XSLT 转换不保留属性 [英] XSLT transformation not retaining the attributes
问题描述
我们有以下 XML 需要查找和替换 src 属性参数中的路径
<ul><字体>测试示例字体测试</font><img src="/assets/rep/myimage.png">测试<img src="/assets/rep/myimage.png" height="20px">测试
我的XSLT如下
<img src="{$imagesrc}"/></xsl:模板></xsl:stylesheet>
XSLT 再现适用于
测试
但不是为了
测试
我尝试添加 match="@src[parent::img]" 但这也不起作用.您能否让我知道我在 XSLT 中缺少什么以保留属性并仅修改src"属性?
将您当前的逻辑更改为这样的模板:
<预><代码>...<xsl:template match="img"><xsl:copy><xsl:apply-templates select="@* | node()"/></xsl:copy></xsl:模板><xsl:template match="img/@src"><xsl:attribute name="src"><xsl:value-of select="replace(.,'/assets/rep/','/images/')"/></xsl:attribute></xsl:模板>...在您的尝试中,您创建了一个元素 而您的上下文节点是一个属性
@src
.使用提供的示例,您会没事的!
We have the following XML that we need to find and replace the path in src attribute parameters
<?xml version="1.0"?>
<ul>
<font> test sample font test </font>
<img src="/assets/rep/myimage.png"> test</img>
<img src="/assets/rep/myimage.png" height="20px"> test</img>
</ul>
My XSLT is as follows
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- remove disallowed elements but keep its children -->
<xsl:template match="font">
<xsl:apply-templates></xsl:apply-templates>
</xsl:template>
<xsl:template match="@src">
<xsl:variable name="imagesrc" select="replace(.,'/assets/rep/','/images/')"/>
<img src="{$imagesrc}" />
</xsl:template>
</xsl:stylesheet>
The XSLT rendition works for
<img src="/assets/rep/myimage.png"> test</img>
but not for
<img src="/assets/rep/myimage.png" height="20px"> test</img>
I tried to add match="@src[parent::img]" but that does not work either. Can you let me know what I am missing in my XSLT to retain the attributes and ONLY modify "src" attributes?
Change your current logic to templates like this:
...
<xsl:template match="img">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="img/@src">
<xsl:attribute name="src">
<xsl:value-of select="replace(.,'/assets/rep/','/images/')"/>
</xsl:attribute>
</xsl:template>
...
In your try, you created an element <img>
while your context-node is an attribute @src
. With the provided example you will be fine!
