Any ideas? Thanks in advance

Using Regex to validate a variable length string

Using Regex to validate a variable length string

I'm trying to validate a form field in Java using Regex, which can have 5
different format possibilities. I'm struggling to get this one working.
The string to be checked will be between 4-6 alphanumeric characters.
If it's 4 characters, it must be all numbers.
^\\d{4}$
If it's 5 characters, it can be all numbers, first position letter with 4
following numbers, or first 3 positions letters followed with 2 numbers.
^\\d{5}$
^[a-zA-Z]\\d{4}$
^[a-zA-Z]{3}\\d{2}$
And if it's 6 characters, it will be first position letter, 4 numbers, and
last another letter.
^[a-zA-Z]\\d{4}[a-zA-Z]$
I just can't seem to piece it all together though.

How to create Instance by java.lang.reflect.Type

How to create Instance by java.lang.reflect.Type

I want to set property of class by using reflect,

and my class have a List<Article> property.
i just get the generics type of the List<Artile> by below code
Method[] methods = target.getClass().getMethods();
String key = k.toString(), methodName = "set" + key;
Method method = getMethod(methods, methodName);
if (Iterable.class.isAssignableFrom(method.getParameterTypes()[0])) {
// at there, i get the generics type of list
// how can i create a instance of this type?
Type type = getGenericsType(method);
}
public static Method getMethod(Method[] methods, String methodName) {
for (Method method : methods) {
if (method.getName().equalsIgnoreCase(methodName))
return method;
}
return null;
}
private static Type getGenericsType(Method method) {
Type[] types = method.getGenericParameterTypes();
for (int i = 0; i < types.length; i++) {
ParameterizedType pt = (ParameterizedType) types[i];
if (pt.getActualTypeArguments().length > 0)
return pt.getActualTypeArguments()[0];
}
return null;
}

EDIT:
i just solved it with a stupid solution,
its instantiation generics type by using Class.forName();
the class name come from type.toString()
Type type = getGenericsType(method);
Class<?> genericsType = null;
try {
genericsType = Class.forName(getClassName(type));
// now, i have a instance of generics type
Object o = genericsType.newInstance();
} catch (Exception e) {
}
static String NAME_PREFIX = "class ";
private static String getClassName(Type type) {
String fullName = type.toString();
if (fullName.startsWith(NAME_PREFIX))
return fullName.substring(NAME_PREFIX.length());
return fullName;
}

Based on multiple criterias on parent's siblings

Based on multiple criterias on parent's siblings

I would like to know if I can combine at the same time an XPath looking
for the previous sibling of a certain class with a certain text and at the
same time a sibling at the same level with a certain text.
For example I would like to find the following cells:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160832)">Book</a></td>
by looking up a sibling of class sdawatt_hrdcell containing the text Spin
preceded by a td of class sdawatt_banner with the text Monday - 16
September 2013.
Or the following td:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160864)">Book</a></td>
if we look for the date of the 'Friday - 13 September 2013'.
Is this something doable in Xpath ?
