我有xml如下:
<Result>
<customer>
<id>123abc</id>
<lastName>John1</lastName>
<firstName>Doe1</firstName>
<phone>1234578900</phone>
</customer>
<customer>
<id>456</id>
<lastName>John2</lastName>
<firstName>Doe2</firstName>
<phone>1234587900</phone>
</customer>
<customer>
<id>789</id>
<lastName>John3</lastName>
<firstName>Doe3</firstName>
<phone>1234467900</phone>
</customer>
<customer>
<id>012</id>
<lastName>John4</lastName>
<firstName>Doe4</firstName>
<phone>1236567900</phone>
</customer>
<customer>
<id>012jkl</id>
<lastName>John5</lastName>
<firstName>Doe5</firstName>
<phone>1236567900</phone>
</customer>
<customer>
<id>235</id>
<lastName>John6</lastName>
<firstName>Doe6</firstName>
<phone>1232567900</phone>
</customer>
<customer>
<id>568</id>
<lastName>John7</lastName>
<firstName>Doe7</firstName>
<phone>1237567900</phone>
</customer
</Result>
我只需要输出5个客户结果,其中id是数字。如果请求少于5个客户,那么我需要输出所有。但如果请求超过5,我只需要输出5个结果,其中id是数字。如何使用样式表
实现这一目标预期产出:
<Result>
<customer>
<id>456</id>
<lastName>John2</lastName>
</customer>
<customer>
<id>789</id>
<lastName>John3</lastName>
</customer>
<customer>
<id>012</id>
<lastName>John4</lastName>
</customer>
<customer>
<id>235</id>
<lastName>John6</lastName>
</customer>
<customer>
<id>568</id>
<lastName>John7</lastName>
</customer>
</Result>
我的xsl:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/Result">
<xsl:copy>
<xsl:for-each select="customer[position() <= 5]">
<xsl:copy>
<xsl:if test="number(id/text())">
<xsl:copy-of select="id | lastName"/>
</xsl:if>
</xsl:copy>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
这只返回前3个元素。我需要做出哪些调整才能获得客户ID为数字的5个ID
答案 0 :(得分:1)
要返回第一个(按文档顺序)5个<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/Result">
<xsl:copy>
<xsl:for-each select="customer[not(translate(id, '0123456789', ''))][position() <= 5]">
<xsl:copy>
<xsl:copy-of select="id | lastName"/>
</xsl:copy>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
仅包含数字的客户:
XSLT 1.0
var x = document.getElementById('input1').value;
var y = document.getElementById('input2').value;
if (x.length > 0 && y.length > 0) {
//execute code
}
