XSL-FO文档：在具体的fo：table-row中插入break-before =“ page”属性

时间：2018-11-10 18:25:18

标签： c# xml visual-studio-2008 .net-3.5 xsl-fo

我有一个XSL-FO文档。该文档有很多fo：table嵌套。 有一个内部fo：table，它具有9列和很多行，在此示例中，第一行代表表头，其他行，内容从1到20。在下面的示例中，您可以看到，作为注释，对于每个FOPTable（fo：table），它都表示一个唯一的标识符，但是对于同一张表，此标识符并不总是相同的。它是由创建此XSL-FO文档的应用程序随机生成的。

我的问题是：我想找到其第一列标题值设置为HEADER_COL1的表（此值始终相同），在此示例中，标识为id：997的表（无法搜索的表的内容）根据此标识符，因为每次应用程序创建XSL-FO文档时它都会随机更改）。找到所需的表格后，请在下面进行操作：

  1. 如何为具体插入属性break-before =“ page” fo：表行项目？
  2. 我想获取此内部表的行数。

例如：

例如，如果要为第15个fo：table-row项插入此属性，该怎么做？我想要一个经过参数化的通用方法，该方法以一个数字作为参数，该数字指示fo：table-row将此属性放在何处。

我知道我可以使用以下内容阅读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。

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

获取数据并删除所有单元格和其他不重要的内容，只需将身份XSL应用于XSL FO并仅修改目标行即可。

以该XML开头：

                            <fo:table-row/>                            
                            <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，它将按原样输出所有内容，除了在目标表的第12行插入一个分页符的模板之外：

<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，并假设您只有一个地方，即第12行。您当然可以使用“ mod”并每12行执行一次，或执行您想要的任何操作。

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，您可以将其添加到行中以获取所有单元格内容的输出。
