Extract a form parameter value

Content:

<form action="doit.jsp" method="post">

    <input type="hidden" name="myHiddenField" value="hidden information">

    Name:      <input name="cn" type="text" value="filled value"><br>

    <input name="myRadioField" value="val1" type="radio">Radio Value 1<br>

    <input name="myRadioField" value="val2" type="radio" checked="checked">

    Radio Value 2<br>

    <input type="checkbox" name="myCheckbox" value="checkBoxValue" checked="checked">

    A checkbox<br>

    <select name="dropDownList">

      <option value="val1">list choice 1

      <option value="val2" selected>list choice 2

      <option value="val3">list choice 3

    </select><br>

    <input value="Send" type="submit"><input type="reset">

</form>

The form looks like this:

Extract from a text field

Content (value in quotation marks): <input name="cn" type="text" value="filled value">

Regex: <input name="cn" type="text" value="([^"]*)"

Content (value without quotation marks): <input name="cn" type="text" value=myvalue>

Regex: <input name="cn" type="text" value=([^\s>]*)

Comment: In each case, the parentheses define the group whose value may be extracted in NeoLoad using $1$.

Advanced case: Where the web page contains several forms with text fields of the same name, the regex must contain the following:

<form action="doit.jsp" method="post">(.|\s)*?<input type=hidden name=myHiddenField value="([^"]*)"

Comments:

• (.|\s)*? means "any character, including the new line character". "?" means that the first "<input" must be used.
• ([^"]*) means "any character except the quotation mark character '"' ". The parentheses are required to define a group. The first group ($1$ in NeoLoad), refers to ''(.|\s)*". However, the second group ($2$ in NeoLoad) also needs to be taken into account.

Extract from a hidden field

The hidden field is dealt with in a similar way to a normal text field. The input type value "hidden" is substituted for "text".

Content: <input type=hidden name=myHiddenField value="hidden information" >

Regex: <input type=hidden name=myHiddenField value="([^"]*)"

Extract from a radio button

Content: <input name="myRadioField" value="val2" type="radio" checked="checked" >Radio Value 2

Regex: <input name="myRadioField" value="([^"]*)" type="radio" checked="checked" >([^<\n]*)

Comments:

• The radio button selected is the one with the checked attribute set to "checked".
• ([^"]*) means "any character except the quotation mark character '"' ".
• ([^<\n]*)means "any character except '<' and the new line character ".
• The parentheses are required to define a group. The first group refers to the value and the second refers to the radio button label. Therefore, use $1$ in NeoLoad to extract the value and $2$ to extract the label.

Extract from a checkbox

Content: <input type="checkbox" value="checkBoxValue" name="myCheckbox" checked="checked">A checkbox

Regex: <input type="checkbox" value="([^"]*)" name="myCheckbox" checked="checked">([^<\n]*)

Comments:

• The checkbox selected is the one with the checked attribute set to "checked".
• ([^"]*)means "any character except the quotation mark character '"' ".
• ([^<\n]*)means "any character except '<' and the new line character ".
• The parentheses are required to define a group. The first group refers to the value and the second refers to the checkbox label. Therefore, use $1$ in NeoLoad to extract the value and $2$ to extract the label.

Extract from a list

Content:

<select name="dropDownList">

  <option value="val1">list choice 1

  <option value="val2" selected>list choice 2

  <option value="val3">list choice 3

</select>

Regex: <select name="dropDownList">(.|\n)*<option value="([^"]*)" selected>([^<\n]*)

Comments:

• The list item selected is the one with the selected attribute set.
• (.|\n)* means "any character, including the new line character".
• [^"]*) means "any character except the quotation mark character '"' ".
• ([^<\n]*)means "any character except '<' and the new line character ".
• The parentheses are required to define a group. The first group in the regex is redundant; the second refers to the value and the third to the list item label. Therefore, use $2$ in NeoLoad to extract the value and $3$ to extract the label.
