通配符或字符串模式如何与 XSLTv1.0 匹配

Question

我的XML数据包含以下内容：

<Cookies>
</Cookie>
<Cookie name="PD_STATEFUL_2707f5b6-48e3-11e8-bb87-000c2953888d">
<Value>%2Fportal</Value>
<Path>/</Path><Domain></Domain><Expires></Expires><Secure>0</Secure> 
<HTTPOnly>0</HTTPOnly>
</Cookie>
<Cookie name="PD_STATEFUL_2808f5b6-48e3-11e8-bb87-000c2953180d">
<Value>%2Fwasapp</Value>
<Path>/</Path><Domain></Domain><Expires></Expires><Secure>0</Secure> 
<HTTPOnly>0</HTTPOnly>
</Cookie>
</Cookies>

使用 XLSTv1.0，如何修改以下代码以设置以 PD_STATEFUL_* 开头的所有 cookie 的属性，而不是对每个特定的 cookie 名称进行编码？

<xsl:template match="//HTTPResponse/Cookies">
<xsl:if test="Cookie/@name='PD_STATEFUL_2707f5b6-48e3-11e8-bb87-000c2953180d'">
<Cookie action="update" name="PD_STATEFUL_2707f5b6-48e3-11e8-bb87-000c2953180d">
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
</xsl:if>
<xsl:if test="Cookie/@name='PD_STATEFUL_2808f5b6-48e3-11e8-bb87-000c2953180d'">
<Cookie action="update" name="PD_STATEFUL_2808f5b6-48e3-11e8-bb87-000c2953180d">
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
</xsl:if>
</xsl:template>

Answer 1

由于我不确定您的预期输出，因此我提供了 2 个样式表：

1(保持Cookie节点的结构相同，只需将元素的值更改为Secure和HTTPOnly1并添加action="update"属性

2( 在添加action="update"属性并将Secure和HTTPOnly的值更改为1的基础上，删除Cookie节点的所有其他子节点

输入：

::::::::::::::
cookies.xml
::::::::::::::
<?xml version="1.0" encoding="utf-8"?>
<Cookies>
<Cookie name="PD_STATEFUL_2707f5b6-48e3-11e8-bb87-000c2953888d">
<Value>%2Fportal</Value>
<Path>/</Path>
<Domain/>
<Expires/>
<Secure>0</Secure>
<HTTPOnly>0</HTTPOnly>
</Cookie>
<Cookie name="PD_STATEFUL_2808f5b6-48e3-11e8-bb87-000c2953180d">
<Value>%2Fwasapp</Value>
<Path>/</Path>
<Domain/>
<Expires/>
<Secure>0</Secure>
<HTTPOnly>0</HTTPOnly>
</Cookie>
</Cookies>

案例1

样式表：

::::::::::::::
cookies.xsl
::::::::::::::
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Cookie[starts-with(@name,'PD_STATEFUL_')]">
<Cookie action="update" name="{./@name}">
<xsl:apply-templates select="@*|node()"/>
</Cookie>
</xsl:template>
<xsl:template match="Cookie[starts-with(@name,'PD_STATEFUL_')]/Secure/text()">1</xsl:template>
<xsl:template match="Cookie[starts-with(@name,'PD_STATEFUL_')]/HTTPOnly/text()">1</xsl:template>
</xsl:stylesheet>

解释：

复制每个节点/属性，然后在到达符合条件的节点时Cookie[starts-with(@name,'PD_STATEFUL_')]添加属性action="update"使用相同的属性name="{./@name}"，然后在到达Cookie[starts-with(@name,'PD_STATEFUL_')]/Secure/text()时复制此元素下的所有内容，Cookie[starts-with(@name,'PD_STATEFUL_')]/HTTPOnly/text()将触发模板并将值设置为 1。其他不遵守starts-with(@name,'PD_STATEFUL_')的 Cookie 将不受此更改的影响。

输出：

$xsltproc cookies.xsl cookies.xml | xmllint --format -                                                                         
<?xml version="1.0"?>
<Cookies>
<Cookie action="update" name="PD_STATEFUL_2707f5b6-48e3-11e8-bb87-000c2953888d">
<Value>%2Fportal</Value>
<Path>/</Path>
<Domain/>
<Expires/>
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
<Cookie action="update" name="PD_STATEFUL_2808f5b6-48e3-11e8-bb87-000c2953180d">
<Value>%2Fwasapp</Value>
<Path>/</Path>
<Domain/>
<Expires/>
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
</Cookies>

案例2：

样式表：

::::::::::::::
cookies2.xsl
::::::::::::::
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Cookie[starts-with(@name,'PD_STATEFUL_')]">
<Cookie action="update" name="{./@name}">
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
</xsl:template>
</xsl:stylesheet>

解释：

在这里，当到达尊重Cookie[starts-with(@name,'PD_STATEFUL_')的节点时 我们将节点内容覆盖到

<Cookie action="update" name="{./@name}">
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>

因此，其他子节点将丢失。

输出：

$ xsltproc cookies2.xsl cookies.xml | xmllint --format -
<?xml version="1.0"?>
<Cookies>
<Cookie action="update" name="PD_STATEFUL_2707f5b6-48e3-11e8-bb87-000c2953888d">
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
<Cookie action="update" name="PD_STATEFUL_2808f5b6-48e3-11e8-bb87-000c2953180d">
<Secure>1</Secure>
<HTTPOnly>1</HTTPOnly>
</Cookie>
</Cookies>
