selector

public static Filter selector(java.lang.String selector)

A filter that returns all elements matched by a given selector.

In most cases, this is the same as calling tag(String). In Match.find(String), the following CSS-style selector syntax elements are also supported:

Selector pattern	meaning
*	any element
E	an element of type E
E[foo]	an E element with a "foo" attribute
E[foo="bar"]	an E element whose "foo" attribute value is exactly equal to "bar"
E[foo~="bar"]	an E element whose "foo" attribute value is a list of whitespace-separated values, one of which is exactly equal to "bar"
E[foo^="bar"]	an E element whose "foo" attribute value begins exactly with the string "bar"
E[foo$="bar"]	an E element whose "foo" attribute value ends exactly with the string "bar"
E[foo*="bar"]	an E element whose "foo" attribute value contains the substring "bar"
E[foo\|="en"]	an E element whose "foo" attribute has a hyphen-separated list of values beginning (from the left) with "en"
E:root	an E element, root of the document
E:first-child	an E element, first child of its parent
E:last-child	an E element, last child of its parent
E:only-child	an E element, only child of its parent
E:empty	an E element that has no children (including text nodes)
E#myid	an E element with ID equal to "myid".
E F	an F element descendant of an E element
E > F	an F element child of an E element
E + F	an F element immediately preceded by an E element
E ~ F	an F element preceded by an E element

Note that due to the presence of pseudo selectors, such as :root, :empty, etc, namespaces are not supported in selectors. Use jOOX's XPath functionality provided in Match.xpath(String) along with Match.namespaces(java.util.Map) if your XML document contains namespaces

tag
```
public static FastFilter tag(java.lang.String tagName)
```
A filter that returns all elements with a given tag name
This is the same as calling tag(tagName, true)

See Also:

tag(String, boolean)

tag
```
public static FastFilter tag(java.lang.String tagName,
                             boolean ignoreNamespace)
```
A filter that returns all elements with a given tag name
This method allows for specifying whether namespace prefixes should be ignored. This is particularly useful in DOM Level 1 documents, which are namespace-unaware. In those methods Document.getElementsByTagNameNS(String, String) will not work, as elements do not contain any localName.

Parameters:

tagName - The tag name to match. Use * as a special tag name to match all tag names

ignoreNamespace - Whether namespace prefixes can be ignored. When set to true, then the namespace prefix is ignored. When set to false, then tagName must include the actual namespace prefix.

namespacePrefix
```
public static FastFilter namespacePrefix(java.lang.String namespacePrefix)
```
A filter that returns all elements with a given namespace prefix
null and the empty string are treated equally to indicate that no namespace prefix should be present.

namespaceURI
```
public static FastFilter namespaceURI(java.lang.String namespaceURI)
```
A filter that returns all elements with a given namespace URI
null and the empty string are treated equally to indicate that no namespace URI should be present.
This only works if the underlying document is namespace-aware

matchText
```
public static FastFilter matchText(java.lang.String regex)
```
A filter that returns all elements whose text content matches a given regex

See Also:

Pattern.matches(String, CharSequence)

matchAttr

public static FastFilter matchAttr(java.lang.String name,
                                   java.lang.String valueRegex)

A filter that returns all elements whose text content matches a given regex

See Also:: Pattern.matches(String, CharSequence)

matchTag
```
public static FastFilter matchTag(java.lang.String regex)
```
A filter that returns all elements whose tag name matches a given regex
This is the same as calling matchTag(regex, true)

See Also:

Pattern.matches(String, CharSequence)

matchTag
```
public static FastFilter matchTag(java.lang.String regex,
                                  boolean ignoreNamespace)
```
A filter that returns all elements whose tag name matches a given regex
This method allows for specifying whether namespace prefixes should be ignored. This is particularly useful in DOM Level 1 documents, which are namespace-unaware. In those methods Document.getElementsByTagNameNS(String, String) will not work, as elements do not contain any localName.

Parameters:

regex - The regular expression to use for matching tag names.

ignoreNamespace - Whether namespace prefixes can be ignored. When set to true, then the namespace prefix is ignored. When set to false, then regex must also match potential namespace prefixes.

See Also:

Pattern.matches(String, CharSequence)

attr

public static FastFilter attr(java.lang.String name)

A filter that returns all elements with a given attribute

content
```

```

The resulting chained Each produces a new Each that can be used in the Match.each(Each) method. I.e. every node in a set of matched nodes will be passed to every chained Each, sequentially.

chain
```
public static Each chain(java.lang.Iterable<? extends Each> each)
```
