Question

我需要预处理在jMeter中使用CSV数据集填充的SOAP请求（使用HTTP请求）。某些绑定变量为null，这是预期的，但是我正在测试的服务也对这些元素执行验证。

过去也有类似的问题（JMeter - Remove empty elements in SOAP request），但就我而言，我并不是只想清除要清除整个块的空白元素。

示例：我想要这个

<table>
    <name>businessLicenceGroup</name>
    <tableRow>
        <sequence>1</sequence>
        <field>
            <sequence>0</sequence>
            <name>authority</name>
            <value>AD01</value>
        </field>
        <field>
            <sequence>1</sequence>
            <name>licenceNumber</name>
            <value></value>
        </field>
    </tableRow>
</table>

成为

<table>
    <name>businessLicenceGroup</name>
    <tableRow>
        <sequence>1</sequence>
        <field>
            <sequence>0</sequence>
            <name>authority</name>
            <value>AD01</value>
        </field>
    </tableRow>
</table>

Answer 1

查找空对象并删除其父节点的参考代码如下：

def before = prev.getResponseDataAsString()
log.info('Before: ' + before)
def xml = new groovy.util.XmlParser().parseText(before)
def nodesWithoutText = xml.'**'.findAll { it.name() && !it.text() }
def removeNode = { node ->
    def field = node.parent()
    def tableRow = field.parent()
    tableRow.remove(field)
}
nodesWithoutText.each{removeNode(it)}
log.info('After: ' + groovy.xml.XmlUtil.serialize(xml))

上面的代码假定您的示例XML来自Sampler的响应，需要放入JSR223 PostProcessor

也许您可以将此普通脚本用于JSR223 PreProcessor。它基于以下文章。看待。结果与输入xml格式不同。

log.info("XML before removing Node: " + xml);

def table = new XmlParser().parseText(xml);

log.info("Parsed XML before removing Node: " + table);

log.info("Node to remove: " + table.tableRow.field[1]);
// remove the node by replacement with empty element
table.tableRow.field[1].replaceNode {};

// Create Output

def xmlOutput = new StringWriter()
def xmlNodePrinter = new XmlNodePrinter(new PrintWriter(xmlOutput))
xmlNodePrinter.print(table)

log.info("Parsed XML after removing Node: " + xmlOutput.toString());
