将 HL7 段转换为 XML [英] Converting and HL7 segment to XML
问题描述
我有一个 XML,我们能够使用 HAPI 库生成它并使用 XSL 来更改 XML 的格式.我正在使用以下模板.当前模板查看 OBX.5 段的数字值,然后解释 OBX6(度量单位).但是,当 OBX6 来自某个客户端的样式时,我也尝试将它们解释为重复,中间带有插入符号 ^
(例如:%^%
或 <代码>mL^mL代码>).我当前的模板忽略了这一点,但我希望能够在 ^
之前或之后获取段子字符串的值.
i have an XML that we were able to generate using HAPI libraries and use XSL to change the format of the XML. I am using the following template. The current template looks at the OBX.5 segment for a digital value and then interprets the OBX6 (units of measure). However I am trying to also interpret the OBX6 when they come from one of the clients in a style as duplicates with the caret ^
in between (ex: %^%
or mL^mL
). My current template ignores this but I would like to be able to get the value of the segment substring before or after the ^
.
<xsl:template match="hl7:OBX.6[matches(./../hl7:OBX.5, '^\d+(\.\d+)?$') and index-of($percentList, .) or index-of($mgdlList, .) or index-of($mlList, .) or index-of($mmList, .) or index-of($mgList, .))]">
<result><xsl:value-of select="./../hl7:OBX.5" /></result>
<xsl:when test="index-of($percentList, .)">
<units>%</units>
</xsl:when>
...
<xsl:when test="index-of($mlList, .)">
<units>ml</units>
</xsl:when>
<xsl:otherwise>
<units><xsl:value-of select="./hl7:CE.1" /></units>
</xsl:otherwise>
...
</xsl:template>
结果应该产生
<result>38.0</result>
<units>%</units>
来自
<OBX.5>38.0</OBX.5>
<OBX.6>
<CE.1>%^%</CE.1>
</OBX.6>

推荐答案
使用:
tokenize(hl7:CE.1, '\^')[1]
这是一个简单的基于 XSLT 2.0 的验证:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="OBX.6">
<xsl:sequence select="tokenize(CE.1, '\^')[1]"/>
</xsl:template>
<xsl:template match="text()"/>
</xsl:stylesheet>
当此转换应用于以下 XML 文档时(派生自提供的 XML 片段并使其格式正确):
when this transformation is applied on the following XML document (derived from the provided XML fragment and made well-formed):
<t>
<OBX.5>38.0</OBX.5>
<OBX.6>
<CE.1>%^%</CE.1>
</OBX.6>
</t>
产生了想要的、正确的结果:
