如何在运行时更改web查询参数值的xslt（xml包）中重新分配参数值

目前，我正在处理ASPDNSF CMS xml包，并试图更改web查询参数pageZise的默认值。 我的pronblm是当我第一次搜索产品时，页面大小为0，它显示了大约200个产品的产品列表，因此我想检查页面大小是否为0，然后它应该设置页面大小pagenumber*12

以下是我的代码web查询代码：

<webquery name="searchresults" RetType="xml" timeout="30">
    <url><![CDATA[{SmartSearch}&searchTerm={entityName}ID:{entityID}&searchString={searchString}&sortField={sortField}&pageNumber={pageNumber}&pageSize={pageSize}&facetQuery={facet}]]></url>
    <querystringreplace replaceTag="{SmartSearch}" replacetype="webconfig" replaceparamname="SmartSearchURL" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{searchString}" replacetype="runtime" replaceparamname="SearchTerm" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{entityID}" replacetype="runtime" replaceparamname="EntityID" defvalue="" validationpattern=""/>
    <!-- if the EntityID is missing, then get rid of the whole searchTerm: -->
    <querystringreplace replaceTag="searchTerm={entityName}ID:&amp;" replacetype="justreplace" replaceparamname="N/A" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{entityName}" replacetype="runtime" replaceparamname="EntityName" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{pageNumber}" replacetype="request" replaceparamname="pageNumber" defvalue="1" validationpattern=""/>
    <querystringreplace replaceTag="{pageSize}" replacetype="request" replaceparamname="pageSize" defvalue="0" validationpattern=""/>
    <querystringreplace replaceTag="{facetGroup}" replacetype="request" replaceparamname="facetgroup" defvalue="ManufacturerID" validationpattern=""/>
    <querystringreplace replaceTag="{facet}" replacetype="request" replaceparamname="facet" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{sortField}" replacetype="request" replaceparamname="sortField" defvalue="" validationpattern=""/>
  </webquery> 

我正试图通过以下代码实现目标

<xsl:param name="pageSize" select="/root/searchresults/hits/pagesize"></xsl:param>

      <xsl:param name="pageSize">
        <xsl:choose>
          <xsl:when test="string(number(/root/searchresults/hits/pagesize)) != 'NaN'">
            <xsl:value-of select="/root/searchresults/hits/pagesize" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="30" />
          </xsl:otherwise>
        </xsl:choose>
      </xsl:param>

      <xsl:param name="pageNumber">
        <xsl:choose>
          <xsl:when test="/root/searchresults/hits/page/text()">
            <xsl:value-of select="/root/searchresults/hits/page" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="0" />
          </xsl:otherwise>
        </xsl:choose>
      </xsl:param>

谢谢你的建议：）

更改默认值只需更改webquery中每个querystringreplace的defvalue属性即可

基本上是下面的代码

<webquery name="searchresults" RetType="xml" timeout="30">
    <url><![CDATA[{SmartSearch}&searchTerm={entityName}ID:{entityID}&searchString={searchString}&sortField={sortField}&pageNumber={pageNumber}&pageSize={pageSize}&facetQuery={facet}]]></url>
    <querystringreplace replaceTag="{SmartSearch}" replacetype="webconfig" replaceparamname="SmartSearchURL" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{searchString}" replacetype="runtime" replaceparamname="SearchTerm" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{entityID}" replacetype="runtime" replaceparamname="EntityID" defvalue="" validationpattern=""/>
    <!-- if the EntityID is missing, then get rid of the whole searchTerm: -->
    <querystringreplace replaceTag="searchTerm={entityName}ID:&amp;" replacetype="justreplace" replaceparamname="N/A" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{entityName}" replacetype="runtime" replaceparamname="EntityName" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{pageNumber}" replacetype="request" replaceparamname="pageNumber" defvalue="0" validationpattern=""/>
    <querystringreplace replaceTag="{pageSize}" replacetype="request" replaceparamname="pageSize" defvalue="30" validationpattern=""/>
    <querystringreplace replaceTag="{facetGroup}" replacetype="request" replaceparamname="facetgroup" defvalue="ManufacturerID" validationpattern=""/>
    <querystringreplace replaceTag="{facet}" replacetype="request" replaceparamname="facet" defvalue="" validationpattern=""/>
    <querystringreplace replaceTag="{sortField}" replacetype="request" replaceparamname="sortField" defvalue="" validationpattern=""/>
</webquery>
