XSL-FO 文档：在具体的 fo:table 行中插入 break-before="page" 属性

Question

我有一份 XSL-FO 文件。该文档有很多 fo:table 嵌套。有一个内部 fo:table 有 9 列和很多行，在这个例子中，第一行是 table header 和其他行，从 1 到 20 的内容。在下面的示例中，您可以看到作为注释，对于每个 FOPTable (fo:table)，它都指示了一个唯一标识符，但对于相同的 table，此标识符并不总是相同的。它由创建此 XSL-FO 文档的应用程序随机生成。

我的问题是：我想找到 table 的第一列 header 值设置为 HEADER_COL1（此值始终相同），在本例中， table 用 id:997 标识（请记住，我无法根据此标识符搜索 table，因为每次应用程序创建 XSL-FO 文档时它都会随机更改）。找到所需的 table 后，我想要以下内容：

如何为混凝土插入属性 break-before="page" fo:table-行项目？
我想获取此内部 table 的行数。

例如：

例如，如果我想为第 15 fo:table 行项目插入此属性，我该怎么做？我想要一个参数化的通用方法，该方法将一个数字作为参数，该数字指示放置此属性的 fo:table 行。

我知道我可以使用以下方法阅读 XSL-FO 文档：

string xmlFile = File.ReadAllText(@"C:\Temp\MyXSLFO.xml");
XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml(xmlFile);

但是一旦加载我就不知道该怎么做了。

注意：我正在使用 Visual Studio 2008、C# 和 .NET 3.5。

获取您的数据并删除所有单元格和其他不重要的内容，可以简单地将身份 XSL 应用于 XSL FO 并仅修改目标行。

从这个开始 XML:

                            <fo:table-row/>                            
                            <fo:table-row/>                            
                            <fo:table-row/>                            
                            <fo:table-row/>                            
                        </fo:table-body>
                    </fo:table>
                </fo:table>

            </fo:table>

        </fo:flow>
    </fo:page-sequence>
</fo:root>

并应用此 XSL，它按原样输出所有内容，除了在目标的第 12 行插入分页符的模板 table:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:fo="http://www.w3.org/1999/XSL/Format"
    version="2.0">
    <xsl:param name="breakrow" select="12"/>

    <xsl:template match="fo:table-row">
        <xsl:variable name="rowcnt" select="count(preceding-sibling::fo:table-row)"/>
        <xsl:choose>
            <xsl:when test="parent::fo:table-header">
                <fo:table-row>
                    <xsl:apply-templates/>
                </fo:table-row>
            </xsl:when>
            <xsl:when test="$rowcnt = $breakrow and ancestor::fo:table[1]/fo:table-header/fo:table-row[1]/fo:table-cell[1]/fo:block/text() = 'HEADER_COL1'">
                <fo:table-row break-before="page"/>
            </xsl:when>
            <xsl:otherwise>
                <fo:table-row/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@*"/>
            <xsl:apply-templates select="node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

结果是这样的：

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">

    <fo:page-sequence force-page-count="no-force" master-reference="first" initial-page-number="1">

我传入了 12 作为参数，并假设你只有一个位置......第 12 行。您当然可以使用 "mod" 并每隔 12 行执行一次或任何您想要的操作。

例如：

 <xsl:when test="$rowcnt mod $breakrow = $breakrow - 1 and ancestor::fo:table[1]/fo:table-header/fo:table-row[1]/fo:table-cell[1]/fo:block/text() = 'HEADER_COL1'">

当然，您也可以只添加行以获得所有单元格内容输出。
