我当前的xslt如下所示：
<？xml version =1.0encoding =ISO-8859-1？>
< xsl：transform version =1.0xmlns：xsl =http://www.w3.org/1999/XSL/Transformxmlns：exslt =http://exslt.org/common >

如果我假设最大列数，并且列标题可以是合法的qnames， / p>
当我超过了我假设的100个限制和列标题包含空格时，它开始失败。
如何创建一个使用通配符的转换，如何从列标题中删除空格和非法字符，使它们成为合法的qnames？
感谢
解决方案
此转换：
code>< xsl：stylesheet version =1.0
xmlns：xsl =http://www.w3.org/1999/XSL/Transform>
< xsl：output omit-xml-declaration =yesindent =yes/>
< xsl：strip-space elements =*/>
< xsl：variable name =vAlphanumselect =
concat（'ABCDEFGHIJKLMNOPQRSTUVWXYZ'，
'abcdefghijklmnopqrstuvwxyz'，
'_0123456789'
）
/>
< xsl：variable name =vRepsselect =
'_____________________________________'/>
< xsl：key name =kColNameByCode
match =report_header / * / text（）
use =name（..）/>
< xsl：template match =node（）| @ *>
< xsl：copy>
< xsl：apply-templates select =node（）| @ */>
< / xsl：copy>
< / xsl：template>
< xsl：template match =report_row / *>
< xsl：variable name =vNameTextselect =
key（'kColNameByCode'，name（））/>
< xsl：variable name =vElNameselect =
translate（$ vNameText，
translate（$ vNameText，$ vAlphanum，''），
$ vReps）
/>
< xsl：element name ={$ vElName}>
< xsl：value-of select =。/>
< / xsl：element>
< / xsl：template>
< xsl：template match =report_header/>
< / xsl：stylesheet>
应用于提供的XML文档：
< report>
< report_header>
< c1> desc< / c1>
< c2>公司名称< / c2>
< c3> pr num< / c3>
< c4> cdate< / c4>

< c7>活动< / c7>
< c8> IT< / c8>

产生想要的正确结果：
< report>
< report_row>
< desc />
< pr_name> IT项目邮件验证< / pr_name>
< pr_num> IT-0000021< / pr_num>

请注意：
$ b b
-
转换可将任何数量的不同非字母数字字符的文本成功转换为语法正确的XML名称。
li>

My transform works if I assume a maximal number of columns and the column headers can be legal qnames.
It started failing when I got more than the 100 limit I had assumed and column headers with spaces in them.
How do I create a transform that uses wildcards instead and how do I strip spaces and illegal characters from the column headers to make them legal qnames?
Thanks
解决方案
This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="vAlphanum" select=
"concat('ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'abcdefghijklmnopqrstuvwxyz',
'_0123456789'
)
"/>
<xsl:variable name="vReps" select=
"'_____________________________________'"/>
<xsl:key name="kColNameByCode"
match="report_header/*/text()"
use="name(..)"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="report_row/*">
<xsl:variable name="vNameText" select=
"key('kColNameByCode', name())"/>
<xsl:variable name="vElName" select=
"translate($vNameText,
translate($vNameText,$vAlphanum,''),
$vReps)
"/>
<xsl:element name="{$vElName}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:template>
<xsl:template match="report_header"/>
</xsl:stylesheet>
when applied to the provided XML document:
<report>
<report_header>
<c1>desc</c1>
<c2>pr name</c2>
<c3>pr num</c3>
<c4>cdate</c4>
<c5>phase</c5>
<c6>stype</c6>
<c7>status</c7>

produces the wanted, correct result:

<status>Active</status>

<location>/IT/BIOMED</location>
</report_row>
</report>
Do note:
The transformation successfully converts any text with any number of different non-alphanumeric characters to a syntactically-correct XML name.
Efficiency is achieved using keys.
