Field Detail

### m_countMatchPattern

    public XPath m_countMatchPattern

  **For advanced use only** Only nodes are counted that match this pattern.

### m_fromMatchPattern

    public XPath m_fromMatchPattern

  **For advanced use only** Specifies where to count from. For level="single" or level="multiple": Only ancestors that are searched are those that are descendants of the nearest ancestor that matches the from pattern. For level="any: Only nodes after the first node before the current node that match the from pattern are considered.

### m_level

    public int m_level

  **For advanced use only** When level="single", it goes up to the first node in the ancestor-or-self axis that matches the count pattern, and constructs a list of length one containing one plus the number of preceding siblings of that ancestor that match the count pattern. If there is no such ancestor, it constructs an empty list. If the from attribute is specified, then the only ancestors that are searched are those that are descendants of the nearest ancestor that matches the from pattern. Preceding siblings has the same meaning here as with the preceding-sibling axis. When level="multiple", it constructs a list of all ancestors of the current node in document order followed by the element itself; it then selects from the list those nodes that match the count pattern; it then maps each node in the list to one plus the number of preceding siblings of that node that match the count pattern. If the from attribute is specified, then the only ancestors that are searched are those that are descendants of the nearest ancestor that matches the from pattern. Preceding siblings has the same meaning here as with the preceding-sibling axis. When level="any", it constructs a list of length one containing the number of nodes that match the count pattern and belong to the set containing the current node and all nodes at any level of the document that are before the current node in document order, excluding any namespace and attribute nodes (in other words the union of the members of the preceding and ancestor-or-self axes). If the from attribute is specified, then only nodes after the first node before the current node that match the from pattern are considered.

### m_valueExpr

    public XPath m_valueExpr

  **For advanced use only** The value attribute contains an expression. The expression is evaluated and the resulting object is converted to a number as if by a call to the number function.

### m_format_avt

    public AVT m_format_avt

### m_lang_avt

    public AVT m_lang_avt

### m_lettervalue_avt

    public AVT m_lettervalue_avt

### m_groupingSeparator_avt

    public AVT m_groupingSeparator_avt

### m_groupingSize_avt

    public AVT m_groupingSize_avt
