使用XSLT基于特定条件转换XML

标签： xslt

以下是我的要求。

1）我希望根据评估为true的特定条件将元素“错误”添加为最后一个元素。 2）我希望在'quote_or_print'元素之后添加元素'generic_quote_ind'，基于其他条件，如果得到的结果为true。

下面是我输入的XML，我编写的XSLT以及预期的输出XML。

使用这段代码，我可以添加'error'元素作为最后一个元素，但我无法在'quote_or_print'元素之后添加'generic_quote_ind'。

请指导我如何实现这个目标？

输入XML 

 <?xml version="1.0" encoding="utf-8"?>
<message xmlns="http://www.origoservices.com" xmlns:xsi="http://www.w3.org /2001/XMLSchema-instance">
<m_control>
    <control_timestamp>2013-06-06T14:55:37</control_timestamp>
    <initiator_id>ASL</initiator_id>
</m_control>
<m_content>
    <b_control>
        <quote_type>Comparison</quote_type>
        <quote_or_print>Quote And Print</quote_or_print>
        <message_version_number>3.7</message_version_number>
</b_control>
  <application>
    <product>
        <tpsdata>
            <service_type>QuickQuote</service_type>
            <quote_type>Standard</quote_type>
        </tpsdata>
    </product>
</application>
</m_content>
</message>

预期OutPut 

<?xml version="1.0" encoding="UTF-8"?>
<message xmlns="http://www.origoservices.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<m_control>
    <control_timestamp>2013-06-06T14:55:37</control_timestamp>
    <initiator_id>ASL</initiator_id>
</m_control>
<m_content>
    <b_control>
        <quote_type>Comparison</quote_type>
        <quote_or_print>Quote And Print</quote_or_print>
        <generic_quote_ind>Yes</generic_quote_ind>
        <message_version_number>3.7</message_version_number>
    </b_control>
<application>
    <product>
        <tpsdata>
            <service_type>QuickQuote</service_type>
            <quote_type>Standard</quote_type>
        </tpsdata>
    </product>
</application>
</m_content>
</message>

试试这个...... 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                              xmlns:o="http://www.origoservices.com"
                              exclude-result-prefixes="xsl o">
<xsl:output omit-xml-declaration="yes" indent="yes" />
<xsl:strip-space elements="*" />

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

<xsl:template match="o:b_control[
    ((../../o:m_control/o:initiator_id='ASK') or (o:generic_quote_ind='Yes')) and
    (../o:application/o:tpsdata/o:service_type='QuickResponse') and

 <xsl:copy>
  <xsl:apply-templates select="@*|node()" />
  <error xmlns="http://www.origoservices.com">unable to provide quote</error>
