使用Javascript代码将Cognos XML Schema文件转换为XML [英] Converting a Cognos XML Schema file to XML using Javascript code

问题描述

我在线上找到了许多可以帮助您完成此操作的转换器，但是我找不到能够轻松实现的任何源代码。我想知道是否有人会为我提供建议，甚至为我提供可以帮助我完成此任务的代码。我正在尝试转换为XML，因此将更易于解析。

I found many "converters" online that will do this for you, but I haven't been able to find any source code that I can easily implement. I was wondering if anyone would be so kind to provide me with suggestions or even provide me with code that will do this task for me. I am trying to convert to XML so it will be easier to parse.

推荐答案

此Xslt从任意Cognos报告中剥离了任何架构元数据- Xml输出方法-并创建具有从元数据中提取的名称的结果元素：

This Xslt strip any schema metadata from arbitrary Cognos reports - Xml output method - and create result elements with names extracted from the metadata:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns="http://tempuri.org/" xmlns:cog="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="yes" />

    <xsl:template match="//comment()" />

    <xsl:template match="/">
        <xsl:apply-templates />
    </xsl:template>

    <xsl:template match="cog:dataset">
        <rows>
            <xsl:apply-templates />
        </rows>
    </xsl:template>

    <xsl:template match="cog:metadata">
        <xsl:apply-templates />
    </xsl:template>

    <xsl:template match="cog:item">
        <xsl:apply-templates />
    </xsl:template>

    <xsl:template match="@name | @type | @length | @precision" />

    <xsl:template match="cog:data">
        <xsl:apply-templates />
    </xsl:template>

    <xsl:template match="cog:row">
        <row>
            <xsl:apply-templates />
        </row>
    </xsl:template>

    <xsl:template match="cog:value">
        <xsl:variable name="currentposition" select="count(./preceding-sibling::cog:value)+1" />
        <xsl:variable name="currentname" select="//cog:metadata/cog:item[$currentposition]/@name" />
        <xsl:element name="{$currentname}">
            <xsl:apply-templates />
        </xsl:element>
    </xsl:template>

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

但是，如果您想使Cognos应用服务器端转换，您必须选择 XHTML 输出方法，该方法会使转换变得容易一些，因为每个字段都将使用其实际名称而不是 value 。

If however you want to make Cognos apply a server-side transformation, you'll have to choose the XHTML output method which will make the transformation a little easier since each field will carry its actual name instead of value.
