在 XSLT 中保留数据中的空间

Question

我有这样的数据

<Table1>
 <row_description>Low Touch</row_description>
 <_x0038_ />
 <_x0039_ />
 <_x0031_0 />
 <_x0031_1 />
 <_x0031_2 />
</Table1>
<Table1>
 <row_description>    DMA/ALGO</row_description>
 <_x0038_ />
 <_x0039_ />
 <_x0031_0 />
 <_x0031_1 />
 <_x0031_2 />
</Table1>
<Table1>
 <row_description>    PT</row_description>
 <_x0038_ />
 <_x0039_ />
 <_x0031_0 />
 <_x0031_1 />
 <_x0031_2 />
</Table1>

而我的 XSLT 就是这样做的

<xsl:for-each select="*">
    <TableCell Padding="10,1" BorderThickness="1,1,1,1" BorderBrush="#FF888888">
        <xsl:if test="position()=1">
            <Paragraph>
                <Span>
                    <Run>
                      <xsl:value-of select="text()" />
                    </Run>
                </Span>
            </Paragraph>
        </xsl:if>
        <xsl:if test="position()>1">
            <Paragraph TextAlignment="Right">
                <Span>
                    <Run>
                        <xsl:value-of select="text()"/>
                    </Run>
                </Span>
            </Paragraph>
        </xsl:if>
    </TableCell>
</xsl:for-each>

但它正在删除我的文本 PT 到 PT 之前的空间。如何保留数据中的空间？

Answer 1

在您的 XSLT 中使用：

<xsl:preserve-space elements="*" />

见：http://www.w3schools.com/xsl/el_preserve-space.asp

当我有以下输入 XML 时：

<?xml version="1.0" encoding="UTF-8"?>
<data>
    <Table1>
        <row_description>Low Touch</row_description>
        <_x0038_/>
        <_x0039_/>
        <_x0031_0/>
        <_x0031_1/>
        <_x0031_2/>
    </Table1>
    <Table1>
        <row_description>    DMA/ALGO</row_description>
        <_x0038_/>
        <_x0039_/>
        <_x0031_0/>
        <_x0031_1/>
        <_x0031_2/>
    </Table1>
    <Table1>
        <row_description>    PT</row_description>
        <_x0038_/>
        <_x0039_/>
        <_x0031_0/>
        <_x0031_1/>
        <_x0031_2/>
    </Table1>
</data>

我使用以下 XSLT：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html" encoding="UTF-8" indent="yes"/>
    <xsl:preserve-space elements="*" />

    <xsl:template match="@*|node()">
        <xsl:apply-templates select="@*|node()" />
    </xsl:template>

    <xsl:template match="Table1">
        <xsl:for-each select="*">
            <TableCell Padding="10,1" BorderThickness="1,1,1,1" BorderBrush="#FF888888">
                <xsl:if test="position()=1">
                    <Paragraph>
                        <Span>
                            <Run>
                              <xsl:value-of select="text()" />
                            </Run>
                        </Span>
                    </Paragraph>
                </xsl:if>
                <xsl:if test="position()>1">
                    <Paragraph TextAlignment="Right">
                        <Span>
                            <Run>
                                <xsl:value-of select="text()"/>
                            </Run>
                        </Span>
                    </Paragraph>
                </xsl:if>
            </TableCell>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

输出按预期显示：

<TableCell Padding="10,1" BorderThickness="1,1,1,1" BorderBrush="#FF888888">
    <Paragraph><Span><Run>Low Touch</Run>
        </Span></Paragraph>

值<Run> PT</Run> 中仍然有空格。作为 XSLT 处理器，我使用了 Altova XMLSpy。

Answer 2

我是 OP，我这样做是为了解决我的问题

<Run xml:space="preserve"><xsl:value-of select="text()" /></Run>

注意：写完xml:space="preserve"后，请确保<xsl:value-of select="text()" />在同一行。如果我们这样写

<Run xml:space="preserve">
    <xsl:value-of select="text()" />
</Run>

它还会将 xsl 的缩进视为文本，正如我们所说的以保留空间。
