"/> </fo:block>
            </fo:table-cell>

                <fo:table-cell>
                    <fo:block> <xsl:value-of select="cursuscode"/> </fo:block>
                </fo:table-cell>
            </fo:table-row>
    </xsl:for-each>
    </fo:table-body>

Java代码:

 transformer.setParameter("studentnumber", "s484766");

Answer 1

要读取参数值，您需要在其前面加上 $ 符号:

<xsl:value-of select="$studentnumber"/>
